Application
Blast hole drilling rig is used most frequently in the mineral exploration industry among all the mining drilling equipment. This blasting rig is penetrating the rock via a air driven hammer and hammer bit. Its power supply comes from independent air compressor or on deck compressor or rock drill. The cuttings is blown out of hole by air It normally requires mining drill rigs have capacity of 15- 30m depth with 100 – 200mm blast hole diameter. Hard rock blast hole drill machine is dedicating to offer Mining Rigs with the latest and most advanced technology to ensure the most efficient of blast hole drilling and highest reliability. Our Blast hole drill is in various rod handling capacities, sizes, and angle drilling options. Known for excellent performance, efficiency, and low maintenance, our range finds application in mining and exploration industry.
Our Mining drill rigs are specifically designed for blast hole drilling to increase production and reduce down time. They are a modern versatile drill rig and come equipped with safety devices and ergonomics operating systems, it can guarantee that both safe and gets the job done properly without damaging a hole.
