Abstract: Regard a coal as the research object, in view of the large mining height, enormous section and low advance rate, through comprehensive tunneling equipment upgrading, technology parameters optimization, production organization optimization to improve the efficiency and effectiveness of the excavation. Compared wtih the traditional excavation method, the advantages of the rapid excavation can be revealed in the following aspects: realizing mechanization supporting work, using CMM2-15C hydraulic drill carriage instead of MQT-120 pneumatic roof bolter and MQS-45 pneumatic hand-held anchor head, which can save the workers' labor and improve the efficiency and safety of the construction process. Supporting parameters optimization not only saves the supporting time, but also supporting materials. After using the rapid excavation technology, daily progress of roadway increased from 4.8m to 10.2m, through continuous detection about roadway roof after rapid excavation, find that roadway roof’s the biggest separated strata are less than the limit, roof stability and no roof falling risks. The successful application of rapid excavation technology, effectively save the construction time limit for a project, improve efficiency, and it plays a big role for high production and efficiency of the mine.
