The cutting motor of mining-motor-cutting-type deep-hole drill is located in the bottom of the drilling. The motor rotates at the bottom of the drilling, with low noise and big drilling aperture. The drill pipe does’t rotate, only pushing forward; the back impetus is small, so as to save energy and reduce consumption.The maximum drilling depth is 200m. The radial error between the end to end of drilling is less than or equal to 200 mm.
