Abstract:

Purpose. To develop the method of determining of the settler pond volume of the main dewatering plant of a coal mine to improve the energy efficiency of its work.

Methodology. In order to obtain the scientific and practical results the methods of operations research and analysis of technological processes have been used.

Findings. The efficiency of use of the main dewatering plant of the coal mine as an efficient controllable load has been substantiated. The technological conditions allowing us to improve the energy efficiency of the coal mine pumping in the process of regulation of electricity consumption modes have been defined. The analysis of the technological parameters of the acting main dewater-ing plant has been done.

Originality. The method for determining the settler pond volume of the main dewatering plant of the coal mine, which improves the efficiency of regulation of the electricity consumption modes, has been developed. We have obtained the dependences of the settler pond specific volume per 1 m3 of water inflow on the amount of its branches and condition of their uniformity.

Practical value. The increase of the number of settler pond branches over five results in inessential reduce of its specific volume but significant complication of the tech-nical plan and construction process. We have substantiated the expediency of building equal in volume branches instead of the unequal ones. This reduces the settler pond volume required for purposes of regulation of the electricity consumption modes in the average by 10–15%.
