Abstract:

Purpose. To identify features of formation of cargo flows in the nodes of complicated transport links without and with speed control belt conveyor systems and to use these features to improve the energy efficiency of conveyor transport.

Methodology. Statistical analysis methods and matrix theory were used to find the value distribution of cargo flows in the nodes of the conveyor network. Theory of Markov processes was used to describe the flow of working faces and for simulation.

Findings. The method of determining the probability density of traffic flows in the nodes of mine conveyor network using speed control of conveyor belts with known distribution laws the flow of coal at each working face. The dependencies and algorithms, which prove an additional reduction of energy consumption by using variable speed drive on conveyor chains, were obtained.

Originality. For the first time, it was proved that the regulation of belt speed on multiple conveyor chain brings an additional reduction of energy consumption by increasing the operating time with a minimum speed of each subsequent conveyor wherein energy dependence of growth on the number of conveyors with frequency inverters is exponential with negative exponent. It was also proved that a decrease in length of the first conveyor in the chain, this effect is reduced.

Practical value. The proven dependencies make it possible to determine optimum installation position for variable speed drives on the main mine conveyors with a limited number of frequency converters. The proposed algorithms and analytical models with the appropriate information provision allow producing real-time control energy efficient transport lines, including conveyor systems with variable speed drive.
