摘要
在煤矿巷道支护工作中U型钢棚支护技术拥有十分明显的优势。叙述了2801工作面的工程概况,探讨了掘进巷道利用钢针过地质构造段中的支护技术及U29型棚与顶板钢针支护技术。
U-shape shed supporting technology has obvious advantages in the coal mine roadway support work. This paper described the general situation of the project of 2801 working face, and discussed support technology used in passing through geological structure sections in tunnelling roadway by using steel needles and supporting technologies with U-shape shed and roof steel needle.
