Abstract: In the process of underground mining, the composite roof support technology in the underlying seam of the short distance
coal seam plays a very important role. The progressiveness and application effect of this technology will have an important impact
on the quality, efficiency and safety of production. Therefore, combined with the current underground actual mining situation, this
paper analyzed the reasonable selection of the roadway location in the underlying seam of the short distance coal seam, and
determined the reasonable support scheme and quality control measures of the composite roof support technology in the underlying
seam of the short distance coal seam, and analyzed the application effect and benefits of the support technology in the actual
mining, which provides a certain reference for the development of roadway roof support technology in the later stage.

Key words: short distance coal seams; composite roof; bolt and truss support
