Improvement of quarry and slagheap reclamation technology

This paper considers and analyzes a relevant issue of treatment of disturbed soils. The equipment to carry out various processes of mining reclamation of waste heaps and quarries with a significant reduction in the level of environmental risks through the operation of an energy-saving small-sized apparatus has been designed. The use of the developed soil reclamator is also adequate for pre-sowing and other types of agrotechnical tillage, plant care in agricultural fields, as well as in areas with a heterogeneous landscape. The functionality of the unit is able to provide energy autonomy and automation of the technological process. The low weight of the device makes it possible to reduce the pressure on the soil, which minimizes the environmentally hazardous formation of dust during the treatment of waste heaps, the destruction of its structure, the machine degradation of the fertile layer during the processing of all types of territories. The device also reduces the risk of fertile soils slipping from the slopes of mine dumps due to the fact that the soil reclamator is self-propelled and functions without the need to involve a heavy tractor. The mathematical modeling of the operation of the proposed technical support for the treatment of waste heap reclamation in comparison with the opposed analog proves the ecological and economic efficiency of the eco-adaptive soil reclamator. The average value of profit ratios, when using the proposed soil reclamator, is 121.82 % higher than with the involvement of opposed equipment. Indicators of the negative environmental impact of the designed equipment are 100 % lower than the environmental impact when operating the analog. The proposed technical solution can be effectively applied both in schemes of sanitary cleaning of settlements, and in the process of modernization of agricultural machiner
