摘要
根据巷道矿压理论及数值模拟 ,得出平六矿丁 5、6 -2 2 1 3 0风巷窄煤柱护巷锚网支护合理煤柱宽度并优化了支护参数。矿压监测结果表明 :支护设计合理 ,巷道围岩变形在工程允许范围内 ,满足了安全生产需要 。
According to ground pressure theory and numerical simulation the suitable coal posts width of bolting with mesh for protection roadway of small coal posts is obtained in D5?6-22130 ventilating roadway of Pingdingshan 6th coal mine and support parameter is optimized. Themonitoring result of mine pressure showed that support design is suitable and satisfied the needs of safety in production, surrounding rocks deformation of roadway is within the limits permitted by engineering. And it has obtained good technical and economic benefits.
