Abstract: In order to solve the difficult support problem when mine roadway passing through complicated fractured zone, based on Kailuan Donghuantuo Mine as a study object, the pipe shield support technology of the mine roadway passing through the complicated fractured zone was conducted and a system of the pipe shield support technology was formed.A calculation method of the protection zone thickness above the pipe shield working room and the borehole pattern method of the pipe s hield were obtained.The results showed that with the coreless drilled dry concentric simultaneous casing dilling, punched pipe wall protection, high density grouting an d other comprehensive technology, outburst prevention drilling and stable pressurized grouting could be realized in the high water pressure, high geostress and easy m udding complicated fractured zone to provide a safety protection to the pipe shield support of the mine roadway.
