【摘要】 针对邱集煤矿在岩巷掘进过程中发生的重大突水事故,结合矿井地质和水文地质信息,利用三维地震数据动态解释技术和地震属性技术,确定了陷落柱的存在及其平面位置、发育高度、空间形态。结果表明,该陷落柱位于出水点东南280 m处,平面长轴长度约为200 m,短轴长度约为150 m,高度为50～80 m,空间形态类似于烟囱体和盐丘体。该结果可为矿井防治水害提供水文地质依据。更多还原

【Abstract】 Aimed at addressing a major water-inrush-accident occurring in the tunneling process of Qiuji coalmine,this paper describes the determination of the existence,plane position,development height,and space form of the collapse column,combined with the information of mine geology and hydrogeology and based on the dynamic interpretation methods of 3D seismic data and seismic attribute technique. The results show that the collapse column,located about 280 m to the southeast of the water-inrush -point and with an about 200 m major axis and an about 150 m minor axis and a 50～80 m height, has a space shape similar to a sulfur chimney or salt dom.These findings provide an important hydrological basis for preventing and treating the coalmine water disaster.更多还原
