山西省是我国最大的煤炭能源基地,煤田面积6.18万km ̄2,占全省面积的三分之一以上。探明储量达2048亿吨,年开采量2亿吨以上,本世纪末将达到3亿吨以上。山西的主要煤田(大同煤田例外)均开采石炭、二叠系煤层。含煤地层覆盖于寒武、奥陶系岩溶化地层之上,即煤田与岩溶泉域大部重叠,形成煤、水(岩溶水)共存系统。大规模采煤对岩溶水环境的影响是巨大的,已成为能源基地建设与运营的制约因素。
Shanxi Province is China’s largest coal energy base with an area of 61,800 km2, accounting for more than one third of the province’s total area. Proved reserves of 204.8 billion tons, the annual extraction of 200 million tons more than the end of this century will reach 300 million tons. Shanxi’s major coal fields (Datong Coal Field exception) are the exploitation of carboniferous, Permian coal seam. The coal-bearing strata cover the Cambrian and Ordovician karst formations, ie coalfields and karst springs overlap mostly to form coexisting systems of coal and water (karst water). The impact of large-scale coal mining on the karst water environment is huge and has become a constraint factor in the construction and operation of energy bases.
