Abstract: With the gradual depletion of shallow coal resources, the depth of coal mining will increase, and the mining equipment will gradually become larger and more heavy. The existing shaft lifting system will not be able to meet the overall lifting requirements of large equipment, so it is large in the underground. Equipment assembly stations and dressing stations are becoming more and more popular. This paper takes the large-scale equipment assembly station in Licun Coal Mine as an example to discuss the design and innovation of underground assembly station and dressing station.
