The study in the area of ecology is an essential part of geology prospecting. It must be carried out at the earliest stages of exploration of deposits and is to take into account the dynamics of change of the ecological situations at all stages of exploitation. In terms of the database set up to analyze the operation of the Udachninsky dressing mill there has been made an all-around ecology monitoring and as a result of long-term exploitation of the Udachninsky kimberlite pipe the dynamics of technogenic change of landscape is shown hereinafter.
