摘要
针对阳煤二矿81107工作面走向高抽巷上覆砂质泥岩、细粒砂岩稳定岩层的特点,采用工程类比借鉴和现场实践结合的方法,研究巷道的合理施工路线、支护参数、掘进机截割路线等技术,巷道工程达到标准化巷道要求,主要工序耗时下降11.4%到13.6%,实现最快日进尺14.4 m,掘进速度大大提高。
According to the characteristics of sand mudstone and fine-grained sandstone stable rock strata on the high pumping roadway in 81107 working face of Yangmei No.2 Mine,the reasonable construction route,support parameters and cutting route of tunneling machine are studied by engineering analogy and field practice.The roadway construction meets the requirements of standardized roadway,and the main working procedure time is reduced by 11.4% to 13.6%,and the fastest daily footage is 1 4.4 m,the driving speed is greatly improved.
