Abstract Coal was one of the most basic fossil energy currently for human. Ground handling of large amounts of coal waste that produced in the process of coal mining has brought great harm to the environment. To the coal mine enterprises, large gangue lifting, invalid transportation and ground washing caused a great waste of resources. While filling mining needs substantial materials from ground to well. So it was of great significance to discharge refuse under the shaft. Based on the full research to crushing, screening, washing, dehydration, transportation, storage and each link of coal washing underground, the successful implementation of discharging refuse with jigging under the shaft has generated huge economic and social benefit.
