摘要
以斜沟煤矿23108工作面材料巷外段为对象,基于工程地质条件设计采用锚杆、锚索、钢带、金属网支护作为永久支护,并对锚杆长度、直径、间排距和锚索间距等技术参数进行了计算分析。矿压观测结果表明:巷道顶板、底板、两帮的变形量较小,巷道围岩得到了有效控制,巷道支护方案合理。
Taking the outer section of material roadway of the 23108 working face in Xiegou Coal Mine as the object,bolt,anchor cable,steel strip and metal mesh support are used as permanent support based on engineering geological conditions,and the technical parameters such as bolt length,diameter,row spacing and anchor cable spacing are calculated and analyzed.The observation results of mine pressure show that the deformation of roadway roof,floor and two sides is small,the surrounding rock of roadway is effectively controlled,and the roadway support scheme is reasonable.
