水源地下采煤对水资源的影响及防治措施

分析典型矿井水文地质条件的基础上,通过计算导水断裂带发育高度及采煤沉陷积水区随着煤炭开采的变化情况,研究了煤炭开采对哈头才当水源地水资源的影响,并提出了保护性开采、调整煤炭开采计划和地面设施、采取沉陷积水控制措施等切实可靠的保水采煤的措施。煤炭开采地表移动变形大,形成的沉陷积水区面积较大,水资源损失量大,只有采取切实可行的措施,才能保水采煤。 On the basis of the analysis of the hydrogeological conditions of the typical mine,the height of development of the fracture zone of water guide and the change of the coal mining subsidence area with the coal mining were calculated.The effect of coal mining on the water resources was studie,and measures of protecting water,adjusting the coal mining plan and the ground facilities and control measures of subsidence and water accumulatiowere were put forward.The results show that area of subsidence water accumulation and loss of water resources become larger along with increase of surface movement and deformation of coal mining.Only by taking practical measures can both water and coal be protected
