Tools used in mining

Safety in mining is a priority that determines the choice of tools and technologies used. Working at depth, in environments with an increased risk of explosion and harsh weather conditions, requires the use of equipment that meets stringent standards. Tools used in mines must not only be effective but, above all, safe—which is why they are non-sparking, corrosion-resistant devices, often powered by a generator or manually, designed specifically for use in explosion-hazard zones. Hydraulic and pneumatic tools play a key role here, combining high performance with reliability and durability.

Hydraulic tools in mining

Hydraulic tools are devices in which energy is transmitted via a working fluid (most commonly hydraulic oil or a water-oil emulsion). Made from high-quality carbon and alloy steels, they are characterized by an exceptional power-to-weight ratio and resistance to harsh environmental conditions. This makes them indispensable in mines, where both operating force and compact equipment size are critical.

The mining industry utilizes a wide range of hydraulic tools, which are used in both daily operational work and rescue operations. The most important of these are:

• Hydraulic wedge spreaders – enable lifting, precise equipment installation, widening of narrow openings, as well as rescue operations. Examples include the Enerpac WR-15, WR-5, and A-92 models, which feature a lifting capacity of up to 10 tons and can be operated by a single person.
• Hydraulic rope, cable, and bar cutters, as well as pipe cutters – allow for the quick and safe cutting of steel components, cables, or pipes, which is crucial during emergencies or rescue operations.
• Hydraulic-powered reciprocating saws and band saws – enable precise cutting of even very hard steel materials, used for dismantling structures, cutting out elements of tunnel linings or guides.
• Hydraulic drills – designed for drilling holes in coal, rock, and concrete, often used during anchor installation or preparatory work for controlled blasting. These devices are easy to operate, durable, and suitable for use in explosive atmospheres.

Examples of the advantages of hydraulic tools:

• Non-sparking – minimizes the risk of explosion in methane-rich areas.
• Corrosion resistance – ensures a long service life in humid and aggressive environments.
• High power with low weight – facilitates transport and operation in narrow workings.
• Capable of operating in Ex zones (explosion-hazard areas).

In the day-to-day reality of a mine, workers often rely on proven hydraulic tools, which, thanks to their design and reliability, allow for the quick and safe completion of even the most demanding tasks.

Sample list of hydraulic tools used in mining:

• Wedge spreaders and hydraulic cylinders
• Cutters for ropes, cables, rods, and pipes
• Circular and band saws
• Hydraulic drills
• Hand-operated and generator-powered hydraulic pumps
• Hydraulic and mechanical pullers
• Hydraulic presses

Pneumatic tools in mining

Pneumatic tools use compressed air to generate mechanical motion. They are particularly valued in mining due to their high efficiency in underground operations and their safety. The air tanks in these tools are made of shatterproof materials, and operators are protected by dual safety valves, which minimize the risk of accidents.

Among the pneumatic tools used in mining, we distinguish:

• Circular and band saws – designed for precision cutting of both metals and other construction materials.
• Pneumatic torque wrenches – used for loosening and tightening threaded connections, especially where torque control is required.
• Impact wrenches and hammers – enable fast and effective assembly and disassembly work, useful for maintaining machinery and road support structures.
• Rust removers and pneumatic drills – used for drilling holes in coal and rock, as well as for removing corrosion from steel components.
• Pneumatic pumps – used for transporting liquids and dewatering mine workings.

Key advantages of pneumatic tools:

• No risk of sparks – crucial in explosion-hazardous environments.
• Lightweight and portable – facilitates work in hard-to-reach areas.
• High performance – allows for quick completion of tasks even under the most challenging conditions.
• Resistance to moisture and dust – a key feature in underground mines.

Sample list of pneumatic tools used in mining:

• Circular saws and band saws
• Impact wrenches and hammers
• Torque multipliers
• Pneumatic drills
• Rust removers
• Pneumatic pumps
• Compressors and safety valves

Non-sparking and corrosion resistance – the key to safety

All tools used in mining must comply with standards for use in potentially explosive atmospheres (Ex, ATEX). Non-sparking means that even if the tool strikes or rubs against another metal, it will not produce a spark, eliminating the risk of igniting methane or coal dust. Additionally, these tools are designed from corrosion-resistant materials, ensuring their long service life and reliability even in the highly humid environment of a mine.

Examples of features of non-sparking tools:

• Made of aluminum bronze or brass
• Non-magnetic
• Durability and resistance to mechanical damage
• Certificates of approval for use in Ex zones

Summary

Modern mining cannot do without specialized hydraulic and pneumatic tools. Their safety, performance, and reliability are crucial for the efficient operation of mines and the protection of workers’ health and lives. When selecting tools for mining operations, it is important to consider their spark-free design, corrosion resistance, certifications for use in explosive atmospheres, and the manufacturer’s technical support. You’ll find a wide selection of proven tools in our hydraulic tools lineup, featuring products from renowned brands such as Enerpac and Chicago Pneumatic.

With the right selection of equipment, mining becomes not only more efficient but, above all, safer for people and the environment.
