摘要
竹山塘煤矿-170m水平掘进东八石门下山发生大的突水事件,涌水量高达1500m3/h,经过调查分析,找出突水原因是井区承压水沿断层构造薄弱带导入巷道,采取综合措施对突水进行治理之后取得较好效果。
A groundwater inrush with the amount reaching up to 1*!500m3/h occurred at the -170*!m level development of Dongbashimen tunnel in Zhushantang coal mine. Through investigation and analysis, it was discovered that the ground water inrush results from the confined water in mine gushing into the tunnel through weak fracture of fault tectonic. Good effect was obtained after the groundwater was controlled using comprehensive measures.
