Abstract
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.关键词
