【Abstract】 On the base of integral function′s effect of the combined support of bolt and mesh ladder type of support. The mutual dependence′s relation of bolt length and the width of space and row is built. The previous combined beam′s design methods are improved. The new method has gained successfully application in actual bolting support of mining roadways with different conditions.更多还原
