摘要： 在概述A 煤层地质条件及存在较多煤线和夹矸、稳定性较差的基础上，对原U 型棚支护结构的弊端进行了分
析。结果表明，该煤层巷道断面大，两帮软弱，动压使巷道冒顶的可能性大。经过深入分析及对同类型矿井的调研，提
出了符合该煤层工作面巷道实际情况的新型锚网索支护方案。监测结果显示，新型锚网索联合支护方案的实施，成功解
决了该煤层复合顶板支护的技术难题。

Abstract: On the basis of summarizing the geological conditions of A coal seam and the existence of more coal lines, more
gangue and poor stability, this paper analyzed the disadvantages of the original u-shaped shed supporting structure. And it turned
out that the roadway in this coal seam has a large section and the two sides are weak, the possibility of dynamic pressure causing
the roadway to fall to the roof is so big. A new type of bolt-mesh-anchor support scheme was put forward, which accords with the
actual situation of the roadway of the working face in this coal seam through in-depth analysis and investigation of the same type
of mines. The monitoring results show that the implementation of the new combined support scheme of bolt -mesh -anchor
successfully solved the technical problem of the composite roof support in this coal seam.

Key words: composite roof; bolt-mesh-anchor; combined support
