Chongqing Inca Rock Machinery Launches Handheld Rock Drills for Underground Mining
Chongqing Inca Rock Machinery Co., Ltd. has recently introduced a new generation of pneumatic handheld rock drills specially designed for underground mining and tunnel excavation. With core advantages including light weight, high efficiency, safety, reliability, durability and energy saving, the product provides a superior rock drilling solution for underground mining projects worldwide.
Core Technical Advantages
Lightweight & ergonomic design
Weighing only 24 kg, the drill features a compact structure and reasonable center of gravity, equipped with anti-slip and shock-absorbing rubber handles. It greatly reduces labor intensity and allows single-person flexible operation even in narrow mine roadways and remote stopes.
High impact power & fast drilling
Adopting an optimized pneumatic distribution structure and precision piston components, the drill delivers stable impact frequency and strong impact energy. Suitable for standard bore diameters of 34–45 mm and maximum drilling depth up to 5 meters, it improves drilling efficiency by more than 15% compared with similar models in medium-hard and hard rock conditions (f=8–18).
Intrinsic safety for mining applications
Purely pneumatic drive produces no electric sparks, fully complying with explosion-proof safety standards for underground mines with gas and flammable dust environments, ensuring maximum safety for personnel and equipment.
High durability & low maintenance cost
Key components such as cylinders, pistons and valves are made of high-strength alloy steel with precision heat treatment for excellent wear resistance. The modular design enables easy disassembly and maintenance, with highly interchangeable wearing parts, reducing downtime and operating costs.
Energy-saving & wide adaptability
Optimized air path design reduces air consumption, allowing stable operation with small air compressors. It performs well in remote working areas and mines without high-power air supply systems.
Application Scenarios
- Underground mine roadway development
- Blast hole drilling in stopes
- Bolt support hole drilling
- Secondary breaking
- Tunnel construction and stone works
