Derivation of a diggability index for surface mine ...

1984-8-1 · The limitation of the available ground pre- paration and excavating techniques employed in the wide range of surface mining rock masses can only be defined by concerted re- search and field validation. This paper is con- cerned with the means of deriving an excavat- ing or diggability index for use in mine de- sign.

Derivation of a diggability index for surface mine ...

The work was conducted in operating British surface coal mines and presents a technique for diggability assessment in that mining and geotechnical environment. A diggability index is proposed which consideres both ground conditions and excavating equipment capabilities. This is supported by reference to back-analysis of several mine excavating ...

2013-5-9 · In surface mining and civil engineering projects, terms such as diggability, rippability, excavatability and boreability are widely used to assess rock mass excavation methods and required equipment. The rippability index was defined for assessing overburden loosening by rippers (Caterpillar Inc. 1988).
