Analysis of the mobile complex structure for organogenic materials mining by in-pit method

As a result of the studies performed, the advantages of the system of in-pit processing and transportation of processed peat are shown. These systems allow for primary processing, separation of production waste and reduce the volume of in-pit transportation and transportation costs. A number of intensive principles for the formation of the structure of a set of equipment for the extraction of organogenic materials by the in-pit method are considered. Completion of equipment should be based on the analysis of limiting conditions and the establishment of areas of permissible modes of machines operation. The main types of mobile mining and loading equipment, equipment for crushing and mechanical dewatering of peat, transport units and a module for compaction of peat are recommended. The relationship when choosing a set of equipment is based on an operational indicator — productivity. In the course of performing successive technological operations from the extraction of peat to its compaction and drying, the density is transformed from 860 to 430 kg / m3 with a decrease in moisture content from 9.0 to 1.86 kg / kg, and by-products are extracted. This, in turn, determines the size-mass and energy parameters of the technological equipment employed in each technological operation. The final product is a compact — a dried bulk semi-finished product from peat for the further production of a number of products for agro-industrial and environmental purposes. The results of the research performed can be used for the technical re-equipment of technological equipment fleet and the selection of a rational set of equipment at the stage of developing projects for the development of territories with soft soils.
