ABSTRACT: This paper presents a new approach for mitigating high tower structures slope based on the foundation grouting reinforcement (FGR) mechanism. Three effects of the FGR approach were analyzed: the reinforcement provided by grouting to improve

Longwall extraction of coal seam disturbs the whole overburden strata, from the coal seam to the surface, and forms a subsidence basin. This paper investigated the mechanism of the overburden strata bending deformation, the alluvium mechanical parame
