摘要： 山西兰花沁裕煤矿的巷道采用放炮掘进，15^#煤层胶带大巷与15^#煤层东翼轨道大巷的立体交叉点位于地质构
造处，巷道的稳定性容易受放炮的影响。为了增强立体交叉处巷道的稳定性，在15^#煤层胶带大巷交叉段铺设混凝土盖
板，而在15^#煤层东翼轨道大巷交叉段采用U 型棚式支护。介绍了立体交叉处的施工方案和安全措施，可以为相似条件
下巷道支护的施工提供参考。

Abstract: The roadway of Qinyu Coal Mine of Shanxi Lanhua Group is excavated by blasting. The three-dimensional intersection
of the belt roadway of 15^# coal seam and the track roadway of the east wing of 15^# coal seam is located in the geological structure,
and the stability of the roadway is easily affected by blasting. In order to enhance the stability of the roadway at the intersection,
Qinyu Coal Mine laid the concrete cover plate at the intersection section of the belt roadway in the 15^# coal seam, and adopted the
U-shaped shed support at the intersection section of the track roadway in the east wing of the 15^# coal seam. This paper
introduced the construction scheme and safety measures of the three-dimensional intersection, which can provide reference for the
construction of roadway support under similar conditions.

Key words: blasting excavation; large section roadway; geological structure; three-dimensional cross support
