摘要
根据钱家营矿的水文地质资料,分别采用"安全水头值"法和"突水系数"法预测评价研究区的奥灰水带压开采问题,分别论证得出钱家营井田内不存在带压开采危险性和研究区的突水系数规律,证实全区奥灰水突水系数均小于0.06 MPa/m,不存在带压开采的突水危险性。
Based on Hydrogeological data of Qianjiaying Mine,safety value and water inrush coefficient method were adopted separately to appraise grey water with pressure mining problem,the result showed that Qianjiaying coalfield was without mining with pressure danger,and got water inrush coefficient rule,the area grey water water inrush coefficient was less than 0.06 MPa/m,without mining with pressure danger.
