Product Details

## Overview The Kaishan KZ9 is a self-propelled open-pit DTH drilling rig designed for high-productivity blast hole drilling in quarries, open-pit mines, and large construction sites. As a member of Kaishan's KZ series, the KZ9 integrates a heavy-duty hydraulic rotary head, a chain feed system, and an on-board screw air compressor into a single tracked carrier. This self-contained design eliminates the need for a separate air supply, simplifies site logistics, and shortens setup time between holes. The rig is purpose-built for DTH (down-the-hole) hammer drilling in medium to hard rock, delivering straight, clean holes that improve fragmentation and reduce explosive consumption. ## Technical Features The KZ9 is powered by a 194 kW diesel engine that drives both the hydraulic system and the air compressor. The hydraulic top-drive head provides stepless rotation speed and torque control, allowing operators to match drilling parameters to changing rock conditions. A 4,500 mm feed stroke supports efficient single-pass drilling and fast rod handling. The tracked undercarriage offers excellent stability and a gradeability of up to 25 degrees, enabling the rig to work on steep benches and rough terrain. An ergonomic operator cab with joystick controls, adjustable seating, and good visibility reduces fatigue during long shifts. Centralized lubrication and easily accessible service points keep maintenance downtime to a minimum. The KZ9 is also equipped with a dust suppression system to meet modern environmental requirements on sensitive job sites. ## Applications The KZ9 is widely used in aggregate quarries, open-pit metal mines, limestone and granite operations, and infrastructure projects such as road cuts, tunnels, and dam construction. Its ability to drill 90–152 mm holes to depths of up to 30 meters makes it suitable for both production blasting and pre-split drilling. Contractors value the rig for its mobility, reliability, and low cost per meter in hard rock. In quarrying, the KZ9 helps achieve consistent bench heights and improved fragmentation, which lowers secondary breaking costs. In mining, it supports short- and medium-term production planning with dependable hole accuracy. For construction projects, the rig's compact footprint and self-contained design allow it to work in confined areas where larger rigs cannot access. ## Why Choose Kaishan Kaishan has been manufacturing rock drilling equipment for over 60 years, with a global service network and a strong reputation for durable, cost-effective machines. The KZ9 benefits from this experience through robust structural design, proven hydraulic components, and readily available spare parts. Whether you are drilling in a quarry in Southeast Asia or a mine in South America, the KZ9 delivers reliable performance and low total cost of ownership.

Working Principle

The Kaishan KZ9 operates on the down-the-hole (DTH) hammer drilling principle. A pneumatic hammer is attached to the bottom of the drill string, directly behind the drill bit. Compressed air, supplied by the rig's on-board compressor, is fed through the drill pipes to the hammer. Inside the hammer, the air drives a piston that strikes the bit at high frequency, typically 1,500 to 2,500 blows per minute. Simultaneously, the hydraulic top-drive head rotates the drill string, indexing the bit so that each impact fractures new rock. The air also serves to flush cuttings from the hole, carrying them up the annulus between the drill pipe and the hole wall. The KZ9's feed system applies controlled thrust to keep the bit in firm contact with the rock, while the rotation speed and feed rate are adjusted to match rock hardness. This combination of impact, rotation, and flushing creates fast, straight holes in medium to hard rock. The entire process is controlled from the operator cab, with joysticks managing tramming, positioning, and drilling functions.
