西曲矿2~#煤复合顶板动压影响下支护技术研究
|
摘要
以西曲矿南三盘区2~#煤复合顶板动压影响下12313工作面回采巷道支护为实际工程背景,综合采用理论分析、数值模拟和矿压监测的研究方法,对12313工作面回采巷道的合理支护参数进行研究,取得了良好的经济技术效果,保证了复合顶板动压影响下2~#煤工作面安全高效生产。
The roadway support of No.12313 working face is influenced by dynamic pressure from compound roof on No.2coal seam in South Panel 3of Xiqu Mine.Taking the support as engineering background,theoretical analysis,numerical simulation and mine pressure monitoring were integrated to study the reasonable supporting parameters,which has achieved ideal economic and technical effects and could guarantee safe and efficient production of No.2coal working face under the dynamic pressure from the compound roof.
