Design and Optimization of Fault Support Scheme for Coal Mining Face Excavation Roadways
This paper mainly focused on the optimization of fault support schemes for coal mining face excavation roadways.Firstly,it provided an overview of the causes and methods for the formation of roadway faults.Secondly,taking 13102 working face of a coal mine as an example,it provided a detailed description of the application of the original support design for roadway faults,analyzed the insufficient support,proposed optimization plans for temporary and permanent support,and explored the application effects of optimized support.The results show that the phenomenon of stress manifestation in the surrounding rock of the fault area has been significantly improved,ensuring the safety of tunnel excavation.
