煤田测井中除专门水文地质钻孔外,一般钻孔并不进行扩散法、流量测井等专门的水文物探测井工作。因此,这类钻孔中遇到厚层石灰岩时,多用视电阻率方法确定其岩溶裂隙发育情况。但是仅仅靠这单一方法无法确定地层中发育的是溶洞还是裂隙,也无法确定岩溶裂隙中是否充填了泥质物,当然更不能在未进行水文物探测井的钻孔中对岩溶裂隙的含水性进
In addition to specialized geological drilling in coalfield logging, general drilling does not work on special hydrological exploration wells such as diffusion method and flow logging. Therefore, when encountering thick limestone in such boreholes, the visual resistivity method is mostly used to determine the development of karst fissures. However, it is not possible to determine whether karst holes or fissures are developed in the strata simply by this single method. It is also not possible to determine whether karst fissures are filled with mud material or not, of course, for the water-bearing properties of karst fissures Enter
