AI Technical Summary
Existing mining technologies for medium-thick, stable ore bodies suffer from problems such as limited stope size, large amount of preparatory and cutting work, low production efficiency, and difficulty in balancing resource recovery rate and operational safety.
The step-and-pillar horizontal layered filling mining method along the strike is adopted, which includes the steps of stope division and structural parameter design, preparatory engineering layout, stope mining, rock drilling, blasting and ventilation and ore filling. By dividing the stope and pillars along the strike of the ore body, the number of connecting roadways is reduced. The bottom-up horizontal layered mining method is adopted, combined with pressure-drainage mixed ventilation and filling technology.
This has resulted in the expansion of the mining area, increased production capacity, reduced pre-cutting work, shortened mining cycle, improved resource utilization efficiency, and enhanced safety.
