摘要
以四川某铁矿缓倾斜中厚矿体为例,从切割、炮孔、爆破等方面系统地分析了无底柱分段崩落法开采缓倾斜矿体产生悬顶的原因及预防和处理措施。同时介绍了一些新颖的悬顶处理技术,为类似矿山提供参考。
With the gently inclined medium thick ore body in a mine of Sichuan as an example, causes for the generation of gently inclined ore body and its prevention and treatment measures are analyzed systematically in the areas of cutting, blast hole and blasting. Also, some novel technologies for treatment of hanging roof are introduced to provide a reference for the similar mines.
