Underground mining slurry transportation viability

摘要：Underground mining requires lot of water pumping to surface which increases cost.Because of safety,support,ventilation and environment costs underground mines are closing down gradually all over the world.This innovative paper is based on method studies by computer programming with realistic data.With development of electronic control systems,coal water slurry mix can be remote controlled for transport to surface Separator-bunker.Main consumers need powdered coal/mineral like thermal power stations,for feeding to Fuel Burners of boilers,generating power or in steel plants for feeding into coke ovens to make hard coke for charging into Blast Furnaces for making pig iron.Feed for coal washeries also require crushed coal and output of washed coal as slurry can be sent to coke ovens of steel plants directly.Production from mine faces should be taken through lump-breaker and conveyed to a mixing chamber,near panel sump,from where adequate capacity slurry pump will propel up to pit-top.The projected financial benefit can be several millions of Rupees per year,as compared to road,rail conveyor or winders is shown,by run of a computer program in Java,with realistic cost figures from mines.
