KQTG-150 hydraulic DTH drilling rig is a new type DTH drilling equipment developed to actual application. It is mainly used in non-coal underground mines and tunnels, water conservancy and other geotechnical engineering. It can carry out all-round large diameter deep hole drilling, especially for circle drilling in underground stope. It is a drilling equipment for high sub-level mining, and can also be used for excavation of service shaft or inclined shaft.

The rig uses DTH hammer with large range drilling diameter, deep drilling depth and strength drilling frame which can make 360°(-90°, 270°) rotation, and with a hydraulic stabilizing rod mechanism for high drilling accuracy, that effectively improved sub-level height, suitable for circle hole drilling underground.
