摘　　要：针对长平公司Ⅲ5308双巷工作面的煤层结构复杂,存在作业安全隐患等问题,结合巷道地质、构造条件,根据其煤岩技术特征及四邻采掘情况,利用普氏和自然平衡拱理论对支护参数进行校核计算,巷道采用高强度锚杆、锚索等联合支护方法进行支护。计算得出了Ⅲ5308双巷工作面的具体支护参数,绘制了工作面两巷及端头支护示意图,从而指导工作面的支护作业。校核结果表明,巷道顶锚杆、巷帮锚等支护参数满足工作面生产需求,为巷道工作面掘进提供了可靠性和良好的应用效果。In view of the complex structure of coal seam and hidden danger of operation in the workface of Ⅲ5308 roadway of Changping Company, combined with the geological and structural conditions of the roadway, the supporting parameters are calculated by using the natural balance arch theory of Pu Shi according to the technical characteristics of coal and rock and the mining conditions of the four adjacent areas. The roadway is supported by high-strength bolt,anchor cable and other combined support methods. The specific supporting parameters of the working face of the Ⅲ5308 roadway are calculated and the schematic diagram of two lanes and end support of the working face is drawn, so as to guide the support operation of the working face. The results show that the supporting parameters such as roof bolt and side anchor meet the production demand of working face, and provide reliability and good application effect for tunnel face excavation.
