煤矿水文地质调查研究

摘要

××煤矿是一座比较大型的煤矿，水文地质条件比较复杂。随着开采深度的增加,水害威胁越来越大，防治水害工作比较严峻。因此，开展××煤矿水文地质调查工作，提出××煤矿的水害防范对策，研究工作具有一定的理论意义和实际应用价值。

本论文的主要研究内容如下：1、在对××煤矿水文地质条件的分析，对××煤矿开采煤层、构造和地表积水进行了分析和总结。 2、在研究煤矿水害和突水危险了基于事故的煤矿水害危险性评价方法。 3、利用上述研究成果对××煤矿进行了危险性评价。

4、针对××煤矿的不同水害类型及危害程度提出了煤矿水害防治措施。

本课题的目的是通过调查煤矿所处的矿区位置、地质与水文地质条件和矿山开采现状，进一步研究查明区内矿床水文地质条件及其充水因素，查明矿井水害类型及对矿井安全生产的危害程度，确定矿井水文地质条件复杂程度，并进行矿井水文地质条件分区，为合理地开发利用有限的矿产资源，确保矿井安全生产，提供依据。方法是在野外踏勘、生产矿井测量、老窑调查及邻近矿井资料收集的基础上，对本矿山水文地质资料进行综合分析。

根据综合研究成果可知，××煤矿矿井水文地质条件复杂程度为中等偏复杂状态。关键词：××煤矿；水文地质；涌突水；水害防治

ABSTRACT

Yanjia coal mine is a large mine.Hydrogeological conditions are complex.With the mining depth increasing, flood threats growing, control of water disasters is fairly severe. Therefore, investigation in Yanjia hydrogeological coal mine, prevention methods in coal mine water disaster, these study have some theoretical significance and practical value.

Contents of this paper are as follows. Firstly, Yanjia mine hydrogeological conditions are analysised, and coal seam coal mining, construction, and surface water are analyzed and summarized. Secondly,studying of water hazard in coal mine water inrush based on accidents of coal mine water disaster is risks and risk assessment methods. Thirdly, Yanjia coal mine make use of the research results conducted a risk assessment. Fourthly,for different water disaster type and harm of Yanjia coal level of coal mine water disaster prevention and control measures.

Purpose is through investigation coal mine by department of mine location, and geological and hydrological geological conditions and mine mining status, further research identified district within deposit hydrological geological conditions and filling water factors, identified mine flood type and the on mine safety of against degree, determines mine hydrological geological conditions complex degree, and for mine hydrological geological conditions partition, for reasonable to utilization limited of mineral resources, ensure mine security production, provides pursuant to.Methods are made in field reconnaissance, mine surveying, old mine surveys and mine data collection in the neighbourhood on the basis of integrated analysis on mine hydrogeological information.

Based on a comprehensive research, Yanjia mine hydrogeological conditions are complexity, medium complexity.

Keywords: Yanjia coal mining; hydrological geology; water; water hazard control
