摘　　要：在矿井生产与建设中,矿井涌水量是一项十分重要的影响因素,是矿井建设防排水系统以及制定防治水措施的重要依据;因涌水量的影响因素相对较多,并且影响涌水量大小的原因较为复杂多变,故根据矿井实际情况,选择合理的涌水量计算方法十分重要。本次研究以榆树田煤矿涌水量预测为例,在分析总结榆树田煤矿水文地质条件的基础上,分别采用水文地质比拟法及大井法,对榆树田煤矿向斜北翼与南翼涌水量进行预测,为后续矿井开采提供理论依据。通过对比分析预测结果认为:比拟法较大井法预测结果更为准确;固定数值预测动态变化的涌水量存在一定误差,建议对矿井涌水量进行长期动态监测,及时修正或预测更接近实际的矿井涌水量。In the production and construction of the mine,the mine water inflow is a very important influencing factor,which is an important basis for the construction of the mine drainage system and the formulation of water control measures.However,there are relatively many influencing factors of water inflow,and the reasons for affecting the size of water inflow are more complex and changeable.Therefore,according to the actual situation of the mine,it is very important to select a reasonable calculation method of water inflow.This study took the prediction of water inflow in Yushutian Coal Mine as an example.Based on the analysis and summary of the hydrogeological conditions of Yushutian Coal Mine,the hydrogeological analogy method and the virtual large diameter well method were used to predict the water inflow in the north and south wings of Yushutian Coal Mine,which provided a theoretical basis for subsequent mine mining.Through comparative analysis of the prediction results,it is considered that the prediction results of the analogy method are more accurate than the virtual large diameter well method.There is a certain error in the dynamic change of water inflow predicted by fixed value.It is suggested that long-term dynamic monitoring of mine water inflow should be carried out to correct or predict the mine water inflow closer to the actual mine water inflow in time.
