红透山铜锌矿矿柱回采存在问题及措施探讨

Discussion on Problems and Measures of Pillar Mining in a Copper-Zinc Mine

红透山铜锌矿建矿60余年,井下开采深度达1200余米,日处理矿量2000余吨。深部-827 m中段以下至-1177 m中段系统建设正在进行中,未来2~3年采矿深度将超过1500 m。井下采矿工作由房采、柱采、切采及残采构成。但由于端部矿体呈窄、贫趋势,新增端部的房采采场无法对已结束的房采采场进行有效补充,而残采及切采比例有限,因此柱采产量对生产稳定起到至关重要的作用,从近年来的生产数据也反应出这一事实。本文就柱采采矿反映出的一系列问题及措施进行探讨。

The Hongtuoshan Copper-Zinc Mine has been in operation for more than 60 years,with an underground mining depth of more than 1,200 meters and a daily processing capacity of more than 2000 t.The construction of the system from the middle section of-827 m deep to the middle section of-1177 m deep is in progress,and the mining depth will exceed 1500 m in the next 2 to 3 years.Underground mining work consists of room mining,pillar mining,cut mining,and residual mining.However,due to the narrow and lean trend of the ore body at the end,the new house mining stope at the new end cannot effectively supplement the completed house mining stope,and the proportion of residual mining and cutting mining is limited,so the pillar mining output is stable for production.It plays a vital role and reflects this fact from recent production data.This article discusses a series of problems and measures reflected by pillar mining.
