6 FAQs about [Portable down-the-hole drill price list]
What is down-the-hole drilling machine equipment?
The down-the-hole drilling rig uses the impactor and the DTH drill bits submerged into the bottom of the hole to impact and crush the rock. Therefore, it is called down-the-hole drilling machine equipment. YG DTH drill rig machine is widely used in metal mines, hydropower, transportation, building materials, harbors, and national defense projects.
What is down the hole drilling?
Therefore, they are called down the hole drilling. It is suitable for large-diameter blast hole drilling operations in small and medium-sized mines, road construction, water conservancy, and stone works, as well as for drilling bolt holes in slope support, tunnel support, and foundation pit support. The main drilling object is a rock formation.
What is down-the-hole hammer drill rig?
The working principle of the down-the-hole hammer drill rig is the same as other rock drilling rigs. It has the process of rock drilling and hole formation such as impact, rotation, ballasting, and advancement, and it belongs to percussion rotary drilling.
What is a DTH drilling rig?
The DTH drilling rig (down-the-hole drilling machine) is a kind of drilling machine, which is mainly used for drilling in rock formations. The down-the-hole drilling rig uses the impactor and the DTH drill bits submerged into the bottom of the hole to impact and crush the rock. Therefore, it is called down-the-hole drilling machine equipment.
What is the difference between a drill rig and a down-the-hole drill?
The difference is that the impactor of the down-the-hole drilling machine is installed at the front end of the drill rig rod, submerged into the bottom of the hole. And continues to advance as the drilling extends. Small outrigger-type down-the-hole drill rig (YGD70-80-100-120)
What are the different types of DTH drilling machines?
According to the different use environments, it is divided into two categories: open-air down the hole drilling rig and underground down the hole drilling rig. According to the way of walking, it can be divided into small outrigger type DTH drilling machine and crawler type DTH drilling machine.
