摘　　要：矿井水害是制约煤矿安全生产的不利因素之一,掌握矿井水文地质特征及水害对煤层开采的影响程度有助于针对性地制定防治水方案。灵北煤矿开采2_(下)号、5号、9号、10(10+11)号、11号煤层,采掘工程受大气降水和地表水影响小,煤层顶板含水层对煤层开采威胁程度相对较小,而在地质构造发育区底板奥灰水有突水可能。灵北煤矿防治水工作重点为采空区积水探放及隐伏断裂构造的探查,防治水工作易于进行,防治水工作难易程度为中等。Mine flood is one of the unfavorable factors that restrict coal mine safety production.Understanding the hydrogeology characteristics of mines and the impact of flood on coal seam mining can help formulate targeted water prevention plans.Based on the analysis of the hydrogeology characteristics and water disaster influence in Lingbei Colliery while mining coal seams 2_(下),5,9,10(10+11),and 11,the paper concludes that the focus of water prevention in Lingbei Colliery is to explore and release accumulated water in goaf and explore hidden fault structures,water prevention is easy to carry out,but the difficulty level of water prevention and control work is moderate.
