What is the efficient solution for mine blasting drilling?

In mining, water well construction, geological exploration and other engineering projects, drill rods are the core components connecting drilling rigs and drill bits. Their strength, precision and adaptability directly determine drilling efficiency, construction safety and service life. DRILLMORE focuses on the R&D and manufacturing of rock drilling tools, launching four series of drill rods for different working conditions, covering the full range of scenarios from shallow to deep holes, conventional drilling to reverse circulation operations, providing stable and reliable drilling support for engineering construction.

Tri-cone drill rods are the core power components of large drilling rigs, designed specifically for deep-hole drilling with high rigidity, strong impact resistance and long service life. With outer diameters ranging from 146mm to 273mm, they are compatible with various joint specifications from 4"BECO to 8"BECO, and the effective length can reach up to 10668mm. Made of high-quality raw materials with integrated heat treatment, the threads are precision-machined by CNC and inspected with professional gauges, ensuring tighter engagement and more stable torque transmission. They are widely used in large-scale drilling projects such as mines, water wells and geothermal energy.

Water well drill rods are tailored for water well and geothermal well development, suitable for operations at depths of 200-1500 meters. With outer diameters from 76mm to 114mm, they match standard joints such as API 2 3/8REG and NC26. The pipe body is made of high-quality fatigue-resistant steel, and the rod end is upset by medium-frequency heating to increase the welding area. After friction welding, tempering treatment is carried out to ensure weld strength. Featuring low rotation torque, small resistance and good sealing performance, they meet the requirements of both liquid and gas drilling, greatly improving the efficiency of water well construction.

Integrated mine drill rods integrate drilling and power transmission functions, suitable for full-hydraulic open-pit rigs, crawler DTH rigs and other equipment. Adopting integral forging or friction welding technology, combined with high-strength alloy steel and quenching and tempering heat treatment, they have excellent fatigue and impact resistance. With outer diameters from 64mm to 127mm, they support API standard and BECO joints, with effective lengths of 3000-6000mm. They are suitable for complex working conditions such as blasting holes, slope anchoring holes and geological exploration holes, and can operate stably for a long time in harsh environments.

Reverse circulation drill rods adopt an innovative dual-channel design, realizing simultaneous central slag discharge and annulus gas injection, effectively eliminating core contamination, sticking and loss problems. With a sampling integrity of over 95% and a 40% increase in drilling efficiency, they are the ideal choice for mineral exploration, geothermal and coalbed methane wells. With outer diameters from 89mm to 127mm, they are compatible with Remet and API standard joints, with customizable wall thickness and reliable inner and outer tube seals, greatly reducing construction costs and risks.
