摘要
Abstract
taking the instability and destruction of large cross-section tunnel in Yangchangwan coal mine for example,the analysis shows that the reason of instability and failure of large cross-section roadway is the external load induced by local deformation.The paper proposed the preventive measures and rational layout parameters of roadway support.The application on-site of the support technology shows that the deformation of the roadway is effectively controlled and this technology has a certain reference value for determining support program under the similar condition.关键词
