Abstract: Based on the problem of solving the low speed of rock tunneling in Huainan mining area, and according to the system theory and analytical structure model, the influence factors of rock tunneling speed were studied. The three-level impact factor index system of drilling and blasting method was established (8 in the first level, 39 in the second level and 72 in the third level). The system analysis relation diagram and the hierarchical factor chain of influencing factors were established, and the influence factor was also analyzed. It was found that the influence factors of drilling speed were different from each other and can be divided into three levels: surface, middle and deep, among which blasting technology, support technology, rock drilling equipment, sound and executive management system have the most significant impact on the speed of tunneling and cover the widest range. The results indicate that after applying the targeted measures, the rock tunneling speed in the Huainan mining area was significantly improved, and the drilling speed of the rock tunnel was up to 270 m/month, which means that the factor analysis result of the applied analytical model can provide significant guidance for the speed of rock tunneling.
