摘　　要：王河煤矿位于荥巩矿区中部,单一开采太原组一1煤层,属带压开采,为荥巩矿区矿井水害最为严重的矿井之一.该矿自投产以来累计发生突水事故达50余次,并造成淹井2次.本文通过对王河井田地质、水文地质条件、突水点分布规律和突水强度特征的分析研究,阐明了矿井突水事故频发的原因,论述了地质构造条件、一1煤层底板隔水层厚度、含水层富水性、矿山压力、水压与突水的关系.在此基础上,提出了矿井防治水害的方法和措施,为今后该矿的安全生产指明了方向.Wanghe coalmine lies in the middle of Xinggong coalfield, 一1 coal seam of Taiyuan Group only. It belongs to the kind of mining under safe water pressure of aquifer. Wanghe coalmine is one of the most serious of coal mine water calamity in Xinggong coalfield. Accumulatively, more than 50 water inrush accidents have happened, twice coal mine submerged accidents since the coal mine put into production. In this paper, by analyzing the geologic and hydrogeologic condition of Wanghe coalmine, the distribution of water inrush spots, water inrush strength character, and reasons of high frequency of water inrush accidents are elucidated. The relations between the geological structure and water inrush, the thickness of一1 coal seam floor aquifuge and water inrush, the water abundance of aquafer and water inrush, the mine pressure and water inrush, water pressure and water inrush are discussed. Based on the analysis and investigation of above, the methods and countermeasures to prevent water inrush are put forward which will guide the safe production of coalmine.
