    • Abstract
  • The expanding tunneling technology of large section open - off cut coal cutters is used at the 1703 fully-mechanized caving face in Honghui First Coal Mine of Jingyuan Coal Group Co., Ltd., This technique not only shortens the time of removing face, but also reduces the labor intensity of workers, improves the work efficiency, and its economic benefits is very remarkable.
