摘要
分析了巨厚冲积层薄基岩高应力破碎顶板条件下工作面地质条件及支护原理,根据支护效果总结此类地质条件下大断面切眼一次成巷工作经验,为类似条件下实现大断面一次成巷快速掘进提供了有益尝试。
The face geological condistions and the supporting principle in the thick and thin alluvial bedrock under the conditions of high stress and broken roof are analyzed.According to supporting effects,the experience of full completed drifting under such geological conditions is summed up.A useful attempt is provided for fast drivage in full completed drifting at large section under similar conditons.
