采用理论分析和现场试验相结合的研究方法,总结了火成岩侵入影响的特厚破碎煤层全煤巷道的变形和破坏特征,提出了采用高强度高刚度的锚杆锚索支护系统进行巷道支护设计,井下施工实践证明,这种方法技术经济效益显著,有效地提高了巷道的安全程度。
The method of combining theoretical analysis and field test is used to summarize the deformation and failure characteristics of coal seam gateway in the thick and broken coal seam affected by igneous intrusion. Proposed the use of high strength and high rigidity bolt and anchor cable support system for roadway support Design, downhole construction practice has proved that this method is significant technical and economic benefits, effectively improve the safety of roadway.
