摘要
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.
Abstract
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.
