工作面底板三维电阻率成像技术在杨村煤矿的应用

Application of the 3D-Resistivity Tomography Technique in the Hydrogeological Exploratory of the Coal Seam Floor Aquifers in Yangcun Coal Mine

杨村煤矿2704工作面为一受底板水威胁的采煤工作面,将三维电成像技术应用在工作面底板含水层水文地质条件探查,取得了良好的效果。探查结果表明,工作面底板十四灰含水层存在近SN(西部)和NE向(东部)两个富水带;奥灰含水层在工作面中东部存在一条不规则状富水带。

The 2704 working face in Yangcun Cole Mineissuch a coalface that is threatened by thewater in the seam floor so it＇s favorable to supply3D-Resistivity tomography to the ascertainment of the hydrngeelogical condition of the aquifers under the coal seam. ＂lhe exploratory result shows that two water - rich belts tending towords to NE in the fourteenth limestone aquifer in the seam floor and a irregular - shaped water - rich belt lies in the Ordovician limestone aquifer in the central - eastem part of the working face.
