摘　　要：水害是威胁煤矿安全生产的重要因素之一,随着煤矿开采深度逐步延深,水文地质条件变得愈加复杂,煤矿对水害的防治难度也随之加大。详细研究矿井开采受水害影响程度,对矿井防治水工作难易程度进行评价,实施有效的防治水措施是煤矿减少水害发生的重要手段。本文在充分研究矿井水文地质条件的基础上分析了矿井水害因素。研究认为:矿井受水害影响程度大的有老空水和地表水,防治水工作难度高,工程量大;对矿层充水影响程度较大的有断层构造水、钻孔水、岩溶水及矿层直接顶、底板水,防治水工作难度较高,工程量较大;其他水害对矿层充水影响程度较小,防治水工作难度较低,工程量较小。从而提出相应的防治水措施建议,促进煤矿的安全开采。Water hazard is one of the important factors that threaten the safety of coal mine production,and with the gradual extension of coal mining depth,the hydrogeological conditions have become more and more complex,and the difficulty of preventing and controlling water hazard in coal mines has also increased.It is an important means to reduce the occurrence of water hazards in coal mines by studying the degree of water hazards in mine mining in detail,evaluating the difficulty of mine water prevention and control,and implementing effective water prevention and control measures.In this paper,the factors of mine water hazard are analyzed on the basis of a full study of the hydrogeological conditions of the mine.It is concluded that the old empty water and surface water are greatly affected by water disasters in the mine,and the water prevention and control work is difficult and the amount of work is large.The water from the fault structure,the borehole water,the karst water and the direct roof and floor water of the ore layer have a great influence on the water filling of the ore layer,which is difficult to prevent and control water and the amount of work is large.Other water hazards have little impact on the water filling of the ore layer,and the difficulty of water prevention and control is low,and the amount of work is small.Therefore,the corresponding water prevention and control measures are put forward to promote the safe mining of coal mines.
