Framework of German mining law

Federal Mining Act (Bundesberggesetz, BBergG) runs since 1st January 1982 is based on the principle of distinction between what is an integral part of the is based on the principle of distinction between what is an integral part of the

ground (grundeigen) and what is not (bergfrei) most raw materials listed in the Act (e.g. metals, salts, hard coal and lignite,

t l t l fl d b it ) t t f l d d tpetroleum, natural gas, fluorspar and barites) are not part of landed property non-integral raw materials are initially ownerless (herrenlos) only a very few mass raw materials (e g sand gravel natural stone peat) only a very few mass raw materials (e.g. sand, gravel, natural stone, peat)

are excepted from this ruling and regarded as the landowner’s property Federal Mining Act regulates the exploration, extraction and treatment of

mineral resources and the rehabilitation of the surface (e.g. recultivation of exploited open cast mines, completed heaps and closed plants)


Objectives of mining law permits

securing the country’s supply of raw materials by orderly exploration, extraction and treatment of the raw materials control of the economy by orderly issue of entitlements

ensuring the safety of the mining operations and their employees i hi d i d h f f h d l i f i i protecting third parties and the surface from hazards resulting from mining

operations also includes compensation for damage caused by mining subsidence p g y g

and reducing the impact on the environment since 1990 environmental impact assessment with public participation to

increase the environmental protection aspects is implementedincrease the environmental protection aspects is implemented

Legal framework of chartered mine surveyors (1)

§ 63 BBergG: the mining entrepreneur is obliged to maintain cartographic documentation of extraction and underground exploration operations

the documentation consists of the mine plan and other documents the documentation consists of the mine plan and other documents(maps, plans, survey reports and files) and is to be updated regularly(Rißwerk = Grubenbild + sonst. Unterlagen)

if someone is affected by subsidence he can inspect the relevant if someone is affected by subsidence, he can inspect the relevant documentation at the mining authority (Grubenbildeinsichtnahme)

§ 64 BBergG: the documentation is to be maintained by an officially recognized mine surveyor (Markscheider)recognized mine surveyor (Markscheider)

the mine surveyor is not subject to directives in the performance of his professional duties (Weisungsfreiheit)

he is authorized to certify facts within the scope of his activities(similarly to notaries public and publicly appointed land surveyors)(Öffentlicher Glaube)


Legal framework of chartered mine surveyors (2)> Measurements vs. Monitoring <

§125 BBergG: the mining authority may require observations (measurements) in areas with buildings and facilities on the surface to identify and monitor thein areas with buildings and facilities on the surface to identify and monitor the effects of mining (ground movements). if these measurements are relevant in preventing a danger

Monitoring is not defined in mining law. This “technical term” covers all relevant environmental observations ensuring the aims of the approval.relevant environmental observations ensuring the aims of the approval.

Monitoring in this case, as an administrative and functional instrument, is an integral part of long term permits and of common use.

Radar interferometry – status quo and capabilities (1)

operational terrestrial and airborne sensors are available the availability of suitable international satellites appears assured the availability of suitable international satellites appears assured

a high repeat rate is ensured with satellites i b d il bl f diff t f ti various wavebands are available for different functions data archives are available and in construction

satellite scenes covers large areas in good quality the suitability for detection of relative height changes is good (!)

geometric accuracy has been confirmed by geodetic methods geometric accuracy has been confirmed by geodetic methods PSI/IPTA supplies good point-related results dInSAR supplies good area-related results


Radar interferometry – status quo and capabilities (2)

the market is coming alive alternatives are available among data providers service providers and alternatives are available among data providers, service providers and

clients also (!) acceptance of the results is increasing a critical attitude towards the black box system is still appropriate data and process costs are regrettably still much too high (!)

the technology is approaching general market readiness another 3-5 years will pass until it is accepted as a replacement for terrestrial another 3 5 years will pass until it is accepted as a replacement for terrestrial

methods (levelling) will be further on an technology managed by experts only (!)


Radar interferometry – what remains to be done? (1)

the fields of use under mining law, the requirements for the measurements and documentations and the accuracies to be maintained has to be clarifiedand documentations, and the accuracies to be maintained has to be clarified

the legal certainty of the results has to be clarifiedg y

euphoric application and marketing scenarios should be abandoned

Conclusion 1: confidence has to be build


Radar interferometry – what remains to be done? (2)

the availability of the sensors and service chain has to be ensured market mechanisms have to be improved and costs cut market mechanisms have to be improved and costs cut handling and decision-making aids for selection of the right method

have to be created further regional, national and international projects and field tests are

necessary to strengthen and to propagate the know-how reporting in popular science media has to be increased reporting in popular science media has to be increased

Conclusion 2: market has to be developed
