Hard rock mining is no longer difficult Drilling operations in hard rock mining often encounter "bottleneck" problems: traditional Drilling Rigs are clumsy to move and can hardly move in concave and convex mines. When facing hard rocks above f8, the drilling efficiency is less than 0.5 meters/minute, which slows down the blasting progress. Are you worried about the equipment "breaking down" and delaying the work period, and high fuel consumption eating up profits? The crawler down-the-hole drill rig can be called a "tough guy in the mine". It is flexible and stable and is designed for hard rock mining. It conquers complex terrain with a crawler chassis, adapts to blasting holes and anchor holes of various metal and non-metal mines, and increases the efficiency of hard rock drilling to 1.2-2 meters/minute, allowing the daily footage to exceed 30 meters, and the construction period is compressed by nearly 40%. Product Features: Super strong passability: crawler ground pressure ≤…
