Analysis of Blasting Technology for Large Section Rock Tunnel Excavation in Coal Mines
In order to further explore the excavation strategy of large section rock tunnels in deep mining of coal mines,this study takes the 2101 mining area of a certain coal mining enterprise as the research object.Combined with the current situation of insufficient excavation efficiency in this mining area,the blasting parameters are first theoretically analyzed and optimized.Then,the optimized parameters are applied for on-site blasting experiments to verify the excavation blasting technology scheme designed in this study.The results show that this technical solution has achieved relatively good technical indicators,proving that the solution has certain application value.
