摘　　要：平煤股份十二矿为突出矿井,采用先开采保护层工作面,被保护层工作面采用回填液压支架和普通掩护式液压支架,在回收过程中顶板支护难度较大。在回填液压支架段采用锚网索支护的方法控制顶板,通过对回填液压支架的长度、锚网索间排距的技术研究,探索出利用锚网索技术对回收期间的顶板控制的方法,为不同型号液压支架在回收期间顶板支护技术找到新途径。No. 12 coal mine of Pingmei is an outburst mine. It is difficult to support the roof in the process of recovery by first mining the protective layer face, backfilling hydraulic support and common shield hydraulic support in the protected layer face. In the backfill hydraulic support section, bolt-mesh-cable support is used to control the roof. Through the technical research on the length of backfill hydraulic support and the row distance between bolt-mesh-cable, the method of roof control during the recovery period is explored by using bolt-mesh-cable technology, and a new way is found for the roof support technology of different types of hydraulic support during the recovery period.
