摘要
阐述了矿井直流电法及其在探测煤层底板突水中的应用．由于受全空间效应和巷道空间影响，井下稳恒电流场的分布有其特殊性．文中重点叙述了不同矿井直流电法的全空间效应和巷道影响特征，给出了拟一维层状介质模型的巷道影响校正系数公式．结合应用实例，对巷道底板电测深法、矿井电剖面法和高密度电阻率法资料的处理与解释方法分别进行了讨论．
DC electrical method and its application in detecting water burst from the seam floor of a coal mine is introduced. Being influenced by full space and drift space effect, the distribution of DC electric field in coal mine has its specific characteristic. The characteristics of influence of full space and drift space effect on DC electrical method used in different coal mine is emphatically described. A formula for correcting the pseudo 1D layer model which would be influenced by drift space effect is given. The electrical sounding method for determining the depth of drift floor, the electrical profiling method used in coal mine, the method for processing and interpreting the data obtained by high density resistivity method, as well as some applied examples are discussed.
