某矿回采顺槽掘进巷道因受地质条件及回采动压影响,在巷道掘进后出现强烈的底臌现象,强烈的底臌不仅带来了大量的维修工作,增加了维护费用,而且还影响了矿井的正常采掘衔接计划,为矿井安全生产带来了极大的安全隐患,通过对巷道底臌的形成机理及主要因素分析,提出了防治底臌的对应措施,取得了良好了经济技术效果。 Due to the influence of geological conditions and the dynamic pressure of mining, a roadway excavation along the tunnel led to a strong bottoming phenomenon after tunneling. The strong bottom not only brought a large amount of maintenance work, increased maintenance costs, but also affected the The normal digging and connecting plan of the mine brings great potential safety hazard for mine safety. Through the analysis of the forming mechanism and the main factors of the bottom of the roadway, the corresponding countermeasures for prevention and control are put forward and the good economic and technical results have been achieved.
