DESIGN METHOD OF RADIATION SITUATION DURING EXPLOITATION OF URANIUM DEPOSITS BY SYSTEMS WITH BLOCK CAVING (BY EXAMPLE OF MINES OF EAST ORE MINING-AND-PROCESSING ENTERPRISE)

By Leonid Ivanovich Kovalevsky

Abstract

There the analytical, full-scale and laboratory studies under the mine conditions have been executed. The coefficient of air demand of mine has been ascertained; it allows to design timely the ventilation system according to the radiation factor. The mathematical dependence for the radon emission into the underground workings, the empirical dependences of values of coefficient of ventilation efficiency of operating district on its characteristics have been ascertained. The method to predict the radon emission, to predict the air demand of mine has been developed; the method of experimental determination of values of radon emission indicators has been created; the effective ventilation schemes of breakage works with the application of collector, which allow to decrease the air demand of mine 1,5 - 3 times, to reduce the effective radiation coefficient of radon 3 - 6 times on the average for the work places. The study results have been included as the component of Temporary Manual to Design Ventilation of Mines of IndustryAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
