Abstract: In order to solve the problem that the roadway is slower due to high ground stress and high mine disasters in the deep section of Hengyuan coal mine.Based on the analysis of the original tunneling technology of -960 m horizontal east wing track roadway, this paper obtains that the factors affecting the tunneling speed are geological objective factors and subjective factors of equipment personnel, then through the investigation of the new excavation technology and the geological conditions of the main road, this paper introduces the mechanized operation line of "CMJ2-30 hydraulic excavation drilling rig+ZWY-180/79L excavation loader+ST-8/6B shuttle truck", and uses medium and deep hole smooth blasting technology and strengthens the management of labor organization.The utilization ratio of blasting hole is increased to about 80% and the daily advance ruler is increased.From 1.6 m to 2.8 m, and in the four months from September to December 2018, a total of 354 m, with an average monthly advance of 88.5 m, has greatly accelerated the speed of roadway excavation and effectively alleviated the problem of mining imbalance in this mine.
