摘　　要：如何准确预测矿井涌水量,对煤矿的安全生产和经济效益影响重大。以巴彦淖井田矿井涌水量预测为例,分别采用解析法和数值法,对先期开采地段范围内2-1煤层的涌水量进行了预测。通过对预测结果分析比较,总结了两种方法各自的适用条件,并推荐采用数值法预测结果作为最终的矿井涌水量。实践表明,数值法在矿井涌水量预测中具有较高的精度。How to accurately forecast the mine water inflow has a great influence to the safe production and economic benefits of a coal mine. In this paper,the forecast of the mine water inflow in Bayannao Coal Field was taken as an example and the water inflow of 2- 1 coal seam in the scope of the initial mining district was forecasted by using the analytic method and numerical method respectively. Through the analysis and comparison of the forecast results,the applicable conditions for two methods were summarized,the forecast results of numerical method was recommended as the final mine water inflow. Practice showed that the numerical method had high accuracy in the forecast of the mine water inflow.
