Аннотация: В статье рассмотрены особенности нормирования показателей извлечения при подземной добыче кимберлитовых руд трубки «Мир» слоевой системой разработки с полной закладкой выработанного пространства и комбинированной отбойкой руды (комбайновая и буровзрывная) при нисходящим шахматном порядке отработки очистных лент. To ensure the perfoПоказать полностьюrmance of the proposed mine, the mine has been accepted layers of the system development with a descending order of mining layers mechanized ore breaking and complete stowing. Reserves of layers of individual ribbons are removed. Refinement treatment tapes of adjacent layers is performed in a staggered offset horizontally by half the width of a tape. Who goes to the mine layers system with increased height layers - up to a height of two layers. Application of the method of the recess reserves ribbons increasing altitude using a harvester Vege and drilling and blasting destruction of the ore allows maximum use of the natural carrying capacity of the ore and the filling mass, increase the geometric dimensions formed in the recess of the cleaning space, and hence improve the performance of sewage treatment works, as well as reduce losses the extraction of ore. To facilitate the conduct of settlements created and implemented a specialized computer program to calculate the ratios of losses and dilution of ore in mining ore by underground methods. Its main features - the calculation of absolute and relative values of normative losses and dilution of ore reserves to pay off the balance within the stope, tape layer, the excavation unit; individual components of the system development. It is designed to calculate the normative values of losses and dilution, and can be used at the planning stage mining operations (preparation of schedules of development of mining operations), as well as at the stage of local projects in the testing of certain balance sheet reserves. Implementation of the program allows you to eliminate manual invoice and more accurately calculate the amount of losses and dilution of ore; significantly reduce the volume of work involved in the planning and standardization of parameters extracted from the subsoil; create electronic records and archives, as well as display the final documents to the printer.
