文章详细介绍了大倾角三软厚煤层巷道支护参数的优化设计,并对支护效果进行数值模拟实验和工业性试验,通过现场应用,从根本上改善了支护状况,提高了支护效果,消除了诸多安全隐患,保证了安全生产,取得了比较好的经济效果。
In this paper, the optimal design of roadway support parameters in large soft coal seam with large soft seam is introduced in detail, and numerical simulation experiments and industrial experiments are carried out on the support effect. Through on-site application, the support condition is improved fundamentally and the support effect is improved , Eliminating many potential safety problems, ensuring safety in production and achieving relatively good economic results.
