南关煤矿施工底锚杆底鼓治理实践

摘要

Taking the 3206 transport lane of Nanguan coal mine as the background, this paper introduces the present situation and existing problems of the mine roadway floor heave treatment, combined with the action mechanism of the bottom bolt, determines the reasonable supporting parameters, and carries out the industrial test in the 3206 transportation roadway. It is feasible to analyze the construction quality of anchor rod and the near displacement of roof and floor of roadway, and to determine the method of using bottom bolt to deal with the bottom heave in Nanguan Coal Mine.%以南关煤矿3206运输巷为背景,介绍了矿井巷道底鼓治理现状及其存在的问题,结合底锚杆的作用机理,确定了合理的支护参数.通过在3206运输巷进行工业性试验,分析锚杆施工质量及巷道的顶底板移近量,确定在南关煤矿采用底锚杆进行底鼓治理的方法是可行的.
