ZDY-1200 Mining Fully Hydraulic Tunnel Drilling Machine

Description :

　　The ZDY-1200 mining full hydraulic tunnel drilling rig is suitable for drilling gas drainage holes in soft coal seams with a rock strength coefficient f ≤ 1.5, tunnels or drilling surfaces larger than 7m2, and heights greater than 2.8m underground in coal mines. It is an ideal equipment for drilling and draining gas from soft coal seams underground in coal mines, solving the problems of abnormal drilling and low hole formation rate caused by collapse, jamming, and clamping.

　　Product Features of ZDY-1200 Mining Fully Hydraulic Tunnel Drilling Machine

　　The ZDY-1200 mining fully hydraulic tunnel drilling rig has two types of drilling frames: column frame and seat frame. Different drilling frames can be selected according to the height and usage of the underground roadway in the coal mine. The drilling rig is equipped with a high-pressure water generator and uses high-pressure sealed drill rods to cut seams in coal seams with low permeability, thereby improving gas drainage efficiency and greatly reducing drainage time. This drilling rig adopts a hydraulic transmission mechanism, which has the characteristics of high drilling capacity, fast speed, simple operation, stable and reliable work, and easy movement and installation.

　　This type of drilling rig adopts a fully hydraulic structure, mainly composed of a pump station, a main engine, and an operation console. The joints connecting various parts of the drilling rig are all quick connect joints, which are easy to install, dismantle and transport; We mainly use hard alloy and diamond composite drill bits for rotary drilling, and can also be equipped with large-diameter spiral drill rods and coring drill bits to meet different drilling requirements.
