Practical Research on Transformation of Intelligent Control System for Tunneling Machines
The tunnel excavation technology in coal mines has gone through a development from blasting to mechanical excavation,and from mechanization to automation.However,there are still many shortcomings in the intelligence and technical level of comprehensive excavation machines in China.Among them,the intelligence level of the boom-type roadheader is relatively low,resulting in a low level of intelligent application of the comprehensive tunneling machine and other equipment in the working face,heavy construction operations,and safety hazards.Therefore,Dayang Coal Mine had decided to carry out intelligent transformation of the coal pillar working face in No.3 mining area and put the EBZ160i tunneling machine into use.This tunneling machine can achieve remote intelligent control,and at the same time,it can monitor the tunneling machine and heading situation in real time on the ground,relying on intelligent remote sensing technology to automatically shape the tunnel section.After production,the intelligence and mechanization level of tunnel excavation work can be significantly improved,with a single entry level of 290 m per month and a reduction of at least 50%in staff,resulting in a significant reduction in personnel and efficiency.
