三维高密度电法在底板水探测中应用

针对目前采用二维高密度探测矿井底板水, 只能获得巷道底板的富水性特征, 而不能获得工作面内部的底板富水性情况的现状,研制出了通过在工作面周边铺设电缆,采集工作面底板三维数据体的设备及数据处理软件,并结合三维成像技术,实现了工作面底板富水性采前三维探测、三维数据体垂直及水平切割技术.结合新汶煤田协庄煤矿71504W工作面应用实例,介绍了三维高密度电法技术在底板水探测中的应用, 实现了对工作面底板富水性采前三维数据体的采集、采场底板含水性三维电阻率成像, 可方便地进行水平及垂直切片, 将工作面底板富水状态直观地表现出来,说明了该技术的实用性和有效性.

Application of three-dimensional high density resistivity to detection of floor water

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.
