强动压影响下轨道顺槽底板巷道加固技术研究

Research on Reinforcement Technology of Track Crossheading Floor Roadway under Strongly Dynamic Pressure

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) track crossheading floor roadway of a mine in Huainan as the object of study. According to the original support scheme under the dynamic pressure cannot meet the trouble of minimum cross-section acquired by the gob-side entry retaining and ventilation in the late period. By analysed the factors influenced the stability of surrounding rock of 1252(1)track crossheading floor roadway. And put forward a reasonable scheme for reinforcement on the analysis of its different section suffering from different degree of mining influence. Also, the Colliery have got the ideal control-effect through the industrial experiments on the spot, and provided advice for subsequent roadway support and governance under similar conditions of the mine.
