摘要
对于地质勘查钻探孔,除了岩芯取样、岩芯试验、水文试验之外,还可以利用钻探孔获取孔内破碎带、节理、溶洞、涌水点等特殊地质情况,孔内摄影及物探测井是一种有效的手段,在公路、铁路、水利、电力工程勘察等领域都有重要的应用。
For geological exploration drilling holes,in addition to core sampling,core test and hydrological test,we can also use the drilling hole to obtain the special geological conditions such as fracture zone,joint,karst hole and water gushing point.In hole photography and geophysical logging are an effective means,and it is widely used in highway,railway,water conservancy,electric power engineering investigation and other fields.
