A building project in a mining area requires an additional review under the Mineral Resources Act. Section 153(2) MinroG generally requires a separate permit for buildings and other facilities that are not mining facilities. This permit is required in addition to the building-law permit.

The decisive points are the exact status of the area, the planned facility and its possible effects on extraction or storage operations. The review also covers material extensions and alterations to an existing facility.

This article explains which documents owners and project teams should collect at an early stage. It also explains when ground deformation or planned extraction may prevent a permit. Voluntary use of land against compensation and compulsory transfer of land remain outside this article.

Initial orientation

Does your project require a mineral-law review?

Two short questions indicate which documents should be checked first.

Already know you want to get in touch? Go straight to the enquiry form.

01 Question 1

Has the status of the property been clarified?

The status may appear in official decisions, the land register or documents held by the mining-rights holder.

All paths at a glance

Overview of all answers.

01

Without a clear area status the permit requirement cannot be assessed reliably.

Obtain the relevant decision, the land-register extract and the project documents held by the mining-rights holder. Assign the affected area precisely in an up-to-date site plan.

Only then can you assess whether section 153(2) MinroG requires a separate application and which effects the planned extraction may have.

02

A new building or material alteration should be prepared for an application under section 153(2) MinroG before construction starts.

Have an authorised person prepare the description and plans of the project. At the same time review the building-law application and the possible effects on extraction, storage and ground deformation.

The permit position should be documented before a binding commission and before work begins.

03

The type of facility determines which review is required under the Mineral Resources Act.

Classify the planned work from a technical perspective. Section 153(2) MinroG concerns buildings and other facilities that are not mining facilities. Apparent maintenance may require a different assessment if it includes material alterations.

Keep the existing structure, the planned alteration and the purpose of the facility clearly separate in the documents.

Which areas qualify as mining areas under MinroG?

Section 153(1) MinroG connects the term mining area to defined mining-law areas. These include plots and plot sections within the boundaries of mine measurements and overlying claims. Storage fields and extraction fields are also included where the statutory exception for hydrocarbon deposits applies. Areas covered by an approved extraction operating plan for minerals owned by the landowner may also qualify.

A mining area may also be designated by an official decision under section 154(2) MinroG outside those areas. This concerns plots where planned and systematic extraction or storage operations are expected to cause ground deformation within the next fifteen years. The deformation must be capable of materially changing buildings or other facilities. The authority designates the affected plots and plot sections by decision.

For owners the first practical step is therefore to identify the exact area. The land register may provide an important indication. Section 155 MinroG provides that the authority informs the land-register court about plots or plot sections that qualify as mining areas. The land-register court then records this status ex officio. The entry does not replace a review of the specific project.

When does a building project need an additional permit?

Under section 153(2) MinroG buildings and other facilities that are not mining facilities may only be built in a mining area with an authority permit. The rule also covers material extensions and alterations. A house, a larger commercial facility or a material alteration to an existing structure may therefore require a mineral-law permit in addition to the relevant building-law procedure.

The two procedures answer different questions. Building law assesses the project under the applicable regional building rules. The permit under section 153(2) MinroG also protects extraction or storage operations and considers possible mining-related ground deformation. A building permit therefore does not automatically resolve the mineral-law question.

The exception for mining facilities must be assessed for the actual project. The function of the facility and its connection with the mining operation are decisive. A label in the building application is not enough. The classification should be clear from the plans, the project description and the documents concerning the mining right.

Which documents must the permit application contain?

Section 153(2) MinroG requires two copies of a description and plans of the project prepared by an authorised person. The documents must therefore do more than provide a general sketch. They should show which facility is to be built or altered on which plot section.

For the practical review this normally means an up-to-date site plan, understandable floor plans and sections as well as a description of the intended use. For an extension the plans should clearly show which parts are existing and which parts are new. The documents must also connect the project to the mining area and the expected operation.

Technical safeguards deserve their own explanation where ground deformation is possible. Depending on the project they may include the structural concept, foundation design, movement joints or monitoring. The statute does not provide one general checklist for every project. The documents must explain the specific risks so that the authority can assess section 156 MinroG.

When can the mineral-law permit be refused?

Section 156(1) MinroG sets out three separate grounds for refusal. A permit must be refused if the planned building prevents or substantially impedes extraction or storage operations in the mining area. There is an important statutory exception: the mining-rights holder may accept the substantial impediment.

The second ground concerns ground deformation. A permit may be refused if a material change to the building or other facility cannot be ruled out because of ground deformation and suitable measures or safety precautions cannot prevent that risk. The authority must therefore assess the technical forecast together with the proposed safeguards.

The third ground applies if the planned building makes it impossible to extract the deposit as completely as possible. The review therefore concerns the specific deposit and the specific plan. A general statement that building is forbidden in every mining area would go too far. The project documents and mining records must establish the relevant facts.

Review fields

Bring building law and mineral law together

The procedures answer different questions. Both levels must be consistent before construction starts.

