Abstract.Significant environmental impacts inflicted not only directly in the process of coal mining but for years after its completion. Waste dumps, which occupy large areas of fertile lands are the source of environmental contamination. Most of the coal industry waste contains significant amounts of heavy metals and therefore is especially dangerous to living organisms. So there is a need to study the mechanisms and regularities of heavy metals migration from waste dumps.

Ecological impacts analysis of long-term placement of dumps for the environmental objects is made. The research of environmental state of dumps placing areas of liquidated mines is conducted. The scheme of rocks and soil sampling to establish migration characteristics of heavy metals from waste dumps is proposed. Content of mobile forms of heavy metals of the first and the second danger class in the samples is defined. Solving the problem of waste management of liquidated coal mines requires the methodology development for assessing levels of environmental hazards.

Key words: mines liquidation, waste dumps, ecological safety, heavy metals.
