Application of three-dimensional high density resistivity to detection of floor water
三维高密度电法在底板水探测中应用

At present with two-dimensional high density resistivity technique, only alley floor water-bearing characteristics can be detected, but working face floor water-bearing condition can not be obtained.With developmont of the laying cables surrounding the working face, the working face floor collecting three-dimensional data-data-processing equipment and software, combined with three-dimensional imaging technology, the three-dimensional data body vertical and level cutting technology is achieved for the floor water-rich exploration before mining coal layer.The three-dimensional high density resistivity chromatography imaging method, data collection and treatment process are introduced. With the example of 71504w working face in the Xiezhuang coal mine of the Xinwen coal field, technique, application of three-dimensional high density resistivity technique to detecting floor water, and the three-dimensional data body collection about working face floor water-bearing characteristic are presented and the three-dimensional resistivity imaging of the working face floor water-bearing characteristic is achieved. It shows that working face floor water-bearing characteristics can be displayed in level section and vertical section, and the practicality and validity of this technique are proved.
