| One of the most important problems of contemporary mining aerology is considered in the present paper - the ensuring of normal atmosphere, when working underground and using stationary and mobile diesel equipment there. Taking oil shale mines in Estonia as an example, it has been shown that a convective-diffusional removal of harmful components from the exhaust gases of diesel equipment in the operating zones of mines by means of general mine ventilation is impossible. It has also been indicated that, when trying to solve this problem, such methods seem to be effective that make it possible to reduce the concentrations of exhaust gases already at the initial stage of gas formation. The description of one of the most modern methods is given here, worked out by a Swedish firm LEMI AB. The results of the tests were carried out on bulldozers operating in mines and the LEMI-system was applied. |
