Research and Application of High Extraction Roadway Excavation Technology in Working Face
Traditional high extraction roadway excavation has low efficiency and safety cannot be guaranteed.This article takes a coal mine working face high extraction roadway as an example,analyzes the support parameters and blasting methods,and adopts technologies such as combined support and full section one-time blasting to achieve efficient excavation of the working face high extraction roadway.The on-site practice effect is significant.
