贵州小河口煤矿水文地质特征分析

Based on geological exploration data of Xiaohekou coalmine, combined with the regional hydrogeological characteristics, this paper explored the hydrogeological characteristics of the Minefield. The Result Indicates: Xiaohekou coalmine hydrogeological condition is medium close to simple, and the main aquifers are Mesozoic and Cenozoic Ida loose rock pore water and Mesozoic clastic bedrock fissure water. Groundwater recharge and spring mainly from atmospheric precipitation, runoff from the southwest to the northeast, eventually import the Wujiang River. The water-filled sources of the Minefield are surface water, groundwater, water of old coal mines and so on, and water-filled channel have broken joints cracks, mining caving zones and goaf fissures.
