Product Advantages
Fast Drilling Speed and Efficiency
Our Pneumatic Mine Rock Drill delivers high impact energy and frequency, enabling rapid drilling in medium to hard rock formations (rock hardness f=8–18).
Enhanced Reliability & Durability
Key components such as the piston and cylinder are manufactured from hardened alloy steel, ensuring long service life even under high-impact loads. The robust construction minimizes downtime and maintenance costs.
Wet Dust Suppression, Pneumatic Explosion-Proof
The Pneumatic Mine Rock Drill supports wet drilling and integrates a water injection system to effectively suppress dust and ensure a healthier working environment. Its compressed air power source eliminates the risk of explosion in flammable gas environments.
Drilling Direction Flexibility
The Pneumatic Mine Rock Drill is made for drilling up and overhead. The Pneumatic Mine Rock Drill can drill at angles from 60° to 90° which makes the Pneumatic Mine Rock Drill perfect for jobs like stope and rock bolting and raising, in underground spaces.
Structural Features
The product is made in a way that makes it easy to take apart and put back together. The air-leg mechanism is a part of this product and it has a strong aluminum cylinder that helps it move up and down smoothly. The whole thing is pretty small and it is balanced well so it is easy to move in tight spaces underground. All the parts of the product are made to work in a simple way so you can switch them out quickly and you do not need to keep a lot of extra parts on hand.
Production and supply capabilities
Monthly production capacity
Under normal conditions, the monthly production of a single model of pneumatic mining rock drilling rigs can reach 600-800 units, and the production line can be flexibly adjusted according to orders.
Delivery Time
Standard models can be produced and shipped within 15-20 days after receiving the prepayment.
Inventory Guarantee
300-500 units of commonly used models are maintained in stock to meet the 3-5 day shipping needs of urgent projects.
Supporting Accessories
Original drill rods, drill bits, oilers, and other accessories can be provided simultaneously and shipped with the main unit, eliminating the need for customers to purchase them separately.

Frequently Asked Questions (FAQ)
Q: What is the main advantage of your Pneumatic Mine Rock Drill, such as the Mining Stoper Drill?
A: The primary advantage is itshigh drilling speed and reliability. TheMining Stoper Drillcombines strong impact energy with a robust design, ensuring efficient performance in challenging rock conditions with minimal downtime.
Q: Can the Mining Stoper Drill be used for horizontal drilling?
A: While optimized for upward drilling (60°–90°), theMining Stoper Drillcan be adapted for near-horizontal applications with proper support equipment. For primarily horizontal drilling, we recommend our YT28 series pneumatic leg rock drills.
