Rock Dht Crawler Blast Hole Drill Rig for Mine
The down-the-hole drilling rig uses the impactor and drill bit that dive into the bottom of the hole to impact and crush the rock, so it is called a down-the-hole drilling rig. Widely used in metal mines, hydropower, transportation, building materials, harbors and engineering. Down-the-hole drilling rigs can drill holes in rocks with medium hardness or above (f≥8). The price of drilling rigs is relatively cheap, especially suitable for small and medium-sized open pit mines.
