红沙泉一号露天煤矿勘探阶段使用大井法和平均降雨量法预测露天采场涌水量,与实测涌水量偏差较大。根据矿田水文地质条件,以及露天采场涌水量构成与变化规律,结合煤矿开采程度,进行偏差分析。结果表明,采用的年平均降雨量值为较大范围年平均降雨平均值,导致涌水量预测结果偏大,而选用水文地质比拟法预测未来3年采场涌水量,误差较小。预测结果为红沙泉一号露天煤矿防治水工作提供了重要参考依据,能够更好地指导安全生产。

itation method were used to predict the water inflow of the open-pit mining site, which deviated significantly from the meas-ured water inflow. We analyze the deviation based on the hydrogeological conditions of the mining field, the composition andvariation of the water inflow in the open-pit mining area, and the degree of coal mining. The results show if the annual aver-age precipitation including that of the nearby mountain is adopted, which is actually a large-ranged one, the predicted valueof the water inflow world be larger. The hydrogeological analogy method is used to predict the water inflow in the next threeyears, with relatively small errors. The predicted results provide an important reference for the water prevention and controlof the Hongshaquan No. 1 open-pit coal mine, and are of better guidance for safety production.
