Integration Transformation and Application of Rock Tunnel Synthesising Machine Digging,Anchoring,Protecting and Exploring
Gaozhuang Coal Company has improved and designed the EBZ260M-4 type digging,anchoring,protecting and exploring machine based on the EBZ260 roadheader,which can complete the process of cutting,loading,conveying and other processes,as well as the installation of anchor rods and anchor cables,temporary support,and the construction of water holes,which realises the mechanization of the work of anchoring and protecting and improves the safety coefficient.The integrated machine for digging,anchoring,protecting and exploring has been tested industrially in the bottom pumping lane 502 under 3,and the average footage has been increased from 3.4 m/d to 5.1 m/d,which is an increase of 50％,and the speed of the digging operation has been greatly improved.
