摘要
将围岩有关力学参数视为随机变量，以煤帮稳定极限状态为基础，应用工程可靠性理论，分析了回采巷道媒帮锚杆支护的可靠性，建立了可靠度计算模型，为优化回采巷道锚杆支护参数提供了一种新的方法。
Some mechanics parameters of surrounding rock masses are considered as random variables. Based on the stable limit state of coal wall, the coal wall bolting reliability of extraction gallery is analyzed by engineering reliability theory. The calculating model of reliable rate is established. The new method is supplied to optimize bolting support parameters of extraction gallery.
