中文摘要：

根据新庄孜煤矿63301工作面的地质及水文地质条件,结合工作面突水的特征,并通过灰岩观测孔水位和水压变化的观测、水质常规检测等方法确定了工作面的突水水源和突水通道,揭示了工作面突水水源主要为C3-Ⅲ组含水层、奥灰含水层,其次为C3-Ⅰ组含水层和寒灰含水层,突水通道为工作面底板裂隙。分析结果为灰岩水的防治和A组煤的重新开采提供依据。

英文摘要：

According to the geological and hydrogeological conditions of 63301working face in Xinzhuangzi coal mine,combined with the characteristics of water-inrush,the observation of the water pressure and water level of the limestone observation holes, and detection of water conventional quality,we found that the major water-inrush sources were C3-Ⅲ group aquifer and the Ordovician limestone aquife,and the secondary sources were C3-Ⅰgroup aquifer and the Cambrian limestone aquifer.The waterinrush channel was the working face＇s floor cracks.The results can provide the basis for the limestone water prevention and to remining for the＂A＂group of coal.
