利用浓缩因子区划矿井富水性

Concentrated factors applied to identify mine rich in water

电阻率浓缩因子是相邻多个极距视电阻率之和与其中最小值之比 ,是在电阻率差异较小 ,无法解释时的一种数据处理方法 ,该方法突出有用异常、压制干扰性能较强。论文以郭二庄煤矿下架煤层涌水为例 ,研究了浓缩因子的求取方法和分区原则 ,利用浓缩因子将其底部奥陶系地下水富水性划分为三个区 ,并论证其划分的可靠性。

The concentrated factors of electric resistance rate are the ratio between the sum of several polar distance regarded resistance rates and the minimum.This method is a data processing method when the resistances have a small difference and are difficult to explain.The method has a high capacity of uneven and controlled interference.Taking the water inrush in Xiajia Seam of Guo 'erzhuang Mine as example,the paper studied the picking up method and area divided principle with concentrated factors.With the concentrated factors,three areas were divided according to the rich underground water in Ordovician system under the seam. The paper identified the reliability of the area divided.
