孤岛工作面沿空掘巷煤柱宽度及其加固技术研究
Research on coal pillar width and its reinforcement technology of gob-side entry driving at insular face
摘要
Abstract
In order to obtain a small coal pillar width and reinforcement techniques of the gob-side entry driving at the island face 1116( 1 ) , the coal pillar width and reinforcement form which influence the stability of coal pillar were analyzed according to the character of roadway surrounding supporting, software of FLAC with six simulation programs. The results show that the reasonable width of a pillar is 8 meter long; an anchor beam, gunning and grouting can effectively control the small pillarg deformations to keep a coal pillar safe and stable. Research achievement was put into practice successfully, and made a great reference to similar roadway stabili- ty control in Huainan mining area.关键词
