Coal excavation is a unsportsmanlike , serious business . Even with New safety equipment protect workers from inglorious lung , plenty of other dangers look them underground . Like , say , mixing easy erupt coal dust with hot machine surfaces . That ’s why GE has invented a mine - car engine that keeps its cool to prevent set off a raging pit .
ember rubble , an intractable byproduct of the ember - minelaying operation , is very combustible with an ignition level of just 325 degrees F. If that dust derive in touch with an heart-to-heart flaming — or even a hot car engine — the entire area can can go up in flames in an New York minute . Hence , GE ’s Industrea Mk7.0 TIER 3 Mine Cruiser , an open - top subterrenean S.U.V. that sit 12 - 14 mineworker .
The Mk7.0 sport a specially designed 4.3 - cubic decimeter , 4 - cylinder diesel engine engine and exhaust system system that actively prevents actuate through the usage of arrestors and foreclose temperature spike above 300 degrees Fahrenheit , what Union OSHA rules requirement .
What ’s more , the fomite ’s exhaust flow lapse through both a water jacket ( wrap around the manifolds ) and a secondary water bath that removes particulate matter and further cools the evaporation ( like an automotive bong ) . By the time the gasolene cash in one’s chips the vehicle , it ’s “ below 77 degrees Celsius ( 170 Fahrenheit ) , ” Sean Lynch , manufacturing supervisor at Industrea , explained in a press statement .
The vehicle will even mechanically shut down if it find life-threatening engrossment of methane petrol , like a twenty-first century stoolie . [ GE Reports ]
