Down-the-hole drilling rig is a device used to drill (install in the drilled hole) in the rock or soil layer before drilling the project.
Widely used in large, medium and small mines, hydropower, transportation and other earth and stone excavation and blasting projects, coal mine roadway support projects, deep blastholes for mining vehicles, etc.
The down-the-hole drill is designed according to the characteristics of roads, railways, water conservancy, hydropower, mine construction and other projects. The roads are inconvenient at the beginning of construction, and the lifting and transportation equipment cannot directly transport the equipment to the construction site. Most people can only enter the site by pulling their shoulders. One of the lightest down-the-hole drills, which can reduce the weight of the host to a large extent, but can still meet the needs of users for digging larger holes. It is also suitable for slope anchoring, digging patios and ventilation holes, etc., and can also be used for underground mining operations. Because this machine does not have an explosion-proof function, it must not be used in underground mines with gas.
