中关铁矿地下矿山涌水情况研究

在地下矿山生产中,地下涌水量对于矿山安全至关重要,掌握涌水量的变化规律以及 影响因素,在后期开采过程中起至关重要的作用。以中关铁矿涌水量为研究对象,通过现场地质调 查以及区域水文地质数值模拟等研究方法,研究地表水位、水压以及矿山的地质结构对矿山涌水量 的影响。结果表明:在没有降雨等外来补充下,地下水位以及井下涌水量的变化会保持在相对平稳 的状态,并持续一段时间;所建立的帷幕改变了灰岩的富水性、透水性,较天然含水层很大程度上降 低了地下矿山的涌水量,为保证安全生产提供了强有力的支持。

Study on Water Gushing in Underground Mine of Zhongguan Iron Mine

In underground mine production,the underground water inflow is very important for mine safety,and to master the change law of water inflow and the influencing factors plays a vital role in the later mining process. Taking the water inflow of Zhongguan Iron Mine as the research object,the influence of sur⁃ face water level,water pressure and mine geological structure on mine water inflow is studied by field geo⁃ logical survey and regional hydrogeological numerical simulation. The results show that the changes of groundwater level and underground water inflow will be remained relatively stable and continued for a period of time without external supplement such as rainfall. The curtain has changed the water-rich and water-per⁃ meable properties of limestone,and reduced the water inflow of underground mines to a great extent com⁃ pared with natural aquifers,which provides strong support for ensuring safe production.
