The article considers one of the most pressing problems of modern mining science - the problem of formation and development of technogenic deposits. It is known that modern technogenic deposits were formed by the method of bulk dumping, taking into account only two requirements: the minimum cost of dumping work and ensuring the stability of the slopes of the dumps. It is proved that the solution of the problem of complex use of technogenic deposits is connected not only with the possibility of increasing their consumption today, but also with the necessity of creating perspective sources of raw materials. In this connection the question of formation of technogenic deposits acquires paramount importance. The passport of the stockpile of rocks - wastes of the open pit of Kostomuksha Mining and Processing Plant is presented. The fourth main technological process of open-cast mining is proposed to be termed not as dumping, but as stockpiling.
