厚煤层采动巷道支护技术研究

Application of Thick Coal Seam Mining-induced Drift Supporting Technology

介绍了厚煤层、破碎围岩巷道稳定原理及控制技术,并采用底角锚杆支护和高水速凝材料注浆加固技术对潞安环能股份公司王庄煤矿5211工作面的回风巷进行支护,从而提高动压沿空掘巷破碎区及塑性区围岩的强度,控制动压沿空掘巷围岩变形,为厚煤层动压、破碎围岩沿空掘巷围岩控制方法提供理论依据。

Mainly introduces thick coal seam, fractured surrounding rock drift theory and control technology, and the use of basic angle bolt supporting and high - water quick - setting grouting reinforcement materials technology in support of 5211 tailentry Wangzhuang coal mine at Lu＇an environmental energy development Co. , Ltd , thereby enhancing the strength of the dynamic pressure gob - side entry driving fractured area and the plastic zone surrounding rock, control deformation of dynamic pressure gob - side entry driving surrtounding rock, provide a theoretical basis for thick coal seam dynamic pressure ,fractured surrounding rock along gob -side entry driving control methods.
