Bit geometry effects on failure characteristics of rock

Mining Engineering, 2000, Vol. 52, No. 6, pp. 0-6
Achanti , V.B.; Khair, A.W.


ABSTRACT:
Efficient rock breakage is a result of the optimum use of available resources in a continuous mining system. Research has demonstrated that specific energy and specific respirable dust must be kept at a minimum to produce the optimum parameters of the rock-breakage process. The specific airborne dust or specific respirable dust is defined as the amount of respirable dust generated during a unit mass of rock/coal removal. The specific energy is defined as the amount of work done to remove a unit mass of rock/coal during the cutting process. This study investigated the influence of four bit geometry parameters on specific respirable dust and specific energy during rock cutting.
