矿井突水是影响煤矿安全生产的因素之一,对其进行分析有助于灾害的防治。系统论述了李子埂煤矿地下水赋存特征,根据对其补给、径流、排泄条件,以及赋水特征、水文地质特征等因素的分析,指出造成突水事故原因主要是:矿井突水来源为煤层下伏茅口组P1 m岩溶含水层中赋含的岩溶水,其突水途径为小断裂,突水的水动力条件为矿区煤层下伏茅口组P1 m岩溶水具有承压高水头。同时,矿井突水和龙洞坝泉涌水为同一补给、径流、排泄系统,具有密切的水力联系,龙洞坝泉的短暂断流是煤矿井巷突水造成的。
礦井突水是影響煤礦安全生產的因素之一,對其進行分析有助于災害的防治。繫統論述瞭李子埂煤礦地下水賦存特徵,根據對其補給、徑流、排洩條件,以及賦水特徵、水文地質特徵等因素的分析,指齣造成突水事故原因主要是:礦井突水來源為煤層下伏茅口組P1 m巖溶含水層中賦含的巖溶水,其突水途徑為小斷裂,突水的水動力條件為礦區煤層下伏茅口組P1 m巖溶水具有承壓高水頭。同時,礦井突水和龍洞壩泉湧水為同一補給、徑流、排洩繫統,具有密切的水力聯繫,龍洞壩泉的短暫斷流是煤礦井巷突水造成的。

Mine water inrush is one of the important factors influencing the safe production in coal mines, so the analysis on it contributes to the disaster prevention and control. This paper systematically described the groundwater occurrence characteristics in Lizigeng Mine. Based on the analysis of the groundwater supply, the runoff flow, the discharge condition, the characteristics of groundwater occurrence, the hydro-geological characters and so on, the paper pointed out that the main cause of the water inrush incidents is:the mine water inrush source was the Karst water in Karst aquifer of the underlying Maokou limestone group P1 m of the coal seam, the water inrush pathway was small fractures, and the dynamic conditions of water inrush was the high pressure head of Karst water in Karst aquifer of the underlying Maokou limestone group P1 m of the coal seam. In addition, the coal mine water inrush and Longdongba spring inrush were the same groundwater supply, runoff flow and discharging system, and had close hydraulic relation between them, the transient disappear of Longdongba spring was caused by the mine water inrush.
