The YSJZ series shaft drilling rig is a specialized mechanized rock drilling equipment developed by our company for the expansion of small-diameter vertical shafts in iron ore and non-ferrous metal mines.
The rig has strong power and adopts hydraulic transmission, with all movements mechanized. The drill rod positioning is rapid, accurate, and stable, and it is equipped with high-performance rock drills, achieving high drilling efficiency.
Energy Saving
For low-grade products, the power required by the electro-hydraulic system is only 1/3 of the power consumption of pneumatic drilling, and it can provide small power, thus saving energy.
High Drilling Efficiency and Fast Speed
Through experimental comparison, under the same rock conditions and the same hole diameter, the drilling speed of hydraulic rock drills for deep holes is more than 2 times higher than that of pneumatic drilling, and the hydraulic drilling speed can reach 0.8-1.5 m/min.
Improved Construction Quality
Since hydraulic drilling can ensure the precision of drilling depth and spacing, it can improve the construction quality of the project.
Lower Operating Cost
Since hydraulic drilling parameters are adjustable, the optimal drilling parameters can be selected under different rock conditions. The hydraulic drilling impact pressure wave is smooth and the transmission efficiency is high, so drilling tools and rods can generally save 15-20%. The hydraulic pressure is about 10 times higher than the pneumatic pressure, so at the same impact power, the hydraulic rock drill piston has a smaller stressed area, less power transmission loss, uniform stress, long service life, and fewer faults, so the cost is about 30% lower than the same.
Improved Working Environment
Since hydraulic drilling does not need to exhaust waste gas, there is no environmental pollution caused by oil stains mixed in the waste gas. The visibility of the working face is improved, and the operating environment is improved. Hydraulic drilling can reduce noise, and can reduce pneumatic drilling noise by 5-10 decibels.
