ZDY-660 Mining Fully Hydraulic Tunnel Drilling Machine Fully Hydraulic Tunnel Drilling Machine

Description :

　　The ZDY-660 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.

　　The ZDY-660 mining full hydraulic tunnel drilling rig is mainly used for drilling gas drainage holes, grouting fire extinguishing holes, coal seam water injection holes, anti outburst and pressure relief holes, geological exploration holes, and other engineering holes underground in coal mines. Specially suitable for horizontal drilling of ± 30 ° underground in coal mines and allowing for all-round applicability of ± 90 °.

　　Main technical characteristics of ZDY-660 mining fully hydraulic tunnel drilling rig

　　1. The power head fully hydraulic combination drilling rig has a split structure, which is convenient for underground transportation, displacement, and installation.

　　2. The drilling rig is composed of hydraulic pump station, power head, frame, control console, column support and other components. It is connected by high-pressure oil pipes during operation and operated away from the borehole for safety.

　　3. The hydraulic system design is mature, simple, reliable, and easy to master, making it easy to analyze and solve faults when they occur.

　　4. Double column or four column support, one-time anchoring can drill multiple holes, light weight, high efficiency, and strong applicability.

　　Structural characteristics of ZDY-660 mining fully hydraulic tunnel drilling rig

　　The ZDY-660 mining fully hydraulic tunnel drilling rig is mainly composed of a pump station, a power head, a frame, a column frame, an operating platform, and drilling tools. The drilling rig pump station and power head are connected by high-pressure pipes of different diameters, and all joints are quick couplings, making installation, disassembly, and transportation convenient. The pump station is driven by an explosion-proof motor to rotate the oil pump, converting electrical energy into hydraulic energy (pressure oil) for the rotating oil circuit and propulsion oil circuit, and then delivering the pressure oil to the hydraulic actuator through the valve group on the control panel, thereby achieving various functions of the drilling rig.
