蒲白黄陵新区矿井巷道快速掘进关键技术

Key technology for rapid excavation of mine roadway in Pubai Huangling new area

为解决深部复杂地质条件下煤巷快速掘进技术难题,缓解矿井采掘接续矛盾,文中以蒲白矿业黄陵新区生产地质条件为基础,基于先进掘锚一体化快速掘进设备为核心,从巷道快速掘进机械化设备选型、配套方案设计、设备适应性改造、支护参数适用性优化设计、施工工艺及劳动组织优化设计5方面内容出发,建设巷道掘进工程中“掘—支—运”整个流程的煤巷快速掘进系统。通过蒲白黄陵新区矿井巷道快速掘进关键技术研究,科学设计适合该复杂地质条件的快速掘进掘锚一体化系统长度为67 m,系统最终可将月进尺水平提高到每月500 m左右,达到提高巷道掘进速度,降低掘进作业劳动强度,减人提效的目的。研究实践对于深部复杂地质条件下快速掘进关键技术研究具有一定参考价值。

In order to alleviate the contradiction between mining and excavation, the rapid excavation technology of coal roadway under deep and complex geological conditions is studied.Based on the production geological conditions of Huangling new area of Pubai mining industry company and taking the advanced excavation anchor integrated rapid tunneling equipment as the core, the coal roadway rapid excavation system with the whole process of “excavation-support-transportation” in roadway excavation engineering is proposed from five aspects of excavation equipment selection, supporting scheme design, equipment adaptability transformation, support parameter optimization, and construction technology and labor organization optimization design.Through the research on the key technologies of roadway rapid excavation, it is determined that the length of the rapid excavation anchor integrated system suitable for the complex geological conditions is 67 m.The system can finally increase the monthly footage level to about 500 m, so as to improve the roadway excavation speed, reduce the labor intensity of excavation operation, decrease personnel and improve efficiency, which has certain reference value for the research on the key technology of rapid excavation under deep and complex geological conditions.
