Property and Control Measures of Soil Pollution in Mining Area

摘要

Soil pollution problem in mining area has already caused the extensive concern in the world, where the protection and remediation of soil pollution is even more important than atmosphere pollution and water pollution. The mineral resources in China are various, and therefore the types of soil pollution are numerous. This paper analyzed the soil pollution characteristics of several kinds of mining areas. The soil pollution of coal mining area is mainly from coal gangue, fly ash and mining sewage. Therefore, prevention and cure to these pollutions mostly depends on isolate and covering etc. The soil pollution in metal mine is mainly surrounded by the tailing and slay, where companies with serious heavy metal polluted. As a result, the prevention and remediation method includes fixing, isolation and remove and so on. The soil pollution of oil filed is mainly caused by the running, emitting, dripping and leaking of the crude oil in the process of producing, storing, transporting and assigning, which primarily shows as organic matter pollution, and the measure of prevention and remediation lies on biological, physics and chemical law.
