摘　　要：针对柳山沟磷矿床地下开采自然坡失稳问题,应用模糊测度理论,推导了相应的地表下沉、倾斜、地表曲率、水平移动、水平变形的理论计算公式,对处于山区的柳山沟磷矿床地下开采所引起的地表移动与变形及山体失稳问题进行了具体分析。工程实例计算分析表明,理论计算结果与工程实测资料吻合。In this paper, the application of the fuzzy probability measures to the analysis of the instability of natural slope due to underground mining under the mountain areas in Liushangou phosphorus mine is described. By using the fuzzy measures theory in fuzzy mathematics, the formulas of ground surface subsidence, horizontal displacement, inclination, horizontal strain and curvature are deduced. And the ground surface movement and deformation and the instability of natural slope due to underground mining of the phosphorus ore in Liushan-gou mine in mountain area is calculated and analyzed. An engineering example shows that the calculating results tally well with the measuring results.
