摘　　要：根据工程实际,应用模糊数学的Fuzzy测度模型,将复杂条件下开采地表移动变形问题视为一模糊事件,对煤矿开采引起的地表移动变形问题进行了分析研究,推导了相关的地表下沉、水平变形、倾斜及曲率的理论计算公式,同时利用BP神经网络方法确定了模型的相关参数。通过工程实例应用分析表明,该方法所得的理论结果与实际情况相符合。According to actual engineering,by using the Fuzzy measure model in fuzzy mathematics,the ground deformation and displacement due to underground mining under complex conditions is considered as a fuzzy event in this paper.The ground movement and deformation due to underground coal mining is analyzed and researched.The theoretical formulas of surface subsidence,horizontal deformation,tilt and curvature are deduced.At the same time,the BP neural network method is used to determine the related parameters of the model.An engineering example analysis shows that theoretical result is consistent with the actual situation.
