摘要
针对寺河煤矿二号井一五三盘区回采巷道支护的难题,采取了理论分析、数值模拟及对实测数据分析的手段,通过对不同支护参数的比较,确定了最佳的支护方案。该支护方案能够有效地控制巷道围岩变形,在保证巷道围岩稳定性的条件下提高了巷道掘进速度,可为相似地质条件下的煤矿回采巷道支护设计提供参考。
In view of the difficult problem in the support of mining roadway in the 153 Pan Area of No.2 Shaft in Sihe Coal Mine,the best supporting scheme was determined by comparing different support parameters by means of theoretical analysis,numerical simulation and analysis of measured data.The support scheme can effectively control the deformation of roadway surrounding rock,improve the roadway driving speed while ensuring the stability of roadway surrounding rock,and can.provide a reference for the mining roadway supporting design under similar geological conditions.
