摘要
以河北金能集团东庞矿2610综采工作面巷道为背景,应用有限差分软件(FLAC)模拟巷道的开挖和支护,以围岩中锚杆和锚索不发生破坏为目标函数,对巷道支护方案进行优化分析。模拟结果表明,采用优化后的支护方案,能够使巷道围岩变形大大降低,围岩完整性增加。工程实践证明,取得了良好的技术经济效果,为煤巷支护优化设计提供了一种可行方法。
The process of coal - lane＇ s digestion and support are simulated by the two - dimensional finite - different computer codes （FLAC） on the ground of 2610 working place belonging to Dongpang Mining of Jirmiu Energy Corporation of Hebei and the design of support is optimized aimed at anchor rod or anchor cable in the surrounding rock unbroken. The simulation results showed that the plastic zone reduced largely and integrity of surrounding rock increased after applying optimum support parameters to coal lane. The actual project confirms perfectly that it is a feasible method in the support of coal mine and acquires very well effects of technology and economy.
