Abstract
The article presents fundamental differences in the position of solving the problem of neutralization of waste gases in underground and surface mining operations. It is shown that for underground conditions this problem is practically solved by application of effective neutralizers of waste gases. Constructive improvement of neutralizers is carried out mainly in the direction of cost reduction due to the use of special catalysts instead of platinum. Neutralizers are not used in load-bearing mining operations because of large volumes of waste gases and their low efficiency at temperatures below 300. Other ways of normalizing the atmosphere are presented. The main ones are the use of engines that do not pollute the atmosphere with harmful exhaust gases; reduction of fuel demand by optimizing operating modes; use of special fuel additives that reduce soot output by about 2 times.
