Abstract:
Aiming at the problems of low drilling efficiency, high labor intensity and low safety in the traditional blasting process of small section hard rock roadway in coal mine, a remote control drill for small section hard rock roadway tunneling was developed. The drill consists of a drill body and an electronic control system. The main engine, pump station, tracked vehicle and other parts of the rig body are integrated into one, with compact structure and small volume. The electronic control system includes control platform, remote control, control cabinet, sensors and electromagnetic starter, which can realize the remote control and condition monitoring of the perforation drill. Tests in the workshop show that the remote control perforation drill has reasonable layout, flexible operation, and can realize remote control and real-time monitoring of the drilling rig status, which provides a guarantee for greatly improving the perforation construction efficiency of small section hard rock roadway, reducing labor intensity and improving safety.
