以淮南某矿1252(1)轨道顺槽底板巷道为研究对象,针对在强动压影响下原有支护方案无法满足后期留巷通风要求的最小断面问题,分析了1252(1)轨道顺槽底板巷围岩稳定性的影响因素,就该巷道在不同区段受采动影响程度不同的特点,提出了合理的加固方案。通过现场工业实验得到了理想的控制效果,并为该矿后续巷道支护及相近条件下巷道的治理提供了建议。
Taking the 1252 (1) orbital floor tunnel of a mine in Huainan as a research object, aiming at the minimum section problem that the original support scheme can not meet the requirements of ventilation in the retaining tunnel under the influence of strong dynamic pressure, the 1252 (1) The influencing factors of the stability of the surrounding rock in the floor are given a reasonable reinforcement scheme based on the characteristics that the roadway is affected by the mining in different sections. Through the field experiment, the ideal control effect is obtained, and the suggestions are provided for the follow-up roadway support and the control of the roadway in similar conditions.
