Research on Turning Construction Technology of Fully Mechanized Roadway Complex Coal Seam
In response to the problems existing in the excavation process of complex coal seam tunnels,a certain coal mine was taken as the research object.The application of comprehensive excavation technology in different tunnels was analyzed from the aspects of turning radius calculation selection,model design implementation,etc.,providing reliable theoretical calculation basis for on-site operation.Through practical testing,the construction results showed that the theoretical and actual errors did not exceed±300 mm,improving the accuracy of excavation turning.At the same time,arranging the conveyor belt reasonably ensures normal slag discharge,reduces labor costs,reduces labor intensity,saves 2 000 yuan/person,and can achieve safe and fast excavation.
