摘要
二次互补支护最佳时间的确定是应用锚网索互补协同支护技术成功的关键之一。通过对大同煤矿集团轩岗煤电公司梨园煤矿2号煤层22110综放回采巷道掘进施工过程中的锚网索耦合支护时空问题的数值模拟研究,探索了二次互补支护时间的确定方法。现场效果表明,本文介绍的二次互补支护时间的确定方法有一定的工程参考价值。
The determination of the best second complementary support time is one of the successful keys to application of complementary and coordinated bolt-mesh-anchor support technology.By numerical simulation study on in the process of tunneling of No. 2 coal seam 22110 full-mechanized mining roadway in Liyuan Mine of Xuangang Coal Electricity Group Co.,Ltd. of Datong Coal Mine Group, the method to determine second complementary support time is studied.The field effect shows that this method to determine second complementary support time has a certain reference value for engineering.
