Abstract

The article presents an analysis of the quality of coal mined and transported from the wing of the mine field. The impact of the gross transportation of rock from mining along with mined coal, as well as part of the rock that is cut in the cleaning hole on the quality of marketable products, is determined. The structure of the influence of each of the above factors on the overall quality of products is determined. Based on the analysis of the quality of the company's products, it was concluded that the rock that is directly cut in the cleaning hole has a significant impact on the quality of the extracted commodity products. The article suggests the use of separate extraction and transportation by one transport chain of coal and rock with their further separation in the surrounding yard. Defined requirements for mining equipment. The proposed mining technology. The obtained results allow us to outline further research that will be covered in the authors' next works.

Keywords: coal mining, coal quality, separate extraction of coal, rational parameters
