Coal Mine Roadway Excavation and Support Technology
During the operation of a mine,roadway excavation is a crucial step to ensure mine safety.In order to ensure the safety of coal mine roadway excavation,the characteristics of roadway support technology and mine production were elaborated,and some problems in roadway support technology were analyzed.The key points of the precautions for excavation and support construction in complex geological conditions were summarized.The segmented support measure for excavation roadway s was proposed,and the application effect showed that the support effect was good,which can provide reference for similar projects.
