ACTIVE MULTIDIMENSIONAL CONTROL OF RAPID DEFORMATION INSTABILITY OF A COAL ROADWAY IN A DEEP MINE

In this paper, based on the rapid deformation instability characteristics and active control principles of the surrounding rocks at a coal roadway in Xingdong mine, the displacement and stress fields of the surrounding rocks are calculated by using FLAC, and the main factors leading to deforming and failing of the surrounding rocks are analyzed. Moreover, according to new support principles, the combined cable truss support system is studied, which can provide compressive stress support in horizontal and plumb directions, and the responding support parameters are optimized and determined. The field measurement results show that the cable truss support system works reliably to prevent the dangerous deformation and roof caving accident.
