Abstract

The invention relates to a drilling electrical prospecting device and method for an overburden water-conducting zone, and belongs to the technical field of prospecting. The drilling electrical prospecting device comprises a plurality of polyvinyl chloride plastic pipes and steel bars serving as electrodes, wherein a fixing hole is drilled in the middle of each polyvinyl chloride plastic pipe; the intervals between adjacent fixing holes are 2 meters; the steel bars are inserted into the fixing holes for fixing; electric wires arranged in the steel bars are taken as electrode cables; the electric wires pass through the polyvinyl chloride plastic pipes. The drilling electrical prospecting device and method for the overburden water-conducting zone disclosed by the invention have the advantages of total-space prospecting of the overburden water-conducting zone, wider prospecting range, higher prospecting accuracy and higher working efficiency. Necessary basic geological data is provided for hazard control, and a novel geophysical prospecting measure is provided for the prevention and control of coal mine flooding.

Description

technical field [0001] The invention relates to the field of detection technology, in particular to an electrical detection device and method for drilling water-conducting cracks in overlying rocks. Background technique [0002] At present, the data measured by the high-density resistivity method contain rich geological information, which can more accurately reflect the geoelectric conditions of the underground medium, and play an important role in the field of engineering investigation. However, the high-density resistivity method has been using traditional detection methods and devices in the detection of mine overburden water-conducting fracture zones. When detecting mine overburden water-conducting cracks, it can only detect a certain section of the rock mass, and the detection range is small. , low work efficiency. Contents of the invention [0003] The object of the present invention is to provide a drilling electrical detection device and method for water-conductin...
