矿井钻孔测井分析仪在云冈矿上覆采空区积水探放中的应用

通过分析云冈矿12号层410盘区81010回采工作面上覆采空区情况,发现上覆3号层、7号层采空区中均存在积水,为消除该水患对回采工作的影响,须先行探放。文章结合81010回采工作面探放水实践,介绍了YCJ90/360矿用钻孔测井分析仪对钻孔轨迹的指导意义,以及测井技术对成孔准确性和可靠性的保障作用,证明其对采空区探放水钻孔施工具有必不可少的保障作用。

Application of Mine Borehole Logging Analyzer in Water Exploration and Drainage of Overlying Goaf in Yungang Coal Mine

By analyzing the situation of the overlying goaf of 81010 working face in 410 panel of the No.12 layer in Yungang Mine,it is found that there is water in the overlying goaf of the No.3 and the No.7 layers.In order to eliminate the influence of the water disaster on the mining work,it is necessary to explore and put in advance.Combined with the practice of water exploration and drainage in 81010 working face,this paper introduces the guiding significance of YCJ90/360 mine drilling and logging analyzer to the drilling track,and the guarantee function of logging technology to the accuracy and reliability of drilling,which proves that it has an essential guarantee function to the water exploration and drainage drilling construction in goaf.
