Achieve Coal Mine Safety Regulations for Inert Gas Utilizing Nitrogen Generator Systems

The primary application for nitrogen gas use in the mining industry is extinguishing coal mine fires. However, updated regulations require miners to inert abandoned/worked-out areas of the mines if insufficient seals are installed (note: this is mandated by Final Standard 30 CFR Part 75 issued by the Mine Safety and Health Administration (MSHA) as of April, 2008).

The key initiative in extinguishing a coal mine fire is to reduce oxygen content of the combustive gases below the lower limit of explosion (LEL). Specialty foams are occasionally injected with nitrogen gas to help seal off air ingress to the fire and help cool the surface of the coal embers after the LEL has been achieved. Injection continuously is required for days, even months in some cases. Hauling or using liquid nitrogen to mining location is costly and yields safety concerns. A more reliable and cost effective method is to generate nitrogen on-site by utilizing a robust South-Tek Nitrogen Generation System.

The MSHA regulations for underground mine seals were developed to protect miners in active areas of the well from potential explosions in abandoned sections of the mines. Therefore seals must be designed to maintain a minimum of 120 psig within the abandoned or worked-out areas. If the seal requirement cannot be maintained and pressure drops (minimum seal pressure requirement per MSHA is 50 psig) additional nitrogen gas must be injected to satisfy pressure requirements. Per Federal Regulations, this process shall continue in order to maintain an atmosphere of 10% 02 or less.
