摘　　要：在对煤层巷道支护原理分析的基础上,针对某矿三软煤层巷道支护中遇到的问题,改变了原有的支护方式,提出了锚网与工钢棚联合支护技术,该支护技术的成功应用提高了煤层巷道的围岩强度和稳定性,为回采工作面的安全高效开采提供了保障。Based on the analysis of roadway＇s supporting theory in three soft coal layers, then combined support technology was proposed. Application results show that combined support technology improved the strength of soft rock tunnel and self-supporting capacity and the stability of surrounding rock, provided a guarantee for the mine＇s safety.
