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。 Timely and accurate identification of mine water gushing water is a prerequisite for prevention and control of mine water damage. The conventional water chemistry indicators such as Mg 2+, Ca 2+, Na +++, HCO 3+, SO 4 2-, Cl ~ - and TDS were selected as discriminant factors for water source analysis The ternary matrix model for water source identification was constructed based on 28 sets of water samples from Xinzhuangzi Mine. In order to test the reliability of the model, it is used to identify the water inflow of Xuchang coal mine with similar hydrogeological conditions.
