神木矿区的主要环境地质问题

神木矿区地处陕北侏罗纪煤田的北部,毛乌素沙漠边缘。矿区地质环境脆弱,地下水资源贫乏,煤层自燃严重,火烧岩广泛分布。本文对矿区建设及开发中的环境工程地质、环境水文地质问题进行了分析。主要包括火烧岩的工程地质问题,煤自燃,煤矿顶板冒落地面变形,地下水资源枯竭与水污染等问题。

ENVIRONMENTAL GEOLOGY IN SHENMU MINING AREA

The Shenmu mining area is situated in the northern part of North Shaanxi Jurassic coal fieldand the edge of Mn Us Descrt. The geological environment is very fragile, with shortage of groundwater, critical spontaneous combustion of coal seams and large distribution of burn rock in mining area. The paper analyzes the problem of eavironmental engineering geology and envionmental hydrogeology, including engineering geological problem of burn rock, spontaneous combustion of coal, roof collapse and land surface deformation, drying up and pollution problems of groundwater.