Review matrix for a building project in a mining area
Review field What is examined? Important evidence
Area Does the plot qualify as a mining area under section 153 or section 154 MinroG? Relate the decision, land-register status and site plan to the same area.
Facility Is this a building, a material alteration or a mining facility? Describe the existing structure, purpose and extent of the project clearly.
Mining Will extraction or storage be prevented, impeded or made incomplete? Review the mining right, the operation and the planned extraction.
Ground Could ground deformation materially change the facility? Provide a technical forecast and suitable safety measures.

The matrix does not replace a review of the specific plots, plans and mining records.

How are ground deformation and the extraction period assessed?

Section 154(1) MinroG concerns plots outside certain mining-law areas where planned and systematic extraction or storage operations are expected to cause ground deformation within the next fifteen years. The deformation must be capable of materially changing buildings or other facilities. The forecast therefore concerns the effects of the operation rather than a general assumption about the ground.

The mining-rights holder must notify the authority of the plots or plot sections that may be affected. The documents include a list, a site plan, a mining survey map and a technical mining description. The authority then assesses whether the statutory conditions are met and which areas it designates as mining areas by decision.

Section 156(4) MinroG sets an important limit for the refusal assessment. A permit must not be refused if mining use of the plots is not expected within fifteen years. The mining-rights holder must make this credible. An up-to-date and comprehensible timetable for the mining operation is therefore important for the project side.

How can the building procedure be coordinated with mining law?

A sound sequence begins with the area review. Owners should clarify whether the area is defined by a mine measurement, an overlying claim, an extraction field, a storage field, an extraction operating plan or a decision under section 154 MinroG. The classification of the facility can then be discussed with the relevant authorities and professionals.

Building plans and mineral-law project documents should then be aligned. A site plan with inconsistent area descriptions makes a decision more difficult. The same applies to a building description that explains the use but says nothing about effects on extraction or storage operations.

Section 153(2) MinroG generally provides a decision period of three months from submission of the application. The authority may extend this period by up to three months by decision if the matter cannot be clarified within the first three months in the circumstances of the case. Project schedules should allow for this possibility. Work should begin only once the permits required for the specific project and their conditions are clear.

Process

Four steps to a reliable permit position

A clear sequence connects the area status, project plan and technical evidence.

  1. 01
    Step 1

    Identify the area

    Relate decisions, the land-register extract and mining documents to the affected plot sections.

  2. 02
    Step 2

    Classify the facility

    Distinguish a new building, material alteration, extension and mining facility by purpose and plans.

  3. 03
    Step 3

    Prove the risks

    Explain effects on extraction, storage and ground deformation with technical documents.

  4. 04
    Step 4

    Coordinate the application

    Align the description and plans under section 153(2) MinroG with the building procedure and schedule.

Practical tip: Before buying the property or commissioning the works place the land-register extract, all indications of a mining area, the building plans and the mining documents side by side. This often reveals early if the area, use or timetable do not match. For an initial legal assessment you can book an initial consultation.

What should owners clarify before a purchase or building contract?

When buying a property any indication of a mining area belongs in the legal and technical review. The land-register extract is a starting point. Decisions, site plans, project documents and information from the mining-rights holder should also be checked. The review must concern the actual plot and the planned building.

Before commissioning construction it should be clear who prepares the description and plans required by section 153(2) MinroG. It is equally important to identify who provides technical evidence on ground deformation and who answers questions from the authority. The contract should describe these responsibilities clearly.

If the permit position is open the contract should reflect the outstanding conditions. These may concern particular documents, clarification of the mining use or a coordinated application. A general promise that the property is buildable does not replace the review under sections 153 and 156 MinroG.

Which mistakes put a mining-area project at risk?

A common mistake is to consider only the building permit. If the mining-area issue is addressed after the application has been filed, plans and the schedule may need to be changed later. The additional permit should therefore be reviewed during project development.

Unclear area descriptions create another problem. A decision may concern plot sections. If the building plan, land-register documents and technical mining description use different designations there is no reliable basis for a decision.

Technical statements must also be specific. A general assurance that the building will have a safe foundation does not answer the question of possible ground deformation. The documents must explain the effects and the planned safeguards. Finally the mining timetable should be checked because the expected extraction period may be relevant under section 156(4) MinroG.

FAQ

Building projects in mining areas

Does every building project in a mining area need an additional permit? +

Section 153(2) MinroG generally requires a permit for buildings and other facilities that are not mining facilities. The rule also covers material extensions and alterations. Whether a specific measure is covered depends on its type, extent and the status of the area. Regional building permits or other procedures may also be required.

How long may the authority take to decide the application? +

Under section 153(2) MinroG the permit is deemed granted if it is not refused within three months after the application has been submitted. The authority may extend the decision period by up to three months under the statutory conditions. The actual period requires a review of submission, completeness and the content of any decision.

Can a permit be refused because of possible ground deformation? +

Yes. Section 156(1)(2) MinroG covers this situation. Refusal may be considered if a material change cannot be ruled out and suitable measures or safety precautions cannot prevent the ground deformation or its effects. The technical forecast and the proposed measures must therefore be assessed together.

Which documents should I check before buying a property? +

Check the land-register extract, decisions, site plans, indications of mine measurements, overlying claims or extraction fields as well as the documents concerning the mining operation. Relate every document to the same area and planned building. This shows early whether an application under section 153(2) MinroG should be prepared.
