摘　　要：针对郑煤集团杨河煤业31采区东翼上部魔洞王水库及水库堤坝的采动损害问题,通过概率积分法函数对31071工作面上方地表移动观测站实测数据进行曲线拟合,得到地表移动和变形的概率积分法参数和角量参数。利用地表移动变形曲线分析了受采动影响下地表移动和变形规律。结果表明,通过对水库和堤坝区域内进行限采措施以后,试采工作面对水库和堤坝产生一定的损害,达到Ⅰ级,采区内各工作面开采后对堤坝损害程度最大达到Ⅱ级,未超过"三下规程"允许变形值。Focusing on the problem of a Modongwang reservoir and its dam structure above the 31 district of Yanghe coal east wing on Zhengzhou coal group,the probability integral method parameters and angular parameters of surface movement and deformation were obtained by means of the probability integral method for the curve fitting of the measured data of the 31071 working face above the surface observation station.The law of surface movement and deformation affected by the influence of mining was analyzed by using the surface movement deformation curve.The result show that,by the restrictive production measures in the area of reservoir and dam,it appeared a certain level of damage and reached the levelⅠin the end of the testing working face,then after the exploitation of all the mining face in the region,the dam will achieve the maximum extent of the damage with the levelⅡ,which does not exceed allowable deformation value of coal mining rules under baildings,railways and water bodies.
