Abstract:The action mechanism of the load of a dump on a flat surface soil substrate was discussed, according to the thickness of surface soil substrate and the conditions under which it contacts with waste rocks. An equation for critical surface soil thickness, hm and equation for determining the limiting height of a waste dump were derived. It was pointed out that the existing equation is a special example among them. Finally, two successful examples were presented in detail.
Key words: rock disposal dumps; limit height; critical thickness
