【摘要】 在现场监测的基础上,针对金源煤矿复杂构造条件下回采巷道稳定性问题进行研究。监测获得回采巷道受断层影响的变形与破坏规律,探讨了断层因素对巷道稳定性的影响,通过理论计算掘进及回采期间支架受力,分析得出回采期阐巷道支架上的栽荷是巷道掘进期间的6倍左右,巷道处于极不稳定状态,提出了调整巷道布置方案的安全措施。更多还原

【Abstract】 Based on the field monitoring,the stability problem of gateways under complex conditions of constitution in Jinyuan Coalmine was studied.The regulation of gateway deformation and damage influenced by faults was obtained by monitoring,and the influence of fault factors on the gateway stability was discussed.Based on the theoretical calculation of support stress state during mining and tunneling periods,the load on supports in gateway during mining period is about six times greater than that during tunneling period,as well as the safety measures for adjusting layout of gateways are proposed.更多还原
