Assessing the impact of opencast coal mining on water quality Executive Summary The European Directive on Groundwater (80/68/EEC) was fully transposed into Scottish law by the introduction of the Groundwater Regulations 1998. These regulations forbid the introduction of certain substances (denoted as "List I substances") into groundwater, and also place limitations on the extent to which other ...

China, as the largest coal-producing and -consuming country in the world, is highly dependent on its coal industry, or “Black Gold” industry, for the national energy and economy. The consequent environmental crises, however, have persisted for decades, and the most serious effect is surface subsidence induced by underground mining. Underground coal excavation in China has ignored this problem f...

Automation in underground mining enhances safety and leads to economic efficiencies. After more than 50 years of research, automation tasks have gradually been growing out of the classic engineering/mechanical environment and require a sophisticated datamining treatment. The success of (mechanical) process automation has left only one remaining place in the coal-excavation process where human l...

coalbed methane (cbm) plays an important role in coal mining safety and natural gas production. in this work, the cbm potential of b2 seam in parvadeh iv coal deposit, in central iran, was evaluated using a combination of local regression and geostatistical methods. as there were 30 sparse methane sampling points in the parvadeh iv coal deposit, no valid variogram was achieved for the methane c...

The increasing trend of opencast coal mining in India tends to release huge amounts of dust. But there is no well-defined method of estimating dust emission due to different coal mining activities. This paper examines the sources of dust emission due to coal mining activities, and focuses on the quantification of dust emission with the development and use of emission factors. Because of their s...

The Federal Mine Safety and Health Act of 1977 consolidated all federal health and safety regulations of the mining industry-coal as well as noncoal mining-under a single mandate administered by the Mine Safety and Health Administration (MSHA). Today, the agency is striving to reduce the environmental health risks associated with mining.
