Abstract
In order to solve the problem of roadway maintenance with staggered layout under the geological conditions of close-distance coal seam,taking the auxiliary haulage gateway of 3S203 working face as the engineering background,on-site investigation and theoretical analysis methods were used to analyze the tunnel deformation mechanism of the 3S203 auxiliary transportation road during mining:the interval between layers is too small and there is no key layer;the offset distance of the 3S203 auxiliary transportation road arrangement is unreasonable.An optimized joint support plan of hollow grouting anchor cable+one beam and three pillars is proposed.After field application and monitoring,this joint support plan controls the maximum roof displacement within 200 mm,and the maximum pressure of roof anchors and cables with in 110 kN.The joint support design well controls the deformation of the roadway.关键词
