Four Suggestions For The DTH Drilling Rig
Nov 28, 2017

As the use of DTH drilling rig is more and more widely used, how to use it safely is becoming more and more important.

1. ready to rock cavern, the cavern specifications can be perforated according to the method to determine the general level, digging Kong Shiqi cavern height is 2.6-2.8 meters, to cut down holes or inclined hole, hole Shiqi excavation width of 2.5 meters, a height of 3 meters.

2. to be used in the vicinity of the working surface, such as the steam water line, the lighting line and so on.

3. when the work started, it should be carefully checked whether the gas water pipeline is connected firmly, there is no leakage of water leakage phenomenon.

4. check whether the oil is filled in the injector.


DTH Drill is the impact rotary drilling rig, the internal structure and the general drilling machine is not the same, its valve and piston arrangement is independent, that is the impactor, but the rotary drilling rig is a kind of drilling equipment, more used in large open pit mine.

There are two kinds of pneumatic DTH Drill and the electric motor, wind power is relatively large, drilling depth is larger than the electric, electric equipment and small number of advantages is more suitable for transport at the site of weight. The drilling angle of the down the hole drill has changed from near zero to nearly 90 degrees. The drill rig is a geological drilling rig which is widely used in engineering investigation, though it can also adjust the angle of the head. But when the angle exceeds 45 degrees, it will be more difficult to drill.
