摘要
根据厚锚固板理论优化了古书院煤矿15#煤层盘区轨道巷和盘区回风巷锚固支护方案,定量确定了锚固支护参数;对厚锚固板结构支护条件下的巷道矿压显现过程进行了现场观测,结果显示,巷道变形量明显减小,取得了良好的支护效果。
According to the thick anchor plate theory, the paper has optimized the anchoring support scheme of the panel track roadway and ventilation roadway in No. 15 coal seam of Gushuyuan coal mine, and made the quantitative determination of the anchorage support parameters it also has conducted the in-situ observation on the roadway strata behavior under the supporting condition of the thick anchor plate structure, and the results show that roadway deformation decreases obviously and the support effect is good.
