ZDY Underground Jumbo Drill

Description
ZDY coal mine hydraulic underground drilling rig is newly developed equipment by Lanxiang. A whole set of ZDY underground jumbo drill is composed of main engine, pump station and console. This full-hydraulic drilling rig is mainly applied in underground coal mine for drilling gas drainage hole, outburst prevention hole, fire-fighting grouting hole, coal seam water injection hole, geological exploration hole, etc.

Features
1.We use high pressure sealed drilling pipe and bottom hole motor, which can greatly promote drilling ability of the underground jumbo drill.
2.We have two kinds of drilling stands, including stand column frame and seat frame, for your selection.
3.This underground drilling rig can cut coal seam of low permeability when equipped with high pressure water generator and optional high pressure seal drill pipe. In addition, it improves efficiency and decreases time of gas drainage.
4.Configured with hydraulic actuator, this underground jumbo drill has features of strong drilling power, fast drilling speed, easy operation, reliable performance, high safety, etc.
5.The main engine is of split type structure, which can be disassembled for the convenience of transportation.
6.It can be configured with hard alloy or PDC drill bit for rotary drilling. Besides, it can be equipped with large-diameter spiral drill rod and coring bit according to your different drilling requirements.
