矿井涌水水源分析的多元矩阵模型及应用

Study on Multivariate Matrix Model and Application of Identifying Mine Water-gushing Sources

及时准确地识别矿井涌水水源是防治矿井水害的前提。选择Mg^(2+)、Ca^(2+)、Na^++K^+、HCO_3^-、SO_4^(2-)、Cl^-和TDS等常规水化学指标作为水源分析的判别因子,以新庄孜矿28组水样数据构建了水源识别的三元矩阵模型。为检验模型的可靠度,将其用于水文地质条件相近的许厂煤矿涌水水源的识别研究。

Identifying mine water-gushing sources accurately and quickly is the important condition of controlling mine water disasters. Hydrochemistry indexes： Mg^2＋, Ca^2＋, Na^＋ ＋K^＋, HCO^3-, S04^2-, C1^- and TDS were regarded as the evaluation indexes for identifying mine water-gushing sources. Then, ternary mixture model was established based on 28 groups of water sample data of Xinzhuangzi coal mine as the training sample. Furthermore, to test the model＇s reliability, it was used to identify the water- gushing sources of six groups of water samples in Xuchang coal mine under the similar hydrogeological conditions of Xinzhuangzi coal mine .
