摘要
针对郓城煤矿工作面带式输送机顺槽沿断层掘进时,地质结构复杂、富水性不清等问题,选取三维直流电法超前探测技术与WGMD-4高密度电法装置,辅以圆滑滤波因子建立数学模型,选用基于不等式约束的最小二乘反演方法,并对探测数据进行多次循环迭代处理,预测出地下赋存水的空间位置特征。
To the complex geological structure and the unclear water--abunoance in coal face crossheading drivaging along faults in Yuncheng coal mine,using ahead exploring water with three- dimensional DC resistivity technology and WGMD-4high density electrical system,inversion with least squares method based on inequality constraints,establishing mathematics model using detection data adopted loop iteration and sinooth filtration factor,predict the space position of underground water.
