摘要
为提高矿井支护的安全性能,考虑了矿井围岩与支护的随机性和模糊性等特点,采用结构可靠性理论论证回采工作面支护设计的安全性,建立了支护极限状态方程,并与安全系数法进行了对比分析。分析与实例计算显示,矿井支护可靠性分析是一种先进方法。
Aimed at improving the safety performance of shaft support, the paper introduces the use of the theory of structural reliability to prove the safety performance of supporting design in working face according to the characteristics of randomness and fuzziness of surrounding rock and shaft support. The paper gives supporting ultimate equation of state and highlights the comparative analysis of safe coefficient. The analysis and instances indicate that the fail-safe analysis of mine supports is an advanced method.
