摘　　要：【目的】为探索井田太原组含水系统为独立的水文地质单元,地质构造控制和影响井田范围太原组岩溶裂隙水流系统的补、径、排条件。【方法】采用水化学特征及D、^(18)O稳定同位素含量测试分析方法,结合野外精细地质调查及井下涌水点观察。【结果】贾郭煤矿矿井突水水源来自王陶河河流补给,预测并通过钻孔验证,证实王陶河松散沉积物覆盖的太原组K2灰岩岩溶裂隙为突水水源的导水通道。受井田太原组岩溶裂隙水流系统的控制,王陶河河水通过河床下方的太原组K2灰岩含水层,顺层向井田凹陷构造的低洼处径流,导致主斜井K_(2)灰岩裂隙处引发突水。为贾郭煤矿矿井水害防治提供了可靠的依据,也为生产矿井井下突水水源识别提供了可鉴借的有效途径。【Purposes】By taking the water inrush event of Jiaguo Coal Mine as an example,the control effects of regional geological structure and mine field geological structure on the water-bearing system of Taiyuan Formation in coal mine are systematically studied.The water-bearing system of Taiyuan Formation in the mine field is regarded as an independent hydrogeological unit.Geological structure controls and affects of the supply,runoff and drain conditions of the karst fissure water flow system of Taiyuan Formation in the mine field are investigated.【Methods】This research has been carried out by using hydro-chemical characteristics and analysis of D,^(18)O stable isotope contents,combined with fine field geological survey and observation of underground water gushing point.【Findings】It is confirmed that the water inrush source of Jiaguo Coal Mine comes from the supply of Wangtao River.It is predicted and verified by drilling that the karst fissure of Taiyuan Formation K_(2) limestone covered by loose sediment of Wangtao River is the water conducting channel of water inrush source.Controlled by the karst fissure water flow system of Taiyuan Formation in the mine field,the Wangtao River flows through the K_(2) limestone aquifer of Taiyuan Formation under the riverbed,and flows along the layer to the low-lying structure of the mine field depression,resulting in water inrush at the K_(2) limestone karst fissure of the main inclined shaft.This work provides a reliable basis for the prevention and control of mine water disasters in Jiaguo Coal Mine,and also provides an effective way for the identification of water inrush sources in mines.
