MSHA Approved Hoses:
Protection in Mining Conditions - Key Features and Standards.
In Mining, one of the toughest and most demanding industrial sectors, Hydraulic and Industrial Hoses play a significant role. Their proper selection ensures the safe and efficient operation of machinery and transport systems in extreme mine conditions. In this article, we will discuss why properties such as Flame Retardant, Antistatic and compliance with stringent technical standards are crucial for safe and efficient operation of miners.
Properties of Mining Hoses
- Flame Retardant
In the mining work environment, where fire and explosion hazards from methane and coal dust are ever-present, Flame Retardant of the materials used for Hoses is absolutely crucial. Specialized Hoses Stomil - are designed to minimize the risk of ignition due to high temperatures, sparks or contact with flames. In emergency situations involving fires, properly selected flame-retardant HOSES can prevent the spread of fire, thereby protecting equipment and personnel.
- Antistatic
In the course of mining operations, electrostatic discharges can occur, which is why anti-electrostatic properties are so important. The rubber compound from which they are manufactured Hoses 1SN (TA) EN 853 MSHA Stomil, intended for Mining, contains in its composition special additives that prevent the formation of static charge on their surface. Electrostatic discharge in the presence of coal dust can lead to explosions, hence the stringent requirements that must be met by HOSES used in machinery and equipment operating in underground workings of mining plants.

Technical Standards
- EN853, ISO 6805, PN-G-32010
All Hoses used in Mining must meet certain technical standards that regulate issues such as:
- EN853: Applies to Hydraulic Hoses, specifying requirements for Working Pressure, Abrasion Resistance and Compatibility with Hydraulic Fluids.
- ISO 6805: An international standard covering high-pressure hoses used in the mining industry, regulating aspects of durability, compressive strength and safety of use.
- PN-G-32010: Polish standard defining the specifications of Mining Hoses, with emphasis on their mechanical strength, chemical resistance and anti-electrostatic requirements.
Hoses design
Specialized Hoses 1SN (TA) EN 853 MSHA Stomil used in Mining, meet the above standards. Their construction consists of three layers. An inner layer - made of synthetic rubber - resistant to oil and water. Subsequently, a reinforcing layer - with one or more braids of high-strength steel wire, and an outer layer, which is also made of synthetic rubber. The outer layer is additionally flame-retardant and anti-electrostatic, resistant to abrasion, oil, weather and ozone.
Such a multi-layer solution increases resistance to Working Pressure and protects against mechanical damage.
Standards - MSHA
Hoses that meet the requirements of the Mine Safety and Health Administration (MSHA), the U.S. Mine Safety and Health Administration, are rigorously tested for Flame Retardant and anti-static properties. Thus guaranteeing safety for use in Mining.
Applications
Hoses 1SN (TA) EN 853 MSHA used in Mining are used in various areas, including:
- Extraction of „dust” from drills - fine particles when drilling holes for anchors
- In Glue Transfer Machines - Which closes the holes with an anchor. Resistant to chemicals and provides adequate pressure for proper operation of equipment
In summary, choosing the right Hoses in Mining is crucial for safe operation and operational efficiency. Hoses that comply with EN853, ISO 6805, PN-G-32010 and MSHA-approved standards not only ensure durability, minimizing the risk of machine downtime, but also meet safety requirements.
