Research on the Innovative Method of Coal Mine Roadway Protection Based on Aggregated Energy Blasting Roof Cutting
With the development of deep coal mining,roadway control has become an important part of the sustainable development of modern mines.In order to effectively protect deep roadways from the impact of dynamic disasters,an innovative method based on energy gathering blasting for roof cutting protection of roadways has been proposed.By combining theoretical analysis,numerical simulation,and field experiments,the control effect of roadway cutting based on energy gathering blasting was analyzed.It utilizes fragmented and expanded rock mass to support the old roof fracture structure,reducing the impact on the retained roadway.At the same time,the cutting method of the roof significantly improves the stress environment and effectively protects the roadway.The on-site test results have verified the effectiveness of the innovative method based on energy gathering blasting for roof protection of tunnels,and the convergence of the roadway was significantly reduced.
