KQTG-150 Mining Down-the-Hole Drill Rig

The KQTG-150 mining down-the-hole (DTH) drill rig is a new type of DTH rock drilling equipment developed based on the actual application environment and site conditions of mines in China. It is mainly suitable for non-coal underground mines, tunnels, water conservancy and other geotechnical engineering projects. It can perform omnidirectional large-diameter deep-hole drilling, and is particularly suitable for drilling ring holes in underground stopes. It is a dedicated drilling equipment for high-sublevel mining methods, and can also be used for the excavation and stoping operations of raises and inclined shafts. The rig adopts a DTH impactor for operation, featuring a wide range of drilling diameters, deep drilling depth, high drill frame strength, and a drill frame capable of 360° rotation. It is equipped with a hydraulic operating mechanism and offers high drilling accuracy, effectively increasing the sublevel height of mines, and is particularly suitable for drilling ring holes in underground stopes.

Protective canopy cylinder, stable support, good rigidity, fatigue resistant.

Adaptable to different hole diameter operation requirements, adjustable rotation speed.

Front tilt 5°, rear tilt 90°

Adopts air cooling + water cooling dual cooling system

Two-stage rear axle steering travel system, flexible turning, dual-speed travel.

Adopts air cooling + water cooling dual cooling system

Closed-loop travel and in-situ steering system

Stepless speed regulation for propulsion and rotation

The entire machine adopts full remote control operation, keeping operators at a safe distance from hazardous areas and equipment, providing better visibility and greater operator safety. The operating handles are designed with a reasonable layout, making them easy to master and use. It is a fully remote-controlled self-propelled mining DTH drill rig. For long-distance movement, the braking mechanism of the travel reducer can be unlocked, and a trailer can be used to tow the drill rig.

Efficient DTH drilling system, easy to operate, reliable performance, high drilling efficiency, and good hole quality;

Compact structure, superior mobility and fast travel function, capable of in-situ steering;

The drill frame is equipped with a top support more suitable for working conditions, fully ensuring drilling stability and accuracy; the drill frame can rotate 360°, and stainless steel liner plates can be optionally installed according to customer requirements;

The entire machine is suitable for different rock hardness and different drilling diameters. The drilling diameter range is wide, and the drilling depth can reach 100 meters. The remote control model features stepless speed regulation for propulsion and rotation;

The optimal working height range of the machine in stopes and tunnels is 3.5-5.6 meters;

The drill rig's control console performs corresponding drilling operations through a remote electronic control console, making the construction environment safer.
