摘要
针对陈四楼煤矿21603轨道巷局部坡度30°、煤层厚度变化频繁、且处于瓦斯异常区等极其复杂的地质条件,经过分析对比掘进方案,确定采用综掘机攀爬过大坡度段、优化支护设计等综合措施进行巷道掘进与支护,实现了安全、高效掘进,并突破性地实现了大坡度段综掘机的攀爬。
For Chensilou coal mine 21603 local roadway slope track transportation tunnel in 30°, coal thickness changes frequently, and in the gas anomaly area, extremely complicated geological conditions, by selecting analysis contrast construction plan, breakthrough to achieve the comprehensive tunneling machine to climb,roadway supporting design and timely change, reducing the support costs, safe and efficient driving is realized.
