摘　　要：为了研究主焦煤矿新采区开采后对邻近岳城水库的影响,采用概率积分法和数值模拟确定新采区开采后对地表的主要影响范围,通过数值模拟研究开采后作用在大坝不同位置作用力。结果表明:通过确定地表的基本移动参数,采用概率积分法预测的新采区采空后最大影响范围为336m,数值模拟新采区开采东边界、北边界向外,地表发生下沉和移动区域的宽度分别约为260m、350m,与概率积分法预测结果接近。此外主焦煤矿新采区主要影响范围边缘,距离岳城水库大坝尚有5.1km,且岳城水库大坝未因主焦煤矿开采产生明显位移和应力变化,因此主焦煤矿新采区开采对岳城水库大坝基本无影响。In order to study the influence of the new mining district of Zhujiao Coal Mine on adjacent Yuecheng Reservoir,the probability integral method and numerical simulation are used to determine the post-mining influence range on surface above the new mining district,and the post-mining stress distribution on the reservoir’s dam is simulated,the results show that:by determining the basic movement parameters of the surface,the maximum influence range of the new mining district after being mined out is 336 m according to probability integral method;and according to the numerical simulation,outward the east and north boundaries of the new mining district,the width of surface subsidence area and movement area is about 260 m and 350 m respectively,which is close to the result of probability integral method.In addition,the edge of main influence area of the new mining district is 5.1 km away from the Yuecheng Reservoir Dam,which has no obvious displacement and stress changes due to the mining,the mining influence can be ignored.
