Abstract:

The best economic models of groove depth is established based on groove inclined turning’s feature and the criterion of groove depth depend on the principle that the production stripping ratio is not greater than the economic stripping ratio.It is identified that the total benefit is a cubic function of the groove depth and the computing formula of the best groove depth is derived. Last the analysis of a mine’s actual situation demonstrates the usefulness of the model .

Key words: groove inclined turning, groove depth, stripping ratio, single circuit transport
