In view of the problems of large workload of core drilling in mine adits, frequent transfer of drilling rigs and urgent demand for full hydraulic drilling rigs, in combination with the characteristics of core drilling in mine adits, a series of adit core drilling rigs are developed to improve the transfer efficiency, reduce the labor intensity of workers and improve the drilling efficiency. The drilling rig adopts platform design, with small overall size, light weight and compact structure, which is convenient for transfer under complex conditions in the roadway; Combined transportation scheme, suitable for transportation needs of non-coal mines; Development of large spindle through-hole, large torque and high speed, meeting the requirements of rope core drilling in complex formations; Add rod at the rear, independent of the length of the drill rod; Linkage control has high tripping efficiency and convenient operation, which can effectively prevent misoperation and tripping accidents; Convenient angle adjustment and wide adjustment range. It is a core drilling rig for coring and drilling at a depth of 800m, and meets the needs of geological survey, tunnel engineering survey, horizontal coring and drilling, and deep mine resource exploration and construction. At present, ZDY series tunnel core drilling rigs have been popularized and applied in batches in many mines such as China Copper Resources and Yunnan Gold.
