Development and Application of Complete Equipment for High-speed Tunnel Boring and Bolting Machines

Abstract

With the improvement of coal mining speed and mechanization level inChina, traditional tunnel boring methods can no longer meet the actualneeds. In order to solve the problems of low effciency, high labor intensity, slow tunnel boring speed, bad working environment and poor safetyin traditional tunnel boring, on the basis of analyzing the developmentand application of coal roadway tunnel boring equipment at home andabroad, complete equipment for high-speed tunnel boring and boltingmachines was developed by using the integrated technology of tunnelboring and bolting. The complete equipment for high-speed tunnel boring and bolting machines has the functions of tunnel boring and boltingsynchronization, once-tunneling, negative pressure dust removal, digitalguidance, independent cutting feed, digital cutting, safety monitoring anddata interaction, which has the advantages of safety in use, reliability andeffciency
