Technogenic Surface Formations within the Limits of Mining-Industrial System of the Dalnegorsky District of the Primorsky Krai as the Reclamation Site

Abstract

Abstract The article presents the results of long-term researches of the problem of reclamation of technogenic surface formations (TSF), of tailings surface of Dalpolpolymetal mining enterprise containing toxic heavy metal compounds. The purpose of the research was to create a method of tailings surface reclamation, providing for increasing the reliability of its closing, shortening of reclamation period, reducing the risk of technogenic catastrophes and ensuring the ecological and social safety. Based on the purpose of the study, the following tasks were formulated: 1. Analyze and summarize the literary data on the problem of the research of technogenic surface formations (TSF) within the limits of impact of technogenic system as the reclamation site; 2. Estimate waste as a potential source of ecosphere technogenic pollution; 3. Give proposals on ecological and social safety of tailings containing toxic heavy metal compounds. On the basis of soil-ecological conditions of the studied area the characteristic of technogenic surface formations is given. The proposals for environmental and social safety of tailings containing toxic heavy metal compounds have been developed.
