大佛寺矿40108综放工作面运输顺槽由于受综放工作面回采动压和周期来压的影响,顺槽顶板产生较大的变形,顶板支护强度不足导致运输顺槽整体变形严重,影响了安全生产。根据运输顺槽围岩破坏规律研究结果完成了运输顺槽修复支护方案设计和现场实施。现场监测结果表明,运顺的支护修复方案合理有效,抑制了运输顺槽围岩的进一步变形破坏,达到了预期的效果,保证了工作面安全回采。
Due to the influence of dynamic pressure and period pressure of fully mechanized top coal caving face in 40108 fully mechanized top coal caving face in DafuSi Mine, the deformation of the top deck of the fully mechanized top-coal caving face has a big deformation. The insufficient support strength of the top plate causes serious deformation of the whole trough, Safe production. According to the results of research on the failure rules of surrounding rock in the transportation channel, the design of the roadway repair and support scheme and the site implementation are completed. The on-site monitoring results show that YUNSHUN’s supporting and repairing scheme is reasonable and effective, which restrains the further deformation and failure of the surrounding rock in the transportation channel and achieves the expected effect, thus ensuring the safe mining of the working face.
