Construction of Coal Mine Roadway Excavation and Roof Support Technology
The excavation construction and roof support of coal mine roadway s are important links in coal mining.The importance,influencing factors and the existing research results were discussed by studying the roadway driving construction technology and roof support technology.In roadway excavation construction,fully mechanized excavation and large section continuous shearer excavation technology are the main research directions,while in roof support,bolt support,shed support,temporary support technology and reserved coal pillar support are usually adopted.Through the research and application of these technologies,the efficiency and safety of coal mine production can be improved.
