安徽铜陵有色冬瓜山铜矿充填区井下-565 m中段5号盘区采场日前按期投入充填,目前共完成充填量2 200m。该采场的顺利填充,攻克了当前我国矿山大容量采场填充技术难题。该盘区采场总充填空间超过35万m3,由于暴露空间过大且位于岩石构造复杂的团山老区,充填作业存在破碎带渗漏等弊端,同时还存在大空间充填节奏调整、不同充填阶段采场泄压等技术难题。对此,该矿组织技术攻关,一举拿下《大容量采场钻孔标高测量与科学调整排放口最佳时间节奏》和《充填体上升高度与采场挡墙施工次序表》两项成果。该技术有效
Recently, the No. 5 panel stope in the middle section of -565 m underground in the filling area of Tongguashan Non-ferrous Dongguashan Copper Mine in Anhui Province has been put into filling on schedule. At present, a total filling volume of 2,200m has been completed. The smooth filling of the stope overcomes the current large-capacity mine field filling technology problems in our country. Due to the large exposed space and located in the old area of Tuan Shan where the rock structure is complex, there are some drawbacks such as leakage of broken zone in the filling operation. At the same time, there are large space filling rhythm adjustment, different filling stages Stope pressure relief and other technical problems. In response, the mine organized technological breakthroughs and won two major achievements: “the best time rhythm of large-capacity stope elevation measurement and scientific adjustment of discharge port” and “the order of height of filling body and retaining wall construction sequence”. This technique is effective
