What types of DTH rigs are there?

Commonly used models: YQ-80, YQ- 100, QZ- 165.

The essence of down-the-hole drilling is to make the impactor dive into the hole during drilling, so as to reduce the energy loss caused by the impact work transmitted by the drill pipe, thus reducing the influence of hole depth on drilling efficiency. DTH drilling company's drilling equipment is DTH drilling rig. In China, YQ-80, YQ- 100 and QZ- 165 are commonly used models in underground mines.

For example, the appearance of YQ- 100 DTH drilling rig consists of slewing mechanism, lifting mechanism, propelling mechanism, supporting mechanism and impact mechanism. ?

Precautions for use:

1. Prepare the drilling cavern, and the specifications of the cavern can be determined according to the drilling method. Generally, when drilling horizontal holes, the height of the cavern is 2.6-2.8m, and when drilling upward holes or inclined holes, the width of the cavern is 2.5m and the height is 2.8-3m.

2, gas pipeline, lighting lines, etc. Stand by near the working face.

3, according to the requirements of the mouth of the cave design, the pillar set up firmly. The upper and lower ends of the column should be padded with wooden boards, then the horizontal shaft and snap ring should be installed on the column at a certain height and direction, the machine should be lifted by hand winch, fixed on the column at the required angle, and then the hole direction of the drilling rig should be adjusted.
