Development and Application of BMC 300 Raise Boring Machine

Based on the construction capacity of the domestic available raise boring machine was within the depth of 200 m,the machine volume was large,the big quantity was not suitable applied in the narrow and low mine roadway for the depth above 200 m,a BMC 300 raise boring machine was developed to bore a mine shaft within a depth of 300 m and suitable for construction in the mine roadway.The paper introduced the suitability conditions,technical parameters and application features of the raise boring machine.The good benefits were obtained from the application of the raise boring machine in the project practices.
