针对淖尔壕煤矿回风大巷巷帮多处发生带压异常涌水情况,为了分析邻近矿井4.1MPa采空区积水、以及淖尔壕矿厚松散层含水层对矿井异常涌水影响,判定异常涌水水源,通过对矿井回风大巷南侧边界煤柱尺寸探测、煤层物理力学性质测试、边界煤柱稳定性验算、顶板富水性探测等手段开展现场实测和理论研究,结果表明回风大巷南侧井田边界煤柱尺寸约35m,满足安全煤柱留设要求,回风大巷异常涌水水源判定为顶板含水层富水区砂岩水,为矿井进一步采取水害防治措施提供指导.%Abnormal water burst appeared at some position of ventilation roadway side of Zhuoerhao coal mine,in order to analysis the influence nearby 4.1MPa goaf water and thick alluvium aquifer of Zhuoerhao coal mine to abnormal water burst,then abnormal water burst source was determined,according field test and theoretical study,coal pillar sizes exploration of south side of ventilation roadway,coal seam physical and mechanical property testing,stability calculation of coal pillar,exploration of roof waterly,the results showed that mine field boundary coal pillar sizes of ventilation roadway south was 35m,it satisfied safety of coal pillar set,abnormal water source was sandstone water of roof aquifer,and these reference for water damage control.
