    • Abstract
  • The high-pressure sluice wall in 21102 working face in a coal mine was built in 2002, and put into use in 2003.The water pressure of high-pressure sluice wall reduced from 7.55 MPa to 6.7 MPa. It was uncertain that if the high-pressure sluice wall could resist the water pressure.This paper used methods of theoretical calculations, FLAC3D numerical simulation, concrete quality testing and pipeline anti- pressure situation to study the the safety of the high-pressure sluice wall.
