摘　　要：针对目前任意形状工作面预测方法存在的不足之处,在概率积分法理论基础上,应用地理信息系统(GIS)技术,提出了基于GIS的任意形状工作面预测概率积分算法。将任意形状工作面剖分成若干个非结构化三角形,利用复化辛普森二重积分法对每个三角形区域按正态积分函数进行预测计算,最后将各个三角形区域积分计算值进行叠加,实现对任意形状工作面的预测。依据此算法开发了开采沉陷预计系统,以某煤矿为实例进行了验证,预计结果和现场实测结果基本吻合,系统具有计算方便、使用简单、能高效进行前后数据处理等特点,适用于缓倾斜、倾斜煤层任意形状工作面的地表移动和变形计算,可为"三下"采煤提供地表移动预测计算的支持。In accordance with the shortage in mining subsidence prediction methods of arbitrary shape face at present, this pa- per presented a GIS-based probability integral algorithm to predict mining subsidence for arbitrary shape face by applying the theory of probability integral method and geographic information system （GIS） technology. It divided the arbitrary shape face into several unstructured triangles, and adopted the double integral composite Simpson method to conduct the integration in every triangle region according to the Gaussian integral function to predict calculation, and calculated every triangle region integral value to realize the prediction of arbitrary shape face through superposition method. Based on the algorithm, it developed a system used for mining subsidence prediction of the arbitrary shape face, conducted a case study of predicting the mining subsidence to test the developed system. The results show that the system can be used to calculate surface movement and deformation for the arbitrary shape face in the gently inclined and inclined coal seam, which can provide an easy way to process the prepost data with the functionalities of convenience, simplicity, and efficiency. Also, the system can provide the support for ＂under three＂ coal mining with surface movement prediction.
