A Dataset on Static Test using 7.5% and 15% of Hydrogen Peroxide for Acid Mine Drainage Prediction

This dataset results from a study that aims to evaluate the differences in using two concentrations of hydrogen peroxide in a static test for the generation of acid mine drainage (AMD) prediction. In Indonesia, static tests at the operational scale of mining companies, which aim to identify the potential for predicting AMD generation, are carried out using the net acid generating (NAG) test method. The test was carried out using 15% hydrogen peroxide, following the standards according to the ARD Test Handbook and the Indonesian National Standard (SNI). However, since 1990, PT Kaltim Prima Coal, Indonesia's largest coal mining company, has implemented a NAG test using 7.5% hydrogen peroxide. The study took 564 rock core samples from exploration activities at Bengalon and Sangatta Mine Sites. In addition, a study was also conducted on NAG Solution by analysing the metal concentrations of Fe, Mn, SO4, oxidation-reduction potential, conductivity, total dissolved solids, and temperature changes during the addition of hydrogen peroxide. This dataset can be used to understand the behavior of sulfide minerals contained in rock samples when hydrogen peroxide is added as a strong oxidizing agent. There are also static test results using the acid-base accounting (ABA) method on 20 pulverized rock core samples representing potentially acid-forming (PAF) and non-acid-forming (NAF) categories.

本数据集源自一项旨在评估静态试验中使用两种浓度过氧化氢对酸性矿山排水（AMD, Acid Mine Drainage）预测生成差异的研究。在印度尼西亚，矿业公司在作业尺度开展的、用于识别酸性矿山排水生成潜力预测的静态试验，目前均采用净产酸（NAG, Net Acid Generating）测试方法。此前，该测试严格遵循《酸性岩石排水测试手册》与印度尼西亚国家标准（SNI）的要求，使用15%浓度的过氧化氢进行。但自1990年起，印尼最大煤炭矿业企业卡尔蒂姆普里马煤炭公司（PT Kaltim Prima Coal）开始采用7.5%浓度的过氧化氢开展NAG测试。本研究从本加隆（Bengalon）与桑加塔（Sangatta）矿区的勘探活动中采集了564份岩芯样本。此外，研究团队还针对NAG溶液开展分析，检测了其中铁（Fe）、锰（Mn）、硫酸盐（SO4）的金属浓度，以及添加过氧化氢过程中的氧化还原电位、电导率、总溶解固体与温度变化情况。本数据集可用于解析作为强氧化剂的过氧化氢被添加至岩芯样本时，其中所含硫化矿物的反应行为。另有20份经粉碎的岩芯样本的酸碱会计（ABA, Acid-Base Accounting）法静态试验结果，这些样本分别被归类为潜在产酸（PAF, Potentially Acid-Forming）与非产酸（NAF, Non-Acid-Forming）类别。
