摘　　要：根据光道煤业20103运输顺槽软顶巷道实际条件,通过理论计算与数值模拟相结合的方法,确定其合理的锚杆长度为2.0 m,锚杆间距为0.9 m,锚索长度为6.3 m,锚索间距为1.6 m。现场应用结果表明,采用设计的支护方案后,巷道整体变形量较小,满足矿井安全高效生产需求。According to the actual conditions of the soft-roof roadway of the 20103 transportation gateway of Guangdao Coal Industry Co.,Ltd.,it was determined that the reasonable bolt length was 2.0 m,bolt spacing was 0.9 m,cable length was 6.3 m and cable spacing was 1.6 m by combining theoretical calculation and numerical simulation.The on-site application results showed that after adopting the designed support scheme,the overall deformation of the roadway was relatively small,meeting the requirements of safe and efficient production of the mine.
