大埋深厚煤层综放工作面巷道支护技术研究

The Research of Coal Face Crossheading Supporting Technology in Large Buried Depth Thick Coal Seam

以山西天地王坡煤业有限公司王坡煤矿3316工作面回风巷支护为研究背景,分析了大埋深厚煤层巷道的支护原则和支护机理,通过现场布置不同支护方案位移监测点的方法,研究不同支护参数对顶板支护的影响,确定了王坡煤矿3316工作面回风巷的合理支护参数,现场应用效果良好,为该矿3号煤层其他工作面巷道支护提供了参考依据。

The paper is studies the background of 3316 working face crossheading supporting of the Shan XI Tiandi Wangpo coal mining co. ltd,the principle of supporting and supporting mechanism of large buried depth thick coal seam are analyzed,the method of the stress displacement monitoring point of different supporting schemes is arranged,the influence of different supporting parameters on roof support was studied,and the reasonable supporting parameters of the 3316 working face of wangpo coal mine were determined. The application of the site is well,and provides reference for the other working face of the No. 3 coal seam.
