复杂顶板应力条件回采巷道支护技术
|
摘要
以复杂顶板应力条件回采巷道支护为对象开展研究,结合具体工程实际,借助数值模拟技术对无支护、锚杆支护和锚网索桁架支护3种形式下的巷道围岩变形情况进行了比对分析,并在此基础上对锚网索桁架支护的实际应用效果做了监测分析,希望能够为矿井生产的安全开展提供借鉴和参考。
Taking the support of mining roadway under complex roof stress conditions as an object of study, combined with the actual engineering, this paper compared and analyzed the surrounding rock deformation of roadway under three types of support, i.e.no support, bolt support and bolt-mesh-cable truss support, by means of numerical simulation technology. On this basis, the actual application effect of bolt-mesh-cable truss support was monitored and analyzed, hoping to provide reference for the safe development of mine production.
