摘要
针对武钢程潮铁矿采准巷道净断面尺寸增大、巷道稳定性下降的状况 ,采用数值计算方法对程潮铁矿巷道支护方案进行优化计算 ,并给出合理的支护方案。
In view of the increase of the final cross-section of preparatory workings and the decrease of the workings stability, the numerical calculation method was used to optimize the calculation of the supporting method and find out the rational supporting scheme.
