摘　　要：为解决松散煤层巷道支护难题,以淮北矿业集团涡北煤矿8100机巷为研究对象,对未补强和采用双排锚杆补强技术的U型钢支架承载能力进行理论的结构力学分析,得到了未补强和采用补强措施后的U型钢支架的内外边缘应力。研究表明:采用补强措施的U型钢支架的内外边缘应力显著降低,支护效果明显增强。To solve the problem of loose coal seam roadway support,the research object is 8100 machine lane of Huaibei mining group vortex north mine, analysis the structural mechanical of the load carrying capacity of U-shaped steel supports for unreinforced and two-row anchor reinforcement technology is carried out, the inner and outer edge stress of the U - steel bracket is obtained without the reinforcement and the reinforcement measures.The research has shown that： the supporting effect is obviously enhanced of the U steel frame with reinforcing measures of inside and outside edge stress significantly reduced.
