摘要
针对恒源矿井山西组6煤层底板灰岩承压含水层赋存条件,采取地质补勘,采区、工作面优化设计,工作面探查、测试,局部底板注浆加固,疏水降压,利用地面注浆站注浆改造底板含水层等措施,形成了"勘查"、"预测"、"井下物(钻)探"、"评价"、"措施"、"检查""监测"和"防护"八位一体防治水模式,有效地排除了底板水患,避免了底板水害事故的发生。
For occurrence of confined water in floor limestone of 6 Coal Seam in Heng-yuan Mine, this paper put forward applying addi- tional geological exploration, optimization design for mining section and mining face, face exploration and test, local reinforcement with grunting into floor, pressure-relief by dewatering, changing floor aquifer by grunting from surface station to forming a set of water pre- vention methods including exploration, prediction, underground geophysical prospecting, evaluation, measure, inspection, monitoring and prevention. The application of these methods has eliminated effectively floor flood.
