摘要:

根据生产剥采比不大于经济合理剥采比原则确定的留沟深度判定准则及直角留沟缓帮转向的特点,建立了以缓帮留沟高度为基本变量的最佳经济效益模型, 得出了留沟总效益是关于留沟深度的三次函数, 并推导出了最佳留沟深度计算公式。通过对我国黑岱沟露天煤矿实例的分析,论证了该模型的实用性。

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
