摘　　要：将山区地下开挖所引起的上覆岩土体的移动视为一模糊事件,应用模糊数学中的模糊测度理论,推导了相应的地表下沉及水平移动的理论计算公式,对煤矿开采所引起的地表移动进行了计算分析。通过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的很好。The rock mass displacement due to underground mining in mountainous areas is considered as a fuzzy event in this paper. The formulas of ground surface subsidence and horizontal displacement are deduced. By using the fuzzy measures theory, the ground surface movement due to underground mining of coal ore in mountainous areas are calculated and analyzed. An engineering example shows that the calculating results tally well with the measuring data.
