Technical Field

The utility model relates to the field of coal peeling machines, in particular to a stable and reliable coal peeling machine in a coal mine.

Background

The underground water of the coal mine can be wrapped with a large amount of coal in the flowing process to form water coal with the coal content of 10% -20%, if the water coal is directly discharged into a water sump at the bottom of the coal mine without treatment, the water sump section can be reduced after long-time siltation in the water sump, and the water storage capacity of the water sump can be reduced.
