The most common purification methods in the coal industry are settling ponds and filtering treatment constructions. But in some cases, the use of traditional methods and schemes of water purification is complicated by the conditions of water discharge or does not provide the required water quality. For example, sharp seasonal fluctuations in the level of discharge and water pollution, a large number of spillways distant from each other and a change in their location during the development and moving of mining operations often make it difficult to use expensive and difficult to operate industrial wastewater treatment plants. Often, mining enterprises have a shortage of land areas to place such plants. In this regard, studies have been conducted aimed at identifying the possibility of water purification from suspended solids by filtering in arrays of coarse rock and semi-rock. Such arrays included, first of all, overburden dumps, various technological dams and embankments, as well as specially constructed filter arrays from mining waste. This article presents the results of studies to determine the location of the filter massif in the open pit “Kamyshansky”.

Contemporary mining industry is a complex system that is constantly expanding both in terms of explored sources of mineral raw materials and in terms of developing new approaches to mining and processing of minerals. Such a buildup in the scope of tasks set for the industry, as well as the technical progress, lead to various issues related to the quality, quantity and rational use of mineral raw materials. Rationalization, in its turn, should be carried out in a phased manner through the use of comprehensive measures, one of which is reclamation of man-made wastes, represented by waste rocks, tailings, slags, dust, etc. In addition, this approach simultaneously resolves several other important challenges the industry is facing, e.g. increasing the environmental safety of mining regions and increasing the economic feasibility of production by extracting additional components from waste materials. The scope of application of such a solution to the challenge of rationalizing production is immense and can be implemented at many deposits located in the territory of the CIS due to the presence of huge volumes of waste generated by mining raw materials. These wastes were accumulated because of the absence of full-fledged technologies to extract useful components from the rock mass in the past as well as other requirements to ore conditioning than those acting today. For example, in the Republic of Bashkortostan, the overburden dumps and off-balance ores that have been created by mining enterprises amount to more than 1 billion tons, hydraulic-mine dumps of processing plants reach 50 million tons, manmade waters exceed 9 million m3 annually. At the same time, the amount of useful components contained in these man-made deposits can be up to 1.5 million tons for copper, 2 million tons for zinc, about 100 tons of gold as well as significant amounts of other associated components, including various non-metallic formations.
