我国露天煤矿开采环境问题及防治对策研究论文 Our country opencast coal mine mining environment question and preventing and controlling countermeasure research The world each mining coal country all will give priority to development the open-air mining coal achievement to increase the coaling output the main way, so long as will have the condition, will realize centralism mining as far as possible, by will enhance the labor productivity, will reduce the cost. Our country also is this, regardless of is the early years of the new nation extension and west construction Fushun the strip mine and the Zhugai strip mine, 20th century 60s strip mine and so on constructions Pingzhuang, righteousness horse, Hami, 80s large-scale constructions Imin, Holingol River, Dzungar, the Antai fort and so on several big strip mines, all for our country coal output growth, the national economy national economy construction have made the tremendous contribution, also has obtained the huge economic efficiency. But based on the historical reason, knew the natural limitation and the legal system laws and regulations are imperfect, open-air mining coal industry swift and violent development at the same time, also has brought a series of mines environment question and the ecology destroys, has seriously affected local the ecological environment quality and the economy continues to develop. This is we urgently awaits to be solved the major problem which but also must earnestly treat. 1:opencast coal mine mining initiation environment question Open-air mining coal forms pit, because the geologic structure, side slope reason and so on crag body, surface water ground water function induces the landslide, to cave in, soil erosion, the mud-rock flow and so on a series of geological disaster, also causes the ground to distort but endangers the security which the peripheral locality the industrial enterprise and the inhabitant constructs. Both created the huge economic loss and to destroy the origin
