calculation of tonnes per machine shift in mining CALCULATION OF MACHINE RATES THE FORMULA FOR CALCULATING UP HOLE VELOCITY The modern mining equipment required to remain competitive in today s coal
In a large mine where the working faces are far from the main loading point an intermediate transport arrangement operates and it is known as secondary haulage The main methods of transport are as follows A Rope Haulages 1 Direct rope haulage a Single drum direct rope haulage b Double drum direct rope haulage 2 Main & tail rope haulage
The invention of LHDs can be said to be a milestone in mining Ever since its inception the load haul dumper become a dominant machine in mechanized mines and plays an important role in overall mine production [1] LHDs are very reliable and powerful machines capable of working in the most hostile of conditions

respectively The mine uses four different mining methods sublevel open stoping in zones A and B; drift and fill mining in zone C; narrow vein mining in zone C; Alimak mining in zones A and B This paper focuses on the sublevel open stoping mining used in zone A In this method top and bottom accesses are mined to reach the sublevel open stope
Average tonnes per team per shift within Sasol s mining units is 1300t compared with over 2200t and 3 500 t at peak for the face miner/haulage teams Keeping a handle on equipment cost and extending equipment life between overhauls are major areas of focus for the mine Machine availability is similarly a major focus for the mine
At Cripple Creek machine men cost $ a shift or 24c a ton; air $2 a shift or 13c a ton; repairs and lubrication 25c a shift or 2c a ton; drill steel and sharpening 50c a shift or 3½c a ton Total for drilling $ a shift or 42½c a ton
