Abstract：A low heading rate level of a mine rock roadway would have great influences to the construc‐tion and production of the coal mine.According to the judgement of the factors affected to the heading rate of the drilling and blasting method applied to the mine rock roadway was based on the qualitative as the main problem ,the heading construction with the drilling and blasting method could be divided into eight sections of hydrogeology ,rock drilling ,blasting ,support and others.The analytical hierarchy process (AHP) was applied to the quantitative judgement on the influence factors of the heading rate affected to the influence degree of the heading rate.The result showed that in the eight major factors of the heading rate with the drilling and blasting method applied to the mine rock roadway ,the main influence factors w ould be the blasting technology and efficiency and the second w ould be the organiza‐tion management and w aste rock discharging.
