摘　　要：通过利用矿井水文地质类型划分对地方小煤矿的水害隐蔽致灾因素进行了识别.对小煤矿的矿井水文地质类型划分与国有大中型煤矿进行对比分析,找出其划分的侧重点和不同点如老空水、地表水、矿井涌水量等内容;对之前得到的侧重点和不同点进行深入分析,根据其矿井水文地质类型划分的结果对地方小煤矿水害隐蔽致灾因素进行识别.得出了小煤矿水害隐蔽致灾因素有老空区积水情况、含水层富水特征、导水构造、采动效应引发或人为导水通道等.The paper identified the hidden causal factors of water disaster on the local small coal mines by the type of mine hydrogeological classification. Firstly, the type of mine hydrogeological classification and state-owned small coal mines were analyzed. Their focus and the different points of division were identified as the old empty water, surface water, and mine water inflow and so on. Secondly, the focus and the different points were mentioned in-depth analysis, and then according to their results by type of mine hydrogeological local small coal water disaster hidden causal factors were identified. Finally, covert causal factors of water disasters of local small coalmine were obtained, which are the situation of old goaf water, water-rich aquifer characteristics, hydraulic conductivity structure, mining or anthropogenic effects caused by lead and other water channels.
