摘　　要：张双楼矿74102工作面内主采的7#煤层与下伏9#煤层存在合成情况,探明复合区内煤厚变异系数较大。为保证资源采出率,根据74102工作面地质情况,确定了基于不同煤层的分层错巷开采方法,提出了以聚酯纤维柔性网作为人工假顶保证下分层回采时护顶效果,可为类似地质条件下的复合煤层回采技术选择提供参考借鉴意义。There are syntheses between 7#coal seam and 9#coal seam in 74102 working face of Zhangshuanglou Coal Mine.It is proved that the variation coefficient of coal thickness in the composite area is large.In order to ensure the recovery rate of resources,according to the geological conditions of 74102 working face,the mining method of layered staggered roadway based on different coal seams is determined,and the effect of roof protection is put forward by using polyester fiber flexible net as artificial false roof,which can provide reference for the selection of mining technology of composite coal seam under similar geological conditions.
