| Abstract: | Based on the practical observation data of the roof fall in mined area at Xishimen Iron Mine,two kinds of models for roof fall,namely "inflator" and "surrounding flow",are proposed. Through detailed calculation and analysis of "surronding flow" model, the safety distance of avoiding the danger of striking airstream is obtained and technical measures for controlling the roof fall in mined area are suggested. |
