Abstract

The paper analyses problems associated with the use of mining machinery equipped with diesel engine releases of exhaust gases that have a harmful impact on human health and the environment. The mining industry uses a wide range of equipment powered by diesel engines: dump trucks, backhoe loaders, drill jumbos and other mining machinery. Engine exhaust gases contain toxic elements that have a significant impact on human health and the environment. Air pollution from gases leads to standbys of mine sites, while a reduced visibility on a route results in a partial or total equipment shutdown. At present, environmental requirements to vehicle engines are a top concern. The problem of air pollution with harmful substances contained in diesel engine exhausts is becoming a global challenge. Solutions of these issues require joint efforts from many countries. International conventions and adoption of relevant standards serve as a means of rapprochement in this sphere. Most operations in Europe, Asia and America are guided by similar standards as to the content of harmful substances in exhaust gases, the European Union being an influencer in this regard by frequently introducing updates and stringent regulations. Other countries are following this trend and revising their emission standards too. European states had paid attention to this issue earlier than other countries. Today, environmental requirements to vehicle engines are a top priority. Research in this field is focused on such issues as increasing productivity of mining machinery engines, reducing labour costs of maintenance and repairs, enhancing fuel efficiency and significantly improving environmental performance.
