摘　　要：通过对采区边角煤开采现状分析,结合工作面地质条件,根据开采后残留的边角煤块段形状,探索了旋转开采、台阶开采、梯形开采、带采煤柱开采、房柱式开采等有针对性的边角煤开采方案,从而形成了边角煤开采的块段布置模式。The mining status of boundary coal-pillars is analyzed.In Combination with the mining geological conditions,according to the shape of residual part of the boundary coal-pillars,some aspects are researched,such as the rotating mining,steps mining,trapezoid mining,belt coal pillar mining,room and pillar mining,which were contraposed to the mining method of boundary coal-pillars,thus forming a section layout pattern of boundary coal-pillars.
