摘要
Abstract
The loading process of F15-31020 belt conveyor entry in No.4 Colliery of Pingdingshan Coal Group Company was carried out with FLAC3D. The results showed that convergence between roof and floor and convergence between two sides was respectively 0.8 m and 0.9 m during the ifrst mining inlfuence, and the former two was respectively 1.1 m and 1.05 m during the second mining inlfuence. The numerical simulation result shows that gob-side entry retaining of F15-31020 belt conveyor entry is practicable.关键词
