福建马坑铁矿主要含水层水化学特征与突水水源的识别

Recognition of Hydrochemical Characteristics and Water Source in Makeng Iron Mine,Fujian Province

本文对马坑铁矿主要含水层的水化学特征进行了分析,以灰色系统理论为基础,利用灰色关联度法建立矿坑突水水源的因素序列,对一次突水点建立参考序列,从而判定突水可能来自的含水层,并计算出各个含水层对突水量贡献的大小,为识别矿井突水水源提供了科学依据。

The hydrochemical characteristics of major aquifers in Makeng iron mine is analyzed in this paper. And on the basis of grey relation degree theory, a reference sequence of water inrush point and factors sequences of these aquifers are established to identify which aquifer water comes from. Moreover, water irruption quantity which comes from different aquifers can be calculated. This method provides a scientific basis for identifying the source of water inrush in mines.
