Application of Restoration and Remediation Technologies for Mine Geological Environments

摘要

Abstract

Mining activities have caused increasingly severe damage to geological environments, and the restoration and remediation of mine geological environments have become an important measure in ecological civilization construction. Based on literature research, field investigation, and case analysis, this paper reviews mainstream remediation technologies for mine ecological restoration and their application effects. The main problems in mine geological environments include surface subsidence, slope instability, water and soil pollution, and vegetation destruction. Existing remediation measures can be mainly divided into three categories: engineering remediation, biological remediation, and ecological reconstruction. Engineering remediation rapidly prevents and controls geological disasters through slope reinforcement, subsidence backfilling, and drainage facility installation. Biological remediation relies on vegetation reconstruction, soil improvement, and microbial remediation to achieve natural ecological recovery. Ecological reconstruction reshapes the regional ecological pattern through landscape planning, functional zoning, and ecological corridor construction. The combined application of engineering and biological remediation produces the best comprehensive benefits, with both economic efficiency and long-term effectiveness. Remediation schemes should be formulated according to local conditions by considering mine type, geological and climatic conditions, and socioeconomic factors. This study provides theoretical reference and practical support for mine ecological restoration, green mine construction, and ecological environmental protection.
