摘要
针对云南某铅锌矿研究应用“架箱支护机械化强采强出”联合“双钻孔找顶排气强充”技术。应用证明,该技术主动对松散矿岩采用膏体进行置换,可消除原采矿方法面临的岩砂层内冒顶风险,整体降低岩砂层回采作业的安全管理难度,且矿块回采能力也得以提高。
The united technology of“frame box support for mechanized mining”and“borehole technology dual top exhaust charging”is applied on one Yunnan lead-zinc ore.The results show,the loose ore rock was replaced by paste by using of the above mentioned technology,so the roof fall risk of the sand rock layer can be eliminated,the overall difficulty of safety management of sand rock layer stoping operation can be decreased,and the ore mining capacity can be improved.
