干河井田水文地质规律及涌水特点分析研究

干河矿井为新建矿井,井田煤层埋藏深,带压程度高,地质构造复杂.在建井过程中,通过开展水文地质钻探、地下水水位动态监测、矿井涌水量观测等水文地质基础工作,对矿井涌水与各含水层水位变化的关系进行了深入研究,分析了井田边界断层的导水性,各主要含水层的赋水性、各含水层之间的水力联系.基本查明了干河井田的水文地质规律,并得出了干河矿工作面涌水的原因及治理措施.

Analysis and Research on Hydrological Geology Rule and Water Burst Characteristic of Ganhe Field

Ganhe mine is new mine,the buried depth of coal seam in field is deep,the degree with water pressure is high,the geologic structure is complex.In the mine building process,through developing hydrology geology foundation work such as the hydrology geology drilling,the dynamic monitoring of phreatic water surface,the observation of water burst and so on,further research the relationship between water burst of the mine and water level change in each aquifer,analyzes the hydraulic conductivity of boundary fault...
