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 Hengyuan Mine, this paper put forward applying additional 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 prevention methods including exploration, prediction, underground geophysical prospecting, evaluation, measure, inspection, monitoring and prevention. The application of these methods has eliminated effectively floor flood.
