芦岭矿深埋多次采动巷道稳定性控制技术

    Stability Control Technology of Deep Buried Roadways Affected by Multiple Mining Activities in Luling Coal Mine

    • 摘要: 随着开采水平的不断延伸,芦岭矿开采重心逐渐向深部转移,矿井进入深部开采后,巷道在承受高地压的同时,大多数还要经受回采等引起的动压影响。在采动压力的作用下,原本趋于稳定的巷道往往出现大变形,难以维护等现象。因此,深埋采动巷道围岩稳定性控制成为制约芦岭矿安全高效开采的关键技术。

       

      Abstract: With the continuous extension of exploitation level, the mining activities in Luling Coal Mine gradually shift to the deep part. When the coal mine changes to the deep mining, the roadways have to experience the dynamic pressure influence caused by the mining activities as well as the high ground pressure. Under the action of mining pressure, original stabilized roadways usually appear huge deformation, and hard support problem. So the stability control of the roadway which is situated deep rock stratum and influenced by the mining activities is the key technology for the safe and high-efficient production of Luling Coal Mine.
