摘要
通过对翟镇煤矿 3 4 0 1高档普采面运巷顶板结构分析 ,确定了锚杆支护参数并进行了试验研究 ,巷道经历了静、动压过程 ,巷道变形量符合设计要求 ,试验取得了成功 。
This paper analysed the roof construction of transport roadway in3 40 1 conventional working face and determined the bolting parameters.The tested roadway was influnced by static and dynamic pressure.The flexibility of roadway is coincidence with the design
