摘　　要：本文以郑州矿区"三软"煤巷为工程背景,分析了锚网支护在软岩巷道支护中的作用机理,利用UDEC数值模拟软件研究了郑州矿区煤巷锚杆支护不同锚杆长度、锚固长度、支护密度下的应力分布规律。白坪煤矿22031上付巷现场实测表明,上述支护参数能够满足安全生产要求。Taking the"three soft"coal roadway in Zhengzhou mining area as the engineering background,the paper analyzes the role of anchor net support in soft rock tunnel,and numerical simulation software is used to study the distribution regularity of stress of anchor bolt support in Zhengzhou coal roadway under different length,anchor length,anchor supporting density etc.The field test on the roadway of 22031 in Baiping Coal Mine shows that the above supporting parameters can meet the requirements of safety production.
