DETERMINATION OF FIELD BOUNDARY PARAMETERS IN DRILLING AND BLASTING PROCESSES IN OPEN PIT MINES

This article is from examples adapted to geological and geotechnological modeling in mining enterprises operating and drilling costs and the results of using several methods to increase productivity in some mining operations and drilling-blasting processes. The main goals and objectives of this article will be to reduce the number of drilling and blasting holes in mines and increase the blasting area. The cost of these objectives from an economic point of view is, firstly, directly proportional to the number of boreholes, and secondly, the associated increase in the extent of the blasting area. In the mines indicates an indirect effect on the recovery efficiency of the target material associated with excavation and blast damage. Therefore, drill strings, detonators, and detonators in the mine will be more about the problem of the boundary of the blasting area and create conditions for less drilling. During blasting and drilling processes in mining enterprises the main problem in creating an accurate surface model is that the mass of the cover rock is usually relative to the mass of the blasted area will be widely spaced. Coarse samples are obtained by drilling blast holes. So interpolation sufficiently exceed local variations in the underlying geology. Created in a mine borehole measurement reliable determination of geological boundaries in the field in real time data, we posed a local model estimation problem in an adaptive sampling system. The selection strategy based on the proposed information will consist of two stages. First, blast holes in mines are selected in a way that is adapted to the geology of the drilling and to obtain the maximum benefit in terms of their location. Mine blasting processes will consist of a step-by-step improvement of the spatial model. The second stage drilling-blasting processes in the mine depend on the forecast conducts expert-guided drilling at predetermined distances from geology and geology and in order to optimize the explosion, it is necessary to reduce its limit in order to reduce its damage.
