摘要
Abstract
To solve the problem of coal roadway deformation in soft rock conditions with dynamic pressure influence in Chahasu coal mine, this research was made on the supporting practices in auxiliary equipment remove gateway, combined the theories and field measurement methods, the floor heave mechanism under the influence of mining activities was analyzed and improvement support projects were designed. The study result shows that it was expansion-flexural composite of floor heave and the deformation mechanism was determined as IABC IIBD IIIC, and“blot-mesh-anchor-steel band-shed” coupling supplement support system is proposed to reinforced support. The site monitoring result shows that it can effectively control the volume expansion of floor heave at the roadway bottom and it provides experience for support optimization under the similar condition.关键词
