广西高峰矿业公司深部矿体采矿方法的改进

根据高峰矿业公司100号矿体深部矿段的赋存特点和开采技术条件，提出了一种改进的采矿方法，即预控顶机械化分段充填采矿法，该方法沿矿体走向划分矿块，矿块内按10m高的分段用上向中深孔爆破落矿，并且对分段拉底空间用喷浆或锚杆支护。该采矿法的采矿效率高，回采作业安全性好，简化了充填工序，降低了生产成本。

A Modification on the Mining Method for the Deep Orebody in Guangxi Gaofeng Mining Ltd

Based on the occurrence characteristics and mining technological conditions of deep zone of the No.100 orebody in Gaofeng Mining Ltd., a modified mining method is proposed, that is, the Pre-Roof-Controlled Mechanized Sublevel Mining with Backfill. According to the method, blocks are divided along the strike of the orebody, and in a block, 10m high sublevels are fragmented through upward medium-length hole blasting. Undercutting is performed for each sublevel, and mined-out space is supported through grouting or bolts. The modified mining method offers high mining efficiency and excellent stoping safety performance, simplifies filling procedures and cuts operational cost.
