大进路无轨机械化联合充填连续开采新技术

New Continuous Mining Technology with Large Access Trackless Mechanized Combined Filling

结合云南驰宏锌锗股份有限公司会泽铅锌矿深部复杂难采矿体的开采,采用水压支柱护顶联合充填连续开采新技术对传统上向水平分层充填法进行了革新。以单体水压支柱顶板支护为技术核心,采用控制爆破技术,以及组合可拆式隔离墙施工技术和无轨机械化施工技术,扩大进路断面,加大废石充填量,实现了连续开采,确保采场顶板稳定,简化采矿工艺,降低采切工程量;进一步降低贫损指标,提高采矿生产能力。

In the mining of deep - seated complex deposit in Huize Lead - Zinc Mine of Yunnan Chihong Zinc - Germanium Co. , Ltd, the continuous mining technology with hydraulic - prop roof support combined filling was used to reform the traditional upward horizontal slicing filling method. With the roof support by monomer hydraulic props as its technical core, the method also adopts controlled blasting, combined detachable isolation wall and trackless mechanized construction technology, enlarged access section and increased waste rock backfill amount to realize a continuous mining. As a result, the stope roof stability is ensured, the mining process simplified, the cutting engineering quantities reduced, the dilution - loss further reduced and the mining capacity improved.
