浅谈衰老矿井复采工作面探放水技术

Practice of water detection and water release in repeated mining face in aging mines

复采工作面掘进施工时,通过对附近上分层采空区老空水进行分析和积水量预测,按照有掘必探原则实施了打钻探放水,共放出采空区老空水15 426 m3,消除水害隐患,保证了复采工作面安全掘进。

During the roadway tunneling of repeated mining face,by the analysis and prediction of water accumulation in up goaf,water detection and water release was implemented,about 15426m3 goaf water was discharged,water hazard was eliminated and safety tunneling of repeated mining face was ensured.
