Optimal development of the quarry's working zone by the complex deposits exploitation

摘要

Projecting of the quarries for the complex deposits working and planning of their effective exploitation with maintenance of up-to-date demands of entrails rational development and environment preservation is very complicated multifactor problem. The least labour-intensive way of its optimal solving consists in determination in the first instance of the rational geometrical forms of the working zone at every stage of the quarry exploitation by one or another criterion. Depending on complication of the developing object minimum of the coefficient of stripping, mining mass, ratio: "profit"/"expenses" (coefficient of expenseness) can be used as the criterion of the variants estimation. The integral criterion - the coefficient of expenseness - allows to take into account the appropriateness of changing of geological data, the level of complex use of mineral raw materials, technological possibilities of its excavation and processing, conjuncture of the market, other economic and ecological demands.
