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

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.
