Kirity Kumar, Quaker Houghton, USA, explains the need for fire resistant hydraulic fluids and their importance within the coal mining industry.
The unyielding threat of fire in coal mines
The coal mining industry has long grappled with the danger of fire hazards. Flammable gases and coal dust are inherent features of these underground environments, creating a volatile cocktail that demands utmost caution. While effective in facilitating machinery operation, traditional hydraulic fluids can inadvertently escalate the fire risk due to their flammable nature. The dangers of catastrophic fires and explosions are ever-present, threatening miners’ lives, the integrity of equipment, and the stability of mine structures.
Heavy-duty machines like continuous miners are used to cut through coal seams. Shuttle cars transport the precious cargo amidst confined spaces, and roof bolters secure stability, warding off potential collapses. Load haul dump (LHD) loaders deftly scoop and transfer coal to conveyors within the pitch-black depths. Yet, the criticality of equipment is the harshness of the surroundings – extreme pressures, high temperatures, moist and dusty air, and the constant risk of fire hazards.
In response, the demand for fire resistant hydraulic fluid becomes vital, as these fluids optimise machinery performance and offer a crucial layer of protection against ignition risks in an environment where a single spark could spell catastrophe. These specialised fluids boast a remarkable quality: high ignition temperatures. Unlike their conventional counterparts, fire resistant fluids are engineered to withstand ignition under the extreme conditions prevalent in coal mines. This inherent resistance reduces the risk of hydraulic fluid-related fires and explosions. Safety, though paramount, is only one facet of this transformative shift. Coal mines, often nestled in ecologically sensitive regions, can be environmental hotspots due to the risk of spills and leaks from hydraulic systems. While fire resistant hydraulic fluids cannot entirely prevent equipment leakage, their biodegradable nature and compliance ensure they do not threaten aquatic life.
