SANDVIK DL2720―TOP HAMMER LONGHOLE DRILL RIGS
Sandvik DL2720 is a fully mechanized and compact electro-hydraulic top hammer longhole drill designed for underground mining in 3.2 x 3.2 meters or larger production drifts. It is capable of drilling vertical and inclined fans and single or parallel diameter 64 – 89 mm longholes up to 38 meters in length, using T38, T45 and T51 MF-rods or Ø65 mm tube rods. Sandvik DL2720 is mounted on a 4-wheel drive frame-steered and diesel powered carrier. It is equipped with HL820ST hydraulic rock drill, LFRC700 drilling module, FR10 longhole boom, VIC control system and FOPS operator’s safety canopy for high drilling capacity, good hole accuracy and maximum safety. The 360° drilling module rotation and wide boom swing and tilt angles make the drill suitable for most mining methods and various service support applications.
The layout of the Sandvik DL2720 undercarrier is designed for good visibility, mobility and stability, ensuring fast and safe tramming in narrow mine drifts. The operator’s canopy and maintenance interface are designed for easy access, safe operation and all service points are accessible from the ground level.
MAIN BENEFITS
AGILE DRILL
This drill rig is equipped with a compact carrier improving mobility. It offers fast and safe tramming and cornering in small drifts.
ROBUST DESIGN FOR CONSISTENT PERFORMANCE
The robust design and proven components of DL2720 ensure low operating costs and consistent performance, which increases productivity.
SAFER OPERATING CONDITIONS
The drill ensures ground floor accessibility of most of the daily service and maintenance points. Sandvik DL2720 has an operator’s canopy and maintenance interface designed for safe operation.
OPTIMIZED OPERATIONS
The 2710 class is the ideal solution for underground mines and drilling contractors looking for a smarter control of ore dilution and increasing selective process in mining. The series consists of three types of drills using a common platform for different applications.
• DD2710 for development drilling
• DS2710 for rock support bolting
• DL2710 and DL2720 for longhole production drilling
These drills are simple and safe to operate with robust components and provide an excellent performance to ownership cost ratio. Based on a modular platform, able to tram smoothly into mining and tunneling cross-sections of 2.7m x 2.7m or larger, this range of drills provide accurate drilling with high performance, a large coverage and drill capacity with enhanced product safety and excellent mobility.
EFFICIENT CONTROL SYSTEM
The VIC drilling control system features proportional collaring speed, allowing precise control during drilling operations. Anti-jamming technology is integrated to minimize disruptions and ensure smooth operation.
COMPACT AND VERSATILE LFRC700 DRILLING MODULE
LFRC700 is compact in size and allows the units to be operated in production drifts 3.2 m or greater in height and width.
HL820ST HEAVY HYDRAULIC PERCUSSIVE ROCK DRILL
Sandvik HL820T is equipped with a hydraulic stabilizer to control contact between drill bit and rock. This ensures optimal drilling performance with high drill steel life time.
