The Surface Mining Control and Reclamation Act of 1977 (SMCRA) prohibits surface coal mining within the boundaries of any unit of the National Park System. SMCRA also provides the NPS with authority over permitting decisions regarding external surface coal mining.Numerous surface coal mining operations exist or are proposed near NPS units nationwide.Protection of downstream water resources as well as air wildlife habitat and visual resource impacts are often factors that must be addressed ...

OSMRE Regulating Coal Mines

Most coal-mining States now have the primary responsibility to regulate surface coal mining on lands within their jurisdiction with OSMRE performing an oversight role. OSMRE also partners with States and Indian Tribes to regulate mining on Federal lands and to support States' regulatory programs with grants and technical assistance.

Best Practices For Dust Control In Coal Mining

For coal mining operations quartz levels up to 5% in compliance dust samples do not alter the respirable dust standard of 2 mg/m. 3. However if the percent of quartz in the sample exceeds 5% a reduced dust standard is calculated by dividing 10 by the percent quartz.

The hazard chain of rib spalling roof collapse and support instability occurring in steeply dipping coal seams (SDCSs) significantly threatens the safety and productivity of underground mining. A three-dimensional coal wall model was established considering the damage to the coal wall from the abutment pressure based on the new concept of the main control weak surface (MCWS) defined by the ...

Best practices for dust control in coal mining

The intent was to identify the best practices that are available to control respirable dust levels in underground and surface coal mining operations. This handbook provides general information on the control technologies along with extensive references.

Surface Mining Control and Reclamation Act of 1977 - Wikipedia

The Surface Mining Control and Reclamation Act of 1977 is the primary federal law that regulates the environmental effects of coal mining in the United States. SMCRA created two programs: one for regulating active coal mines and a second for reclaiming abandoned mine lands. SMCRA also created the Office of Surface Mining an agency within the Department of the Interior to promulgate regulations to fund state regulatory and reclamation efforts and to ensure consistency among state regulatory p

OSMRE Regulating Coal Mines

The Surface Mining Control and Reclamation Act (SMCRA) balances the need to protect the environment from the adverse effects of surface coal mining with the Nation's need for coal as an essential energy source. It ensures that coal mining operations are conducted in an environmentally responsible manner and that the land is adequately reclaimed ...
