| 摘 要： | 根据锚杆支护理论进行锚杆支护设计,明确了应充分利用锚杆周围煤岩体自身的承载能力；以理论计算为主要依据,同时考虑工程类比和工程监测情况,在总结以往回采工作面支护效果的基础上,进一步优化设计,成功解决了大断面、全煤巷道的锚索网支护的技术问题,明确了全煤回采巷道支护参数和支护材料,为以后的类似巷道支护设计提供了重要参考依据；生产实践表明,设计的锚杆支护参数达到了预期效果,取得了良好的经济效益.

| Abstract: | Based on bolt support mechanism,the anchor bolt support design must make full use of the bearing capacity of surrounding rocks.By theoretical calculation and optimization design based on the support effect of coalface according to the engineering monitoring and analogy,the problem of bolt-mesh-cable combined support technology in large cross-section tunnels of coal seam is successfully solved.This solution also provide important reference for support design of similar tunnels by showing clearly support mate... |
