Research status and development trend of mine electrical prospecting

  • 摘要: 隐蔽地质因素透明化是煤炭智能精准开采和煤矿重大事故防治的关键。煤岩体结构和流体赋存等因素变化均可引起显著的电性变化,奠定了矿井电法勘探的物性基础。30多年来矿井电法勘探在我国煤矿防治水中发挥了关键作用,经过采煤工作面顶底板探测、掘进工作面超前探测、采煤工作面内小构造探测以及矿井电法动态监测几个阶段的发展,产生了一大批标志性的理论、技术与应用成果,并在超前探测理论、方法、技术研究方面均居于国际领先水平。在归纳1980年初以来我国煤炭生产面临的主要水文地质问题的基础上,系统总结了在煤矿生产安全突出问题所处的不同阶段矿井电法勘探技术的发展历程和国内相关单位所做出的重要贡献,聚焦矿井电法勘探研究与应用现状,着重从多源信息融合、工作面透明化与矿井智慧化角度出发分析了矿井电法勘探的发展趋势。认为在实现煤炭智能化精准开采、深地探测以及地下空间开发利用过程中,矿井电法动态监测将成为电法勘探的未来发展方向,矿井电法勘探的应用领域将得到大幅度延伸,其发展前景也会更为广阔。

     

    Abstract: Transparency of hidden geological factors is critical to intelligent and precise coal mining and therefore the prevention and control of major accidents in coal mine. The significant electrical property change can be resulted from several factors, such as the structure of coal and rock mass, the fluid occurrence, etc., providing a basis of physical property for mine electrical prospecting. For more than 30 years, mine electrical prospecting has played a key role to water prevention and control of coal mine in China. Definitely, many symbolized results on theory, technique and application of mine electrical prospecting have been produced through several stages of development, such as roof and floor detection in coal face, advanced detection in driving face, small structure detection in coal face and dynamic monitoring of mine electrical prospecting. Meanwhile, studies on theories, methods and techniques reaches the international leading level. In this study, the main hydrogeological problems faced by coal mining in China since 1980s are summarized. On this basis, systematic conclusion is made for the development course of the mine electrical prospecting in different stages of prominent safety problems in the production of coal mine, as well as the significant contribution made by the related domestic units. Focusing on the research and application status of mine electrical prospecting, its development trend is also analyzed in view of multi-source information fusion, transparent working face and intelligent mine. Thus, it is considered that dynamic monitoring will become the future developing direction of mine electrical prospecting in the process of intelligent and precise coal mining, deep earth exploration and the development and utilization of underground space. Thus, mine electrical prospecting will have an expanded application field and wide development prospects.
