More Information
Summary:The invention discloses a combined supporting structure and method for an underground phosphorite complex section. The combined supporting structure comprises supporting mechanisms, a flexible net and a pipe seam anchor rod, the flexible net is supported through the multiple supporting mechanisms, a spiral mechanical top drives an upper support to ascend and descend so as to adjust the height of the flexible net, in the ascending process of the flexible net, a semicircular ball head piece uses the upper end of a sleeve as a fulcrum, an elevation moving upward is formed to adjust the contact surface between the flexible net and a mine top plate, the pipe seam anchor rod penetrates through the flexible net to be anchored with the mine roof, so that the combined supporting structure is suitable for different mine roof structures, support can be quickly formed, collapse of the mine roof is avoided, and the construction is simple and convenient. 一种井下磷矿复杂地段的联合支护结构及方法，它包括支撑机构、柔性网和管缝锚杆，通过多个支撑机构支撑柔性网，螺旋机械顶驱动上支撑升降调整柔性网
