WHAT IS O.M.S??
O.M.S means output tones per man per shift.It is a method of Expressing the productivity of mines of loader.**Condition of longwall method:-Seam thickness-0.6to2.4m.Moderate depth. Inclination-flat to20*Depth-More than500m.InL/W working with coal plough,seam thik ness is 0.6m to 2m. Ploughability of coal seam determine as Per ISI( impact strength in Dex) . Where coal is hard in this case water in fusion of the coal face proceed the ploughing operation.Whater infusion is a process of drilling 1.2m to 1.5m.deep holes spaced 3to 6m interval along the direction 45*to it, pressure forseing water 6to10kg/cm2 through them.#Machinanised used in mechansid L/W face" DEARD,DEARD,SHEARER,AFC,POWERED Support,gate belt conveyor,stage loader,In seam miner,Road header..
