摘要
在分析霍宝干河煤矿矿井水文地质条件的基础上,根据《煤矿防治水细则》相关要求对1、2号煤层奥灰含水层带压开采突水系数进行计算,并按突水威胁程度进行了分区,预测了奥灰水突水量,对巷道掘进的安全性进行评价,为煤矿开拓合理规划、采掘工程科学布局以及有针对性地确定带压开采防治对策提供了有力的水文地质依据。
By analysis of hydrogeological conditions in Huobao Ganhe Mine Co.,Ltd.,the author makes a calculation of the water outburst coefficient in mining No.1 and No.2 coal seam with Ordovician limestone water under pressure on the basis of relative requirements in“Detailed Rules and Regulations for Mine Water Control”and makes a safety evaluation of roadway excavation after the zoning according to water outburst threat degrees and water outburst quantity prediction,which can provide a hydrogeological basis for reasonable planning of mine development,scientific layout of mining engineering and corresponding countermeasures in mining under pressure.
