Diggability, a measure of dragline effectiveness and

1996-12-1  Mining systems now often include: truck/shovel prestripping ahead of dragline operations; dragline high walls of 50 meters; total pit depths in excess of 80 meters; mining of multiple coal seams, thin seams and thin partings; more focus on (and measurement of) excavation equipment productivity; and/or conformance to strict environmental limitations.

Can you dig it? UBC PhD candidate develops

2016-8-31  It even allows the mine maintenance engineers to understand what sort of digging causes the most damage to the machine. A focus on diggability is especially relevant these days as the mining industry is under pressure to control costs. Diggability is a measure that helps us decrease mining costs at steelmaking coal mines as well as metal mines.

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 case
