Methods to improve the waste rock dumping efficiency and reclamation under the north condition

Abstract

The mining industry adversely affects the environment. The ecosystems of the northern regions, where due to harsh climatic conditions, are particularly sensitive to this negative impact and has a low ability of local natural complexes to overgrowth. However, the current reality is that the principles of environmental protection are sacrificed to the stable economic development of the region. In such circumstances, the social responsibility of business and the promotion of rational subsoil use methods become a thing of a great importance. In accordance with the Russian Federation legislation in the field of mineral recourses use, the subsoil user undertakes in time, adjusted by the project of the mineral deposit development, to carry out the reclamation not only of the open pit itself, but also all other territories, disrupted as a result of the company’s business. Open pit mining, in the main, is associated with the need to store a large volume of waste rocks in dumps. In modern open pits, more than a third of a land allotment is occupied by waste dumps, and the cost of their reclamation has a dominant influence on the budget of restoration work in general. This study is devoted to the peculiarities of waste dumps reclamation in the North, methods of its efficiency increasing and ways of rational dumps formation, taking into account the requirements of subsequent reclamation.
