Ustification of ore cargo flows from the quarry working area to the CСT transshipment points for their management at the next stage of quarry development in the event of a lack of initial data.
popup.description2
The main factor determining the development of quarry transport is the constant deterioration of mining and technical conditions of development: an increase in the height of the working zone and the distance of transportation due to the deepening of the quarry and an increase in its size. During the delivery of ore from deep horizons of quarries, improving the formation of ore flows reduces the impact of negative phenomena due to their rational distribution on the DPP. In this regard, it is planned to develop a methodology for predicting ore flows in a quarry, taking into account the volume of ore being transported. In addition, one of the rational ways to reduce the cost of quarry development is its phased development in the design contours. For this, the development of the quarry is divided into stages. The parameters of the intermediate contours of the quarry are determined during the transition from the actual position to the design contour, which affects the size of the working zone. The determination of cargo flows for the design DPP, which should serve the lower part of the horizons of the working zone, is carried out by forming schemes for delivering ore from deep ledges of the quarry to this DPP. The distance of ore transportation by road is calculated using a mathematical model that takes into account the function of ore distribution by depth, based on the experience of using approximation in mining, which describes the change in ore volumes from the depth of the mining horizon. In the case of ore flows forming on the DPP, there is a need to assess its loading in prospective conditions. In this case, the determination of the design ore flows on the DPP in the quarry is carried out taking into account the error caused by a possible deviation in the calculation of the amount of reserves. The use of this methodological approach will help to justify the rational distribution of ore flows between several DPPs.
