准格尔矿区环境水文地质问题及对策

THE ENVIRONMENTAL HYDROGEOLOGICAL PROBLEM AND ITS CONTROLIN JUNGGHAR COAL MINING AREA

准格尔矿区地下水开采资源量为１６７６０ｔ／ｄ，而开采量为７４９７３ｔ／ｄ，长期开采将引起一系列环境水文地质问题，如泥沙充填带运移和水质恶化，所以应合理开采地下水资源；开拓新的供水水源；建立新的供水水源地；减少集中开采；建立地面污水处理系统。

In Jungghar coal mining area the exploitable resource of groundwater is 16 760 t/d and the mining yield is 74 973 t/d.The longterm pumping will cause a series of environmental hydrogeological problems such as the migration of filled belt by mud and sand,as well as the deterioration of groundwater quality.Therefore,it is very important to rationally pump the resource of groundwater,develop new water supply sources,build up new water source regions,reduce the concentrative mining,establish regional sewage treatment system and avoid draining the sewage into subsurface.
