摘要
资源整合矿井存在许多老空区积水,探放老空区积水是为保障矿井安全最有效的措施之一。根据亿欣煤业的地质及水文地质资料,在探放老空水时采取主动探放原则,在亿欣煤业采掘工程平面图上认真分析老空区具体位置,确定老空区的积水范围和积水量,对探放水钻孔进行了设计,论证了钻孔涌水量及排水设备选择,提出了相关安全技术措施。探放效果验证在实践工作中应用良好,正确指导疏放了老空区积水,对疏放井田内的老空区积水具有指导意义。
In resource integration mine,exploring and draining water in old goaf is one of the most effective measures to ensure mine safety.According to the mine geological and hydrogeological data,the specific location,water level and water volume of the old goaf were carefully determined,the principle of active exploration and release was proposed in treating goaf water,the drilling holes for water exploration and drainage were designed,the drainage equipment was selected,and the relevant safety technical measures were put forward.Practice shows that the effect of water exploration and drainage measures is good,which has guiding significance for goaf water exploration and drainage in the mine field.
