摘　　要：环境影响评价报告中,用概率积分法预计地表移动和变形最大值,相关的预计参数有:下沉系数q、主要影响角正切tgβ和水平移动系数b。在预计参数在无实测值时,可采用岩性综合评价系数P。论文在无地表沉陷实测数据时利用P系数(岩性综合评价指数)给出了预计参数的确定方法,并对陕西神木县某新建矿井一工作面进行了地表最大变形预计。In the environment influence evaluation report,probability integration was applied to predict the max value of the surface ground movement and deformation.The related predicted parameters would include the subsidence coefficient q,the tangent of the main influence angle tgβ and the horizontal movement factor b.When the predicted parameters have no site measured values available,the comprehensive evaluation coefficient P of the lithology could be applied.When there was no surface ground subsidence data site measured available,the P parameter（the comprehensive evaluation coefficient P of the lithology） could proved the method to set the predicted parameters.A max surface ground deformation for a coal mining face of a new coal mine in Shenmu Country of Shaanxi Province was predicted.
