摘要: 针对山西乡宁焦煤集团台头前湾煤业有限公司高应力松软破碎巷道的实际工况,选用了“锚网+U型棚”支护
技术,并对该支护技术的理论基础进行了分析,详细阐述了支护施工过程。实践应用表明,该支护技术能有效地控制巷
道围岩的变形,巷道位移量小,具有很好的经济效益。

Abstract: In view of the actual working conditions of the high stress soft and broken roadway in Taitou Qianwan Coal Industry
Co., Ltd. of Shanxi Xiangning Coking Coal Group, this paper choosed the support technology of "anchor net+U-shaped shed",
analyzed the theoretical basis of the support technology, and elaborated the support construction process in detail. Practical
application shows that the support technology can effectively control the deformation of the surrounding rock of the roadway, the
displacement of the roadway is small, and it has good economic benefits.

Key words: anchor net+U-shaped shed; high stress; soft and broken roadway; support technology
