----- Benefits of an Enclosed Gob Well Flare Design for Underground Coal Mines Addendum to: Conceptual Design for a Coal Mine Gob Well Flare (EPA 430-R-99-012; August 1999) I. INTRODUCTION This paper considers the benefits offered by an enclosed flare (also known as a thermal oxidizer flare) for use at underground coal mine gob wells.withdraw gob gas, a one way check valve, a flame arrestor and a flare stack. EXPERIMENTAL METHOD Approach The general concept of the gas flow characterization experiments is to release a defmed volume of the tracer gas into the ventilation airflow or longwall gob and then monitor all potential exit points for the gas (Thimons, eta/., 1974;

Aug 24, 2017 Mining Contract: Design of an Optically Accessible Scaled-Version of a Longwall Coal Mine for Investigating Explosion Hazards. This scale model will allow researchers to better study the flow of methane within a longwall mine environment and explore possible ventilation strategies to mitigate the risks of such an explosion.The Mine Act requires every underground coal mine operator to adopt a ventilation plan “suitable to the conditions and the mining system of the coal mine and approved by the Secretary [of Labor].” 30 U.S.C. 863(o). This matter concerns the ventilation plan for Knight Hawk Coal’s Prairie Eagle Underground Mine …
