Hydraulic Tunnel Coal Mining Drilling Rig In China

KDJ-200 coal mining drilling rig for mining with mechanical mast is mainly used for drainage, support and penetration-proof in tunnel for hydro-power station, highway, railway and coal mining, also in treatment disaster of dangerous rock and hillside and water well drilling as well, It is mainly suitable for drilling hard Rock with diamond and PDC bit, and DTH drilling as well.

Main features:

1. Mast with top-head, top-head driven by mechanical transmission;
2. Hydraulic cylinder make the top-head feed or feed back. Long feed stroke, drilling reliably;
3. The angle range of mast is adjusted by oil cylinder, good detachability, easy to maintain,
