For comparison of environmental performance of rock mass hoists, methods of calculating the volume of harmful emissions into the environment and comparative assessment of their environmental characteristics and economic efficiency are developed. According to the results of calculations recommendations are given and estimated data on the operation of the most promising designs of hoists in deep quarries are given.
The results of calculations of efficiency of application of the main methods of normalization of the atmosphere of the open pit are given. As an example, the conditions of open pit Udachny of AK Alrosa and the basic models of dump trucks with carrying capacity of 100-150 tons of domestic and foreign production are considered. The model and the developed medicine allow to substantiate the choice of optimal transport complex taking into account the dynamics of mining works, the environmental factor and various models of loading and transporting equipment.
Due to the unsatisfactory environmental situation in the areas of mining complexes, special attention should be paid to environmental safety when selecting equipment. The results of the calculation of the transportation complex on the example of Udachny open pit of ALROSA's diamond mining company are presented. A quantitative assessment of damage associated with equipment downtime is made. A total of five different options have been considered, four of which use different ways to reduce the harmful effects from the operation of diesel dump trucks. The most economical variant, which allows to reduce not only harmful impact, but also the cost of transportation of rock mass, is determined.
