深部厚大破碎矿体回采技术探讨

Mining Technology for Large Thick Broken Deep-Seated Orebodies

随着采矿工程的深部延伸,采矿环境变得越来越恶劣。对于深部矿产资源回采技术的研究成为了当务之急。而对于深部厚大破碎矿体的回采更是一个世界性的难题。以金川二矿区1#矿体为例,在采用机械化下向胶结充填采矿方法的基础上介绍了留矿柱两步回采方案跟无矿柱连续回采方案,并着重分析了各方案的优劣,这对类似矿山有十分重要的借鉴意义。

With the mining going deeper, the mining environment will become increasingly worse. It has become urgent to study the mining technology for deep-lying mineral resource and the extraction of large thick broken deep-seated orebodies is now a worldwide challenge. Taking the 1 ^# orebody in Jinchuan No. 2 mining section as the case, the two-step stoping scheme with pillars and the continuous stoping scheme without pillars based on the downward mechanized cementing back-filling method are introduced. Their advantages and disadvantages are analyzed, which can be of great reference significance to similar mines.
