摘要
老空区积水严重影响工作面的安全高效开采,针对由于历史原因形成的分布范围不确定的采空区,三道沟煤矿通过对水文地质和采空区积水探查,并结合现场实际条件,采用ZLJ2900、ZDY1200S和ZDY6000LD(A)型煤矿用履带式全液压坑道钻机施工,对采空区积水采用合理的探放水设计,确保工作面正常回采。
Old empty area water seriously affect the safe and efficient mining of working face,for historical reasons with the distribution range of uncertain mined-out area,the Sandaogou Coal Mine based on hydrogeology and goaf water detection,and connecting with the actual conditions,adopt ZLJ2900,ZDY1200S and ZDY6000LD type(A)coal mine with crawler hydraulic tunnel drilling rig construction,the goaf water use reasonable drain design,to ensure the normal mining working face.
