Products Description
When encountering hard rock strata characterized by extensive jointing, standard single-boom drill rigs often prove inadequate; drilling progress is slow, and drill rod wear is accelerated. This dual-boom mining drill rig-from its power system to its structural design-is engineered specifically for "head-to-head" confrontations with hard rock, aiming to maintain high penetration rates even in the toughest geological conditions.

Dual Power Cores: Uninterrupted Operation
It features a dual-motor drive design (2 × 55 kW); even if one system experiences a minor fault or requires maintenance, the other system can continue to sustain basic operations, thereby significantly reducing the risk of a complete shutdown caused by power-related issues. The high-pressure hydraulic system delivers ample impact energy and rotational torque under hard rock conditions, ensuring the drill bit can effectively "bite" into the solid rock rather than merely "grinding" against it.
Comprehensive Coverage with Zero Blind Spots
It boasts an expansive working range, capable of adapting to roadway cross-sections ranging from 7.2 ×5.5meters up to 15 × 15 meters. The drill boom's wide pitch angle (+3° upward, -90° downward) and extensive compensation stroke allow it to effortlessly reach the very top and bottom of the working face-including drilling holes in the floor-without requiring the operator to exit the cab for manual adjustments. This "full-coverage" capability is particularly critical in hard rock tunneling, where denser drilling patterns are often required; fewer blind spots translate directly into more effective blasting results.
Working in hard rock environments, the greatest concerns are drill jamming and excessive tool wear. This rig's hydraulic system is equipped with an anti-jamming function; when sensors detect abnormal resistance, the system automatically reduces the feed rate and increases rotational torque, effectively preventing the drill rod from becoming "locked" within the borehole. Simultaneously, a high-pressure water flushing system (0.2–1.2 MPa) promptly flushes rock cuttings from the bottom of the hole, minimizing repetitive grinding of the drill bit against the rock face. This significantly extends the service life of both the drill bits and rods, saving you substantial costs on consumables.
Comprehensive Safety Protection
Mining environments are inherently complex; safety remains the absolute priority. The machine is equipped with a fully enclosed protective enclosure, effectively preventing rock fragments and dust from intruding into critical hydraulic components and electrical systems. The operator's console is positioned on the side of the machine body, offering an expansive field of view that allows the operator to clearly monitor the operational status of both drill booms, thereby preventing operational errors caused by blind spots. Capable of stable operation under standard mining voltages of 380V, the unit demonstrates exceptional adaptability.
This dual-boom mining drill rig serves as your "ultimate weapon" for accelerating progress and boosting efficiency within hard-rock tunnels, ensuring that every minute spent drilling generates maximum value.
