Open-pit mining processes mainly involve drilling, blasting, mining, transportation and dumping. Drilling is the first process, costing 10% to 15% of the total cost of open-pit mining.

DTH drilling rig enables flexible drilling angles to ensure quality of ores and break large rocks into smalling cuttings to improve blasting efficiency. This type of surface drilling rigs features flexibility, light weight, high cost-effectiveness and increased drilling efficiency. It is particularly applicable to medium-hard rocks. Thanks to its advantages, it is widely used for small and medium-sized mines.

JK Drilling provides a wide range of DTH drilling rigs that adopt Atlas Copco two-stage air compressors with strong output. The rigs are suitable for rocks of different hardness and they are efficient, energy-saving and environmental-friendly.
