Product Details

## Overview The Kaishan KT9D is a track-mounted open-pit DTH drilling rig designed for demanding blast hole drilling in mining, quarrying, and construction. As part of Kaishan's proven KT series, the KT9D integrates a powerful diesel engine, high-torque hydraulic rotary head, and advanced dust suppression to deliver efficient penetration in medium to hard rock. It is engineered to drill 90–165 mm diameter holes to depths of up to 30 meters, making it ideal for production drilling in open-pit mines and large quarries. ## Technical Features The KT9D is built on a heavy-duty tracked undercarriage for stable tramming on rough terrain. Its hydraulic system provides smooth, precise control of feed, rotation, and tramming, while the high-torque rotary head ensures reliable torque transmission even in challenging formations. The rig features a powerful Cummins diesel engine that meets emission standards and delivers consistent power for both drilling and travel. An integrated two-stage dust collector with water injection significantly reduces airborne dust, improving visibility and compliance with environmental regulations. The ergonomic operator cab offers excellent visibility, adjustable seating, and intuitive joystick controls, reducing fatigue during long shifts. Maintenance points are centralized for quick access, minimizing downtime. ## Applications The KT9D excels in open-pit mining for iron, copper, gold, and coal, where it drills blast holes with high accuracy and speed. In limestone and aggregate quarries, it delivers consistent performance for production drilling. It is also suitable for construction sites requiring rock excavation, such as road cuts, foundations, and tunneling portals. Additionally, the rig can be used for water well drilling in unconsolidated formations when equipped with appropriate tools, though its primary design is for DTH blast hole drilling. ## Why Choose the KT9D With its combination of power, reliability, and low operating cost, the Kaishan KT9D offers a compelling solution for contractors seeking a versatile open-pit drilling rig. Kaishan's global service network ensures prompt support and genuine parts availability, maximizing uptime and return on investment.

Working Principle

The Kaishan KT9D operates on the down-the-hole (DTH) drilling principle. A pneumatic hammer is positioned at the bottom of the drill string, directly above the drill bit. Compressed air is delivered through the drill pipe to drive the hammer's piston, which strikes the bit with high-frequency impacts. Simultaneously, the rotary head turns the drill string, indexing the bit for efficient rock breakage. The feed system applies optimal thrust to maintain bit-to-rock contact, while the air flow also flushes cuttings from the hole. This combination of impact and rotation achieves high penetration rates in hard rock. The KT9D's hydraulic system controls feed, rotation, and tramming, ensuring smooth operation. An onboard compressor provides the necessary air for the DTH hammer and hole cleaning. Dust is suppressed by a water injection system and collected by a two-stage filter, maintaining a safe and clean worksite.
