%X 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.
