煤矿井下起伏巷道排水系统合理性探讨

Discussion on rationality of drainage system of undulating roadway in mines

为了满足煤矿井下起伏巷道排水需要,保障井下工作人员人身安全及煤矿开采顺利进行,根据湾图沟煤矿井下大巷巷道条件及涌水情况,提出3种可行的排水系统方案。通过技术分析、经济分析及可靠性分析等方式剖析各方案优缺点,最终确定了技术可靠、经济合理的排水系统。结果表明,井下起伏巷道排水系统设计应根据巷道涌水情况、集中排水点设置及巷道情况等客观因素确定,为煤矿井下起伏巷道排水系统的设计提供借鉴。

In order to meet the drainage needs of the undulating roadway in the coal mine,ensure the personal safety of the underground staff and the smooth mining,according to the conditions of roadway and water gushing in Wantugou Mine,three feasible drainage system schemes were given,and the advantages and disadvantages of each scheme were analyzed through technical analysis,economic analysis and reliability analysis,finally,a reliable and economical drainage system was set for the underground roadway of the mine.The research results showed that the design of drainage system of underground undulating roadway should be determined according to the water inflow situation of roadway,the setting of centralized drainage points and roadway conditions,which can provide reference for the design of drainage system of undulating roadway in mines.
