Research On Bolt And Mesh Reinforcement And Anchor Wire Coupling Support Of Mining Roadways In Ⅲ4303Working Face With Large Mining Height In ChangPing Mine

Many of China’s mining areas located around6.0m thick coal seam, Large miningheight fully mechanized coal mining technology has gradually become a new methodWhich is safe and efficient. The stability of large mining height fully mechanized coalmining face roadway has a crucial role in maintaining the mining’s high yield andefficiency. Roadway support question have been made many researches, and obtainedcertain research results, According to the specific conditions of large mining heightfully mechanized coal mining face soft rock roadway support problems but few studies,On the specific conditions of working face with large mining height under soft rockroadway supporting form and parameter research. The supporting form and parameterresearch on the specific conditions of working face with large mining height under softrock roadway which has great theoretical significance and practical value.This papers take Shanxi ChangPing mine limited liability company ChangPingmine as the research background based on survey of detecting losing circle of miningroadways and coal&rock mechnical parameters, rock stratum structure and geologystress survey result of ChangPing mine which are provided by ChangPing mine toanalysis large mining height working face roadway deformation characteristics,Influencing factors of the stability of roadways, instability mechanism of roadways.Research and exploration for ChangPing mine large mining height working face rationalsupport form and support parameters by theoretical analysis, numerical simulation, fieldtest and observation of mineral pressure combined method based on the perspective of‘coupling’.Last, make a industrial test in the ues of the supporting form and parameter toverify the rationality of roadway.The research results provides a theoretical basis and actual basis for the ChangPingcoal mining height working face roadway support and has a certain reference valueunder the similar conditions roadway supporting.
