In order to improve the tunneling speed of the mine roadway,based on the main factors affecting the tunneling speed,the optimal support row spacing of the roof bolt is obtained with the help of simulation analysis method.By improving and optimizing the cutting path of the roadheader,the optimal cutting path of the roadheader is found.By optimizing the working procedure,the operation mode that can implement multi procedure parallel operation is obtained.The practical application results show that after the comprehensive application of these efficient tunneling technologies,the mine support time can be shortened by about 16%,and the tunneling efficiency can be increased by more than 26%.At the same time,the surrounding rock of the supported roadway is more stable,which helps to better ensure the safe and efficient production of the mine.
