【摘要】 在介绍块体稳定可靠性分析各种方法的基础上,分析了采空区块体稳定状态的随机性和模糊性的特点,根据块体理论与模糊分析学中的模糊测度理论,提出了块体稳定性的模糊随机可靠性分析方法,建立了块体稳定性模糊概率测度计算公式,并将该方法应用于浙江遂昌金矿采空区顶板围岩块体稳定性分析的工程实践中,计算结果表明,块体稳定性较差,采空区残留矿柱回采前,需采取相应的安全措施。更多还原

【Abstract】 Based on introduction to various methods of reliability analysis for block stability, fuzzy and random characteristics of block stability in caved area are analyzed. The method of fuzzy random reliability analysis and the formula of fuzzy probability measures for block stability are presented based on block theory and fuzzy measures theory. Furthermore, the method has been applied to analyze the block stability of roof in a caved area of Suichang Gold Mine in Zhejiang Province. Results show that the block tends to slide and safe measures should be taken before recovery of residue pillars at the caved area.更多还原
