Vesnin A. The reduction of the harmful influence of the fulfilled gases of the motor transportation streams on the structure of an atmosphere of the quarries.

The purpose of work is reduction of influence of emissions of a motor transportation complex career on the structure over an atmosphere, due to optimization of the modes of its operation by the making use of the means of reduction of the concentration of the harmful components in the fulfilled gases. The coefficients of unpermanent work of the motor transportation equipment of the quarries are determined on the basis of theoretical researches and experimental measurements and the method of calculation of consumption of fuel is advanced by a motor transportation stream. Laws of the distribution and the change of the concentration of the harmful impurities of fulfilled gases in a gas loop of vehicles are established, depending on type of the automobile, structure of an atmosphere and the change of intensity of a stream in the conditions of the quarries. The installation for clearing fulfilled gases by transportation of the loose materials is created on the basis of laboratory researches and tested by theauxiliary motor transport, and also practical recommendations for the reduction of the harmful gas evolutions by a motor transportation complex quarry taking place in direct operation are developed, by optimization of parameters and the modes of movement of a stream with the application of the devices, reductions of concentration of the fulfilled gases. The settlement annual economic benefit will make 411,08 thousand grn., due to increase of labour productivity of drivers and the attendants, as a result of improvement of sanitary-and-hygienic conditions for conditions of the PivnGZK's May Day quarry.
