摘要
小煤窑采空区积水是威胁矿井安全生产的重大隐患。为了消除阳坪煤矿采空区积水对斜沟煤矿15采区上山大巷掘进的水害威胁,通过地面物探与井下物探、钻探、化探相结合的综合探测方法,结合巷道水文地质条件优化"有掘必探"设计,采用"掘进与探放水并行"的管理模式,确保了15采区皮带上山安全快速掘进到位,并成功探放出11万m3阳坪煤矿采空区积水,彻底消除了采空区积水威胁,优化了矿井采掘部署。
Small coal mine goaf water is a major potential safety hazard in coal mine production. In order to eliminate the threats of goaf water to 15 panel roadway advancing in Yangping coal mine. Adopting comprehensive detection method,which includes ground and underground coal mine geophysical prospecting,drilling and geochemical exploration. In the meantime,optimizes the water exploration design according to the roadway hydrogeological conditions,adopts the management model of tunnelling and surveying water. Ensures 15 panel roadway advancing in place safely and quickly,and 110 000 cubic meter goaf water from Yangping coal mine has been released. Finally,the threats of goal water has been eliminated,and the mining plan of Xiegou coal mine has been optimized.
