Total 200 machines and the working shift is 10 hours per day. Total factory capacity per day is 2000 hours (200 machines * 10 hours). If the factory is producing only one style (Shirt) of SAM 25 minutes and used all 200 machines daily production capacity at 50% = (2000*60/25)*50% Pieces = (2000*60*50) / (25*100) Pieces = (/2500) Pieces
Calculate availability of machinery as one component of overall machinery productivity performance. Establish the total available hours for the machine. This can be represented by the total number of hours the machinery can be used in a day or shift normally 8, 10 or 12 hours.
Powder Factor = Tons of rock (or cubic yards) per pounds of explosive. Normal range = 4 to 7 Shallow holes = 1 to 2 External loads = .3 Tons of Rock = Powder Factor lbs of Explosives The higher the powder factor, the lighter the load. Lower powder factor means more explosives. Example: tons = PF of BURDENSPACING CALCULATION
