摘要: 主要分析了复合顶板巷道的薄弱部位,以A矿南翼大巷4309为试验基地,在充分调查研究后,针对该部分巷道
支护措施,对使用锚杆支护及锚杆与锚索联合支护的两种支护状态下巷道的情况进行数值模拟。结果表明:效果最好的
为锚索锚杆联合支护,该支护技术能够有效降低巷道变形量,并且为以后煤矿复合顶板巷道的支护技术奠定了基础。

Abstract: This paper mainly analyzed the weak parts of the composite roof roadway. Taking 4309 roadway in the south wing of A
coal mine as the test base, the roadway condition numerical simulation of anchor bolt support and combined support with anchor
rod and anchor rope was made under two kinds of supporting conditions in this paper. The results showed the best effect was
combined support with anchor rod and anchor rope, and the supporting technology can effectively reduce the deformation of
roadway and laid a solid foundation for support technology in composite roof coal mine roadway.

Key words: coal roadway; composite roof; numerical simulation; supporting technology
