煤矿地震信息中富水特性的分析研究

煤矿开采一部分主要地质任务是探测采区内地质构造的分布及其含（导）水性,采区三维地震勘探主要用于探测地质构造,而电法勘探则用于构造含水性的探测。为了探求三维地震勘探探测含水构造的可能性,采取对地震资料进行波阻抗反演的方法来提取含水信息,并结合实际的地震资料反演成果与瞬变电磁探测成果在富水区进行对比分析,发现地震资料提取的富水特性信息与瞬变电磁法测得的富水区域基本一致。结果表明,地震勘探技术在探测地质构造方面精度比较高,构造含水与否也可通过钻孔测井资料的标定来提取波阻抗反演信息来确定,并且关于含水信息定性解释具有一定的可行性,为以后地震勘探技术的发展提供了新的方向。

Water-bearing Features Analytical Investigation in Mine Earthquake Information

one of coal mining main task is to detect geological mining area geological structure and the distribution of water （guide）, 3 D seismic exploration was mainly used for detection of geological structure, and electrical prospecting was used to construct the aquosity detection. In order to explore the possibility of three-dimensional seismic exploration water-bearing structure, the method of wave impedance inversion of seismic data to extract water information was adopted, and combined with the actual seismic data inversion results and transient electromagnetic exploration results in the watershed, by comparing and analyzing them, the extraction of seismic data of the water rich information characteristics and the water enrichment area of the transient electromagnetic method measured were basically identical. Results showed that the seismic exploration technology in the detection of geological structure in terms of accuracy was higher, constructing water or not can be extracted by ddUing logging data of calibration information to determine the wave impedance inversion, and qualitative explanation had certain feasibility for the water information, which provided a new direction and the development for seismic exploration technology.
