Control Technology of Water Bearing Sandstone Roof in Return Air Roadway of 31102 Working Face

以31102工作面回风巷为工程背景,通过理论分析和现场实测,对含水砂岩顶板巷道控制技术展开研究。研究结果表明:含水砂岩顶板巷道的稳定性受到上覆含水砂岩顶板采动的影响,裂隙水与巷道围岩产生水-岩作用,围岩强度降低。研究结论为相同工程地质条件下巷道控制提供了参考和借鉴价值。

Based on the engineering background of the air return roadway in 31102 working face,the control technology of water bearing sandstone roof roadway is studied through theoretical analysis and field measurement.The results show that the stability of the roadway with water bearing sandstone roof is affected by the mining of the overlying water bearing sandstone roof,the fissure water and the surrounding rock of the roadway produce water rock interaction,and the strength of the surrounding rock decreases.The research results provide reference and reference value for roadway control under the same engineering geological conditions.
