深井地应力测量与运用分析

Measurement and Application Analysis of In-situ Stress of Deep Mine

文章介绍了套孔应力解除法进行地应力测试的方法,并应用此法对盛平煤业有限公司-630 m水平采区进行了地应力现场实测,根据5个地应力测站现场实测数据,得出了主应力与埋深、侧压比之间的关系,判定了应力量级,分析了背斜对地应力的影响。利用地应力分布特征对巷道布置方向及巷道两帮支护参数设计进行指导,确保了巷道稳定性,保障了安全生产,可为类似条件下矿井的安全开采提供参考。

This paper introduces the measurement of in-situ stress through stress relife method by overcoring, and measures the stress of -630m plane mining area of Shengping Coal Industry Co.Ltd. According to the data of five spots, the relation between primary stress and the buried depth and side pressure ratio is obtained, the impact of anticline is analyzed. The design of direction and support parameters of tunnel is guided by distribution characteristics of stress to make sure the tunnel is stable and safe, which provides reference for safe mining of similiar mines.
