The ZMK5530TZJF120 remote electro-hydraulic control truck mounted drilling rig, independently developed by CCTEG Xi'an Research Institute was successfully tested in Meihuajing Coal Mine. The 120T lifting power drilling locomotive adopts remote electro-hydraulic control technology, which can realize the change of drilling operation from manpower participation to manual control, and reduce the labor intensity of workers while improve the safety operation level. At present, the 624m well construction has been successfully completed, and the reaming drilling is progressing smoothly.
