PROCEDURES FOR STAGE PROCESSING OF IRON-ORE WASTES IN INDUSTRIAL MINING AREAS

Authors substantiate development of management procedures for the step-by-step processing of iron ore wastes of mining regions that provide a full cycle of rational nature management through the introduction of waste-free and low-waste technologies, followed by reclamation and creation of recreation areas for people. Procedure for operating enterprises has been developed, that consists of structure and sequence of operation stages, sump recovery scheme, technological preparation of equipment, calendar plan. Stages are carried out in parallel and consist of waste recycling, reclamation, search, analysis and selection of tenders for recreational areas development. Waste processing and land reclamation are carried out during operation of mining enterprise. Commissioning of the territories intended for recreation of mining areas population is carried out after enterprise liquidation. Management of step-by-step processing of iron ore wastes for closed enterprises consists of the following stages: search for finance support for technogenic resources utilization and reclamation of disturbed land through the sale of available fixed assets (buildings, structures and equipment) and call for investments, including the state ones. In case of insufficient financing, part of iron ore waste is used as construction or packing material for reclamation. Management of the step-by-step processing of iron ore wastes for the projects under implementation includes non-continuous monitoring of man-made resources formation and land disturbance. When wastes are generated, an analysis of existing technologies aimed at their utilization and reclamation of disturbed lands is carried out. Non-continuous monitoring helps to prevent potential environmental damage. During operation of enterprise, step-by-step development of recreation zones is carried out with its subsequent commissioning after the enterprise liquidation. Based on the proposed management of step-by-step processing of iron ore waste, scenarios for waste-free and low-waste technologies introduction in the Tashtagol District of the Kemerovo Region have been developed. Their simulation was carried out in SciLab. The problem of processing scenarios ranking has been stated and solved.
