Optimization and Application of Mining Methods for a Steep Inclined Thick and Large Ore Body
Steeply inclined thick and large ore bodies are one of the common forms of ore bodies in underground mining.A certain gold mine originally used the segmented open pit method to open the steeply inclined thick and large ore body in the mining area.With the deepening of mining and the deterioration of surrounding rock conditions,it is urgent to explore safer construction opera-tions and higher production capacity mining methods.In view of this,this article proposes the panel room column alternating rise lo-cal non roof filling mining method,and discusses in detail the mining process of this mining method.Combined with on-site indus-trial experiments,it is shown that the new mining method not only significantly improves the degree of mechanization equipment in the mining area,but also focuses on reducing the ore loss rate by 67.62% and the ore dilution rate by 45.07%,reducing resource waste and achieving significant economic benefits.It can provide reference for the mining of similar steep and thick ore bodies.
