复杂地质条件下煤矿掘进支护技术的应用

Application of Coal Mine Excavation Support Technology under the Complex Geological Condition

基于煤矿掘进地区的地质条件,分析了煤矿掘进的技术难点,同时介绍了复杂地质条件下的煤矿掘进支护技术,包括支护临界点的确定、综握机的选型、支护体系的建立、综掘机的配套系统和施工组织管理。由分析可知,在复杂地质条件下,应严格按照预设方案进行掘进支护施工,以取得好的支护效果。

Based on the geological conditions of coal mine excavation area, this paper analyzes the technical difficulties of mine excavation, and introduces the complex geological conditions of coal mine excavation supporting technology,including supporting critical point determination, fully hold machine selection, support system, supporting system of roadheader and the construction organization management by analysis. That, in complex geological conditions, should be strictly in accordance with the preset scheme of excavation and supporting construction, in order to obtain a good supporting effect.
