介绍了EBZ260W型小断面岩巷掘进机的主要设计特点、技术参数和掘进巷道施工工艺,通过井下工业性试验,表明EBZ260W小断面全岩巷掘进机施工瓦斯抽排放巷道可以有效提高进尺速度,保证安全,为小断面岩巷掘进机的推广应用奠定了基础。
The main design features and technical parameters of EBZ260W tunneling machine with small section and roadway construction technology are introduced. Through downhole industrial tests, it is shown that the EBZ260W small section full tunneling machine can effectively increase the footage-in-levee when it is used for tunneling. Safe, and laid the foundation for the popularization and application of small section rock tunnel boring machine.
