| 摘 要： | 针对常村矿回采巷道变形严重,影响正常生产的问题,通过对矿井赋存条件、巷道现有支护形式和围岩变形过程分析,采用新型联合支护技术对S6-11回风巷道支护进行优化。现场实测巷道顶底板相对移近量最大120mm,两帮相对移近量最大140mm,均在允许正常范围之内。

| Abstract: | In view of the serious deformation of the mining roadway in Changcun Mine,which affects the normal production,through the analysis of the existing conditions of the mine,the existing supporting forms of the roadway and the deformation process of the surrounding rock,the new combined support technology is adopted to optimize the support of the S6-11 return air roadway.According to the field measurement,the maximum relative displacement of roadway roof and floor is 120mm,and the maximum relative displacement of two sides is 140mm,both of which are within the allowable normal range. |
