摘 要：本文在收集朱庄矿井田及工作面地质及水文地质资料基础上，分析了太灰和奥灰长观测孔水位观测数据及突水点与各含水层水的水质分析数据，并利用灰色关联度理论进行了水质关联度分析。结果表明，Ⅲ633工作面突水水源主要来自Ⅲ632工作面的老空水，其次为Ⅲ631和Ⅲ6213工作面老空水，其补给水源为6煤层顶底板砂岩裂隙水，并非来源于煤层底板的太灰和奥灰的岩溶裂隙水。

Abstract： On the basis of collecting geological and hydrogeological data of Zhuzhuang mine field and working surface， this paper analyzed the water level observation data of Taihui limestone and Ordovician limestone long observation holed and the water quality analysis data of the sudden water points and aquifer water， and made the correlation analysis of water quality by using the grey correlation theory. The results showed that the water source of water inrush in the III633 working face mainly came from the goaf water in the III632 working face， followed by the goaf water in the III631 and III6213 working face， the recharge water source was 6 coal seam top plate sandstone crack water， not from the coal seam bottom plate of Taiyuan limestone and Ordovician limestone karst fissure water.

礦井突水威胁着煤矿的安全生产，治理突水的重点在于准确判别突水来源，减少水害事故的发生。判别突水水源常采用水位水温法[1]、水化学分析法和基于数学理论的分析方法。宫凤强等运用距离判别法对突水水源进行识别[2]，胡友彪等使用灰色关联度法[3]，徐星等提出基于遗传BP神经网络模型法等[4]，均取得了较好的效果。本文针对朱庄矿Ⅲ633工作面突水特征，根据突水工作面附近长观孔观测数据和水常规离子，分析了水位动态变化和水化学特征，并采用灰色关联度法对突水水源进行了判别[5]，进一步提高判别的准确性，对矿井防治水方案设计及工作面的安全开采具有重要意义。

1 研究区概况

1.1 工作面地质条件

朱庄煤矿位于淮北市以东约9 km，含煤地层为石炭—二叠系上下石盒子组和山西组，主采煤层6煤位于下二叠统山西组，厚度为2.6～3.2 m，倾角为14°～23°，煤层结构简单。井田呈现为宽缓褶曲构造，褶曲右翼走向北北西—南南东，倾向南西西，岩层倾角为7°～25°，局部发育小断层。……
