diggability for surface mining

Diggability, a measure of dragline effectiveness and Given the capital intensity of the dragline operation coupled with rising cost of explosives, the onus is on mine operators to make maximum use of explosives in blasting to assist dragline diggability At a surface coal mine in South Africa, large boulders necessitating secondary breakage and in some cases completely

Diggability For Surface Mining

Mining . Surface mining (also known as open-pit or open-cast mining ) and quarrying are used to extract stratified mineral resources that are close to the ground surface for example lignite coal metalliferous minerals industrial minerals and aggregates (Read and Stacey 2001 Smith and Collis 2001) A principal limiting factor is the stripping

Derivation of a diggability index for surface mine

1984-8-1  The Index is derived by summation of the 311 appropriately rated W, S, J and B values. Weathering was included to account for its effect on reducing discontinuity shear strength as well as intact rock strength. The highest rated parameter, J, refers to the mean of joint spacings in two orthogonal directions.
