摘　　要：龙永煤田栖霞灰岩岩溶水引起的突水灾害,成为直接威胁该区煤矿安全生产的主要因素。以白沙南矿区突水事故为例,在介绍白沙南矿区地质概况的基础上,阐述了该矿区3次突水情况及造成的危害,并对"10.20"突水事故的水源、水量、水质特征和突水通道等因素进行了全面的分析和研究。结果表明,该突水事故的水源主要是来自栖霞灰岩的岩溶裂隙承压水,突水通道主要为F0构造裂隙带及F5或Ft构造裂隙带。Water inrush disaster caused by Qixia limestone karst water in Longyong coalfield becomes a direct threat to the region as a major factor in coal mine safety production. Regarding the water inrush accident of the south of Baisha Mining Area as an example, on the basis of the introduction of the geological situation in the area, the article expounds three times water inrush conditions and hazards, and analyzes and researched water source, water quantity, water quality characteristics, water inrush channel and other factors of the ＂ 10.20＂ water inrush accident. The results show that the water inrush source is mainly from Qixia limestone fissure - karst confined water, and water inrush channel is mainly F0 tectonic fracture zone and F5 or F1 tectonic fracture zone.
