摘要
针对屯兰煤矿12510工作面运输平巷大断面软岩巷道支护特点,采用实践分析和数值分析手段,对原支护设计进行优化,确定了合理的支护参数。现场实践表明,采用优化方案后,巷道顶、底板移近量和两帮移近量分别为115mm和106mm,支护效果良好,能够满足生产使用。
According to the support characteristics of large section soft rock roadway in the 12510 working face of Tunlan Coal Mine,the original support design was optimized by means of practical analysis and numerical analysis,and the reasonable support parameters were determined.Field practice shows that after adopting the optimized scheme,the roof-to-floor convergence of the roadway and the convergence of two sides are 115mm and 106mm respectively,and the supporting effect is good,which can be applied to production.
