Application of Non-pillar Medium-length Hole Breakdown and Explosive Force Transport Block Stoping Mining Method in Inclined Thin Veins
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.
