The innovative technology of peat extraction promoting power and resource-saving is offered. Completeness and complexity of peat field useful components extraction are provided on the basis of the nature protection principles of rational environmental management. Strip mining is the mining of a relatively flat field. Preparing the area after its drainage involves a basic series of technological procedures: collecting of wood wastes and removing to the storage, deep milling of the top layer; small wood residues collecting and removing to the area; field surface leveling and profiling (7 peat machines). Preparing the area after its drainage with the excavation of the top layer involves another series of technological procedures: collecting of wood wastes and removing to the storage, deep milling of the top layer; collecting and removing to the storage material for the top layer; field surface leveling and profiling (5 peat machines). In the proposed flowsheet with deep peat milling the top layer is loosened and mixed (roots of trees, shrubs, parts of grass and moss vegetation, woodchips, peat of small decomposition degree). Then the whole layer is removed from the peat field for special treatment. For peat production, there is an undisturbed peat deposit surface, clear of a waste layer.

This work describes the preparation and characterization of tubular peat granules for potential use in the field drying process, consisting of a mixed peat structure. Hollow peat tubes having internal diameter 30 mm and overall diameter 60 mm were produced by extrusion and used as a unit for the field drying process. The primary goal of this report is the development of the combination of fiber peat (top layer of deposit) with plastic peat (bottom layer of deposit) without additives and binders for producing a more stable and cohesive granule. The content of the mix was 1:5 by volume. When the moisture content was increased to 80% by mass (weight), moist pellets were formed. A simple test was performed on the peat samples to confirm the mixing efficiency. The advantage of such tubular geometry is that it provides 1.6 times higher surface area/volume for field drying process intensification. Promising results were achieved, in particular, when tubes with a bigger diameter were used. The method is inexpensive and simple to scale; however, further research is needed in view of a final optimization.

The purpose of this paper is to analyse the application of fully mobile plants for raw peat crushing, mixing and separating of wood inclusions and for mechanical dewatering in peat open-pit mines to increase the efficiency of mining. In-Pit Crushing and Conveying Systems (IPCC) which characterized by their economic efficiency, reduction of labour costs, haulage costs, fuel consumption and pollution (dust and noise) compared to conventional shovel-truck systems are well known. Full mobile In-Pit Crushing-Conveying and Dewatering System includes an excavator, two mobile plants: crushing and dewatering plants. The considered technology of primary processing of excavated raw peat has the following advantages: reducing trucks fleet; reducing transportation costs; an opportunity of continuous processing of peat; reducing the energy consumption of the crushers; eliminating the need to build water treatment plants in factories due to returning squeezed water back to the pit.

The article presents the fractal approach to the study of the five peat structure samples. Digital images from natural porous raw peat, intended for fractal studies of the porosity, are proposed. Peat active porosity is used in this study. In this study, the peat active porosity, fractal dimension (D), and their relationship with different peat samples were investigated in an experiment. The results of this study demonstrate that a fractal dimension analysis of peat compositions texture is a useful method for the quantitative description of the active porosity. The received results should be considered in the theoretical and pilot studies connected with physicomechanical processes occurring on the porous surfaces of peat raw materials during its mechanical processing.
