| description |
The local meteorological elements are connected with technical, economic and social parameters of the opencast atmosphere. The goal of
this paper is the realization of methods and the developing of software for the calculation and visualization of the distribution of
contaminations in the quarry atmosphere based on a simulation study for the dynamics of moving air masses in the opencast space. The
environmental impact of mining dust spreading on the concentration of pollutants has been described. Quarry aerology for open-pit mines
exploits applications of the theory of functions of complex variables for computing concentration of harmful substances and convective
airflows in the local space. The software system for calculation of gas-dynamic parameters in the opencast atmosphere has been developed
in the Delphi environment and tested at the calculation of natural ventilation in open-pit mine. The usage of a single vortex method allows
creating effective design models, which possess a withstandability of systems of the algebraic equations to define the air-stream velocity
in magnitude and in direction at any point of the mine. The algorithm of this method is modified for a task of the simulation study of
the mine’s space. The problem solution was made on the basis of the mine’s designed profiles for 2010 and 2015 built with taking into
account prevailing directions of the wind (North, South, West, East). After the velocity field calculation on the basis of the preset
information about the location of harmful condition sources is computed the concentration pattern of harmful conditions. By the results of
calculations for such fields, by the interpolation of values between the mine’s profiles, as a whole, is determined the condition of
contamination in the opencast atmosphere. Calculating data on harmful substances distribution in the local atmosphere have allowed
determining the contours and volumes of zones in the quarry. The developed program and methodical complex allows performing on-line
computation for hydrodynamical fields, and simulating on their basis a change in powder-gas conditions in the opencast. At that the
development of mining operations is considered, as well as the evaluation and prediction the condition of air contamination in the
environment atmosphere at the area of operations of the works. The results of calculations may be used for creation an ecological GIS of
the mining-and-processing integrated works and for the designing a forced ventilation of mines. The further development of this project is
the creation of an intellectual system for decision-making in real time, so that to reveal and neutralize the dangerous areas in respect of the
factor powder-gas at workplaces in deep opencasts. |
