摘要
利用赤平投影分析法分析西石门铁矿硅卡岩与蚀变闪长岩巷道受构造破坏而失稳的条件。认为采用喷锚支护是防止其初始冒落的有效措施。
The instability condition of the gallery located in the skarn and alteration diorite, which is caused by the structare damage, is analysed by analytical method of spherical projection. It is concluded that the shotcreting-bolting support is a effective measure guarding against initial caving.
