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 ...
