Improving the process of coal extraction based on the parameter optimization of mining equipment

The aim of this paper is to develop and validate methods of
choosing the means of the mining face mechanization. This paper analyses
existing methods of optimizing processes in mining. It was established that
the effectiveness of the performance map of coal field is formed by a group
of technological, operational, and economic parameters which can be
represented as a vector of solutions. To find the optimal solution, it was
suggested to use network models and graphs. The essence of the technique
is to represent the input and output (production level, prime cost) resource
flows in an organized structure. Regularities of forming technological
schemes of coalfield operation with a given level of performance, taking
into account the relationship between technological parameters of mining
face, operational parameters of the stoping equipment, technical and
economic performance are defined. We developed the system for decision-
making support, which allows optimizing operational parameters, reducing
the production prime cost, and selecting the structure of the mechanized
complex of stoping equipment with a specified level of performance. This
paper describes approaches that can be used at the design stage of mining
face and in the process of operation.
