Abstract
Taking 109 track lanes of a coal mine in Huaibei as researth object, elastoplastic model of the roadway destruction was constructed and displacement solution of internal surface of surrounding rock was drawn.Then, the track roadway bolts were grouted, through field measurement, it was concluded that anchor grouting can improve the strength of the broken rock to improve the nature of the rock mass, and efficiently control the deformation of surrounding rock. The change mechanism and stress change of surrounding rock of roadway under the influence of mining were systematically analyzed,providing advice for subsequent roadway support and governance under similar conditions of the mine.关键词
