小屯煤矿无机和有机水化学特征及水源判别研究

为了准确判别小屯煤矿井下突水水源，在小屯矿区开展了无机和有机水化学特征研究。结果表明，研究区内玉龙山灰岩水、长兴灰岩水与第四系水或地表水存在密切水力联系，夜郎组玉龙山段含水层与长兴灰岩含水层之间水力联系密切；大气降水与玉龙山灰岩水联系密切，采空区水与地表、地下水区别较大；大气降水直接补给长兴组灰岩含水层，经含水层涌入矿井，可以根据突水中DOM特征，判别采空区水突水水源。

Study on chemical characteristics of inorganic and organic water and water source discrimination in Xiaotun Coal Mine

In order to accurately identify the source of underground water inrush in Xiaotun Coal Mine，the chemical characteristics of inorganic and organic water were studied in Xiaotun mining area.The results showed that:there was a close hydraulic relationship between Yulongshan limestone water，Changxing limestone water and Quaternary water or surface water in the study area，and there was a close hydraulic relationship between the aquifer of Yelang Formation Yulongshan limestone water and Changxing limestone aquifer.The atmospheric precipitation was closely related to the Yulongshan limestone water，and the difference between the water in the goaf and the surface and groundwater was large，and the atmospheric precipitation was directly supplied to Changxing Formation limestone aquifer.The group of limestone aquifers，which were poured into the mine through the aquifer，could determined the possibility of water inrush from the goaf according to the DOM characteristics of the water inrush.
