The main reason for the stoppage of mining operations was also identified in these areas; systematized deposits of magmatic and metamorphic origin in the Dnieper region, establishing water inflows into the produced space of the pits based on the area of the pit field, the exposure area of the sides of the pit, and the depth of mining operations; determined the dependence of the change in the safe distance for the placement of mining equipment during mining operations under the conditions of shear processes and the action of hydrostatic pressure; proposed technological schemes for the use of modern mining equipment in processing rock raw materials, featuring various productivity parameters ranging from 200 t/h to 350 t/h. These schemes encompass the full cycle of processing, resulting in size classes from 0-5 mm to 20-40 mm. The technological schemes presented for the technical support of complexes in the processing of mineral raw materials provide mining engineers and managers of mining companies with a broad assessment tool. This enables them to pre-assess the feasibility of re-equipping crushing and sorting plants, including the establishment of their operational efficiency. The results obtained from these assessments can be instrumental in the development of working projects for non-ore mineral raw material deposits or in the design and re-equipment of crushing and sorting plants.  Product Description popup.authors popup.nrat_date 2024-01-01 Close
