摘要
自然崩落法采矿工艺在铜矿峪矿5#矿体810中段成功应用,没有产生大范围的地压活动。690中段投产两年后,出现了大规模的地压灾害,造成很大损失。本文对铜矿峪矿690中段地压显现的原因进行分析,希望给地压灾害预防提供参考。
Natural caving technology applied successfully in No.5 orebody 810 level of Ton-gkuangyu mine, and haven't produce large gr-ound pressure activity. After 690 level put into production two years, large-scale ground disa- ster appears, and heavy losses are sustained.In this paper the reasons for the ground pressure appearance of 690 level in Tongkuangyu mine are analysed. It is hoped that gives reference for ground disaster protection.
