摘要
以南屯矿薄煤层3602工作面轨道、运输顺槽为工程背景,通过对沿空留巷大变形特征分析,提出了沿空留巷的支护方法,确定了合理的巷内支护形式和参数。工程实践表明,该支护手段效果显著,保证了所留巷道的稳定,达到了预期要求。
Taking the track,haulage gate in Nantun Coal Mine thin coal seam 3602 working face as the engineering background,through the analysis of roadway deformation characteristic,gob-side entry retaining method is presented in this paper,the reasonable roadway supporting form and parameters are determined. Engineering practice shows that the means of support effect is significant,which retains roadway stability,reaches the expected requirements.
