详细说明
KAISHAN surface DTH drill rigs, equipped with powerful down-the-hole hammers, are designed for high-capacity rock drilling in surface mines. They are completely self-contained, with onboard compressors and efficient dust suppression. They are highly productive and very reliable, with low life-cycle costs.
Integrated hydraulic downhole drilling rig is widely used in metallurgical, mining, building materials, railway, hydropower construction, national defense construction and earth works, and the blasting hole drilling of open construction. It takes hydraulic drive for track traveling, rotary drill tool forward, drill tower top lifting compensation and drilling rig leveling. It takes compressed air from screw-type air compressors to impact drilling and flush the hole, with air pressure of 1.7MPa, and dry-type distribution laminar precipitator. The drilling tool takes high-pressure downhole impactor, with the drilling aperture of 90-115 mm, and the depth of 18 m vertical or inclined hole. It is the most advanced integrated hydraulic downhole drilling rig in China, with the feature of highly-efficient high pressure downhole drilling system, which facilitate to drill the blasted hole with high-precision and high efficiency. Global purchase, optimal design with the computer, power matching and the development and application of load applicable system contribute to the realization of the overall power load matching from power-pump -load in the power system, which effectively reduces the overall energy consumption and ensures the best performance and the overall high reliability.
