羊场湾煤矿一号井水文地质特征分析

Analysis on the hydrogeological conditions in Yangchangwan coal mine

随着回采深度的增加,宁东矿区羊场湾煤矿水文地质条件愈加复杂。通过对该矿导水裂隙带高度计算,分析了回采过程中主要的充水水源,由此对矿井充水量、涌水量进行了计算,最终综合确定了矿井水文地质类型为复杂型,为矿井开拓方式的选择和采掘系统的布置提供了科学依据。

With the increase of mining depth,the hydrogeological conditions of Yangchangwan coal mine in Ningdong mining area are more complicated. By calculating the height of water flowing fractured zone,analyzing the water filling sources in the process of mining and predicting the mine water inflow,it was determined that the mine hydrogeological type is complex. The result can provide scientific reference for the selection of development scheme and the arrangement of coal mining and tunneling system.
