摘　　要：隧道开挖多采用钻爆法,可以分段开挖,加快工程进度,与全断面法(使用TBM时)相比施工成本低。钻爆法出渣作业中需要使用高效的挖装机。通过对隧道挖装机双动力的匹配技术、工作装置的有限元分析技术、负荷传感液压系统技术、电控风扇冷却系统技术、电控系统技术等进行研究,完成样机试制,经工业性使用试验,表明产品达到了国内领先水平。Drill and blast method is commonly used in tunnel construction.The cost of drill and blast method is lower than that of TBM method.Efficient tunnel heading and loading machine is needed in mucking when drill and blast method is adopted.Study is made on the double power matching technology,the working device FE analysis technology,the load sensing hydraulic system,the electric fan cooling system and the electric control system of the tunnel heading and loading machine.A prototype of the tunnel heading and loading machine is developed.The commissioning of the machine demonstrates that the machine has reached the domestic leading level.
