野外采样，室内测试。水样现场参数是在野外使用便携式多参数测试仪（Manta 2.0）进行原位测试，主要包括pH值、电导率（CON）和温度（T）。其他水化学指标的测试是在陕西省煤矿水害防治技术重点实验室进行的。其中，主要阴阳离子（Na+， K+， Ca2+， Mg2+， NO3-，SO42−，Cl-）采用离子色谱法测定，测试精度为1%。 HCO3 -和CO32-采用盐酸常规滴定法测定。总溶解固体（TDS）是通过计算得到。对于氢氧稳定同位素（δD和δ18O）的测定，选择按VSMOW标准采用液态水同位素分析仪（LGR LWIA-24d）测定，测试精度分别为0.21‰和0.04‰。氚同位素(3H)值由液体闪烁光谱仪(1220 Quantulus)电解浓度法测定。", "ds_quality": "

This dataset was collected through field water sample collection from the Dahaize and Balasu mining areas in Yulin City, Shaanxi Province, and tested in the laboratory. The dataset contains hydrochemical data from two study areas, the Dahaize mining area and the Balasu mining area. The main indicators include major eight ions, hydrogen and oxygen isotopes, tritium, soluble silica, pH, etc. There are a total of 39 sets of data.

Among them, the main cations and anions (Na+, K+, Ca2+, Mg2+, NO3-, SO42-, Cl-) were determined by ion chromatography with a testing accuracy of 1%. HCO3-and CO32-are determined by conventional titration with hydrochloric acid. Total dissolved solids (TDS) are calculated. For the determination of stable isotopes of hydrogen and oxygen (δD andδ18O), liquid water isotope analyzer (LGR LWIA-24d) was used according to VSMOW standard, with testing accuracies of 0.21 ‰ and 0.04 ‰, respectively.
