针对宏景塔一矿浅埋深大采高工作面回采巷道联巷的具体地质特征,提出了锚梁网索联合支护的方案,并采用有限差分数值计算程序FLAC2D5.0对支护效果进行了较深入的分析。结果表明:巷道采用联合支护技术是合理的,所选定的支护参数完全能够满足工作面安全需要,可为类似条件下的联络巷道支护提供理论依据。
Aiming at the geological characteristics of the gateway of mining gateway in Hongjingta Mine, the scheme of combined support of anchor beam and cable network is put forward and the support effect is carried out by FLAC2D5.0 finite difference numerical calculation program A more in-depth analysis. The results show that it is reasonable for the roadway to adopt the united support technology. The selected support parameters can fully meet the safety requirements of the working face and provide theoretical basis for the support of the contact roadway under similar conditions.
