With the rapidly development of minefield and the rapidly increase of coal output, the excavation scope and depth will extremely rise, the excavation work is under the overlying by the thin rock strata, and under the thick loose bed, the population in mine field will be more and more, the relevant basic industries will also develop rapidly. the mines will discharge more water from the underground, and the production and living will also consume more water. so the original water resource balance system in the minefield will be broken, the ecological environment formed by the nature will be destroyed in some degree
隨著礦區迅速發展而煤炭產量的快速增長，既定在薄基巖厚鬆散層下的神東煤田開采范圍和深度勢必急劇增大，相應的人口也增加，與其相匹配的其它基礎工業一併迅猛發展，導致礦井外排水和生產生活用水直線猛增，這一系列生產和生活巨量用水必然會打破礦區原始的水資源平衡體系，不同程度的破壞自然形成的脆弱的生態環境。 -
