【 摘 要 】

A new trend for designing powered supports for thick coal seam mining with controlled coal discharge is substantiated. Numerical modeling for gravity flow of disintegrated rocks and the flow interaction with the support section is performed. A test bench is developed, and the laboratory studies into coal discharge process are carried out.
