The Maximum Drilling Depth Of This Tunnel Drilling Rig

It is this hydraulic drilling rig for coal mines. The maximum drilling depth hits the kilometre. In the video, the ZDY10000L waiting for delivery is a crawler fully hydraulic tunnel drilling rig for coal mines. Compared with the light general-purpose drilling rig ZDY2300L for shallow hole foundation operations with a hole of 100-300 metres, the ZDY15000L ultra-deep hole directional record model has a measured hole depth of more than 1,300 metres.

The ZDY10000L is located between medium and ultra-deep vias, balancing cost and performance. It belongs to the main model of deep hole orientation and is suitable for 800-1000 drilling construction. Dimensions: length, width and height are 4100*1050*2050. The minimum working height is 1.4 metres. It is equipped with a high-power motor; the rated power of the pumping station is 90 kilowatts. The output torque can reach more than 10000 Nm and the feeding force is as high as 210 kN. It can drill into complex rock formations with a rock solidity coefficient of f≤10 in soft coal seams.

Combined with the wind slag discharge process, the spray holes can be greatly reduced, preventing stuck drilling and other accidents. Compared with the international competitor VLD-1000 drilling rig, the ZDY uses a host with a pumping station control table featuring a three-part modular split design. It can also be further disassembled, making it convenient for transportation and installation in narrow underground spaces. It is more suitable for the complex roadway conditions of domestic coal mines, and the accessories and maintenance costs are low. The used mines are all good, and I also recommend you give it a try.
