摘要
针对齐家沟分矿倾斜薄矿脉,深部矿体倾角变缓的特点,通过对中深孔落矿爆力运搬阶段矿房采矿法在倾斜薄矿脉中的研究与试验,解决倾斜薄矿体放矿困难、矿块生产能力较低的实际问题,拓宽了中深孔阶段矿房采矿法的应用范围,为中低品位的倾斜薄矿体在增加产量、解决放矿问题、提高经济效益方面提供了一种可能.
Abstract
Based on the characteristics of the gradual slowing dip angle of the deep ore body in the inclined thin vein of Qijiagou mine,the application of medium-length hole breakdown and explosive fore transport block stoping mining method in the inclined thin vein is studied.It solves the practical problems such as difficulty in ore drawing for inclined thin ore bodies and low production capacity of ore blocks,broadens the application scope of the medium-length hole breakdown block stoping mining method,and provides a possibility for increasing production,solving ore drawing problems,and improving economic benefits for medium-low grade inclined thin ore bodies.
