mines were small, using shrinkage stoping and small mine can. The capacity of material handling was small, limiting the size largest piece and the feed rate. Improved material handling resulted in more and more large open pit mines with large shovels and a tremendous increase in the size of off road or mine haul trucks rail can. Primary
