云泉煤业各水源类型的水化学特征分析研究
|
摘要
云泉煤业的主要水害类型为采空区水、顶板裂隙水,其次为地表水、奥灰水。为更快速高效地辨别出水水源,特针对性的采集了不同水源的水样,采用KSF-W300型矿井水源快速识别系统进行水样的甄别,遴选出具有代表性的水源水样,综合描述性统计、相关性分析、运用Piper三线图进而对不同水源的水化学特征及其形成机理进行了分析和探讨。结果表明:该矿地下水化学特征的形成主要受到岩石风化溶解作用的影响,同时伴随着一定的吸附交换作用及脱碳酸作用。其4种水源的水化学类型各不相同,地表水水化学类型为HCO_3-Ca,裂隙水的化学类型为HCO_3-Na,老空水的化学类型为HCO_3(SO_4)-CaMg,奥灰水的化学类型为SO_4HCO_3-CaMg。同时,总结出了4种水源类型的特征离子,并给出了特征离子的量化指标,便于后续日常探水及突水时更加快速高效地辨别出水水源,使得防治水作业更具靶向性。
The main types of water hazards in Yunquan Coal Industry Company are goaf water and roof fissure water,followed by surface water and Ordovician limestone water.In order to identify water sources more quickly and efficiently,water samples from different sources were collected.The KSF-W300 mine water source rapid identification system was used to screen water samples,select representative water samples.The hydrochemical characteristics and formation mechanism of different water sources were analyzed and discussed by descriptive statistics,correlation analysis and Piper three-line chart.The results showed that the formation of chemical characteristics of groundwater in this mine was mainly influenced by weathering and dissolution of rocks,accompanied by adsorption and exchange and decarbonization.The hydrochemical types of the four water sources were different.Surface water hydrochemical type was HCO_3-Ca,and fissure water chemical type was HCO_3-Na,and old empty water chemical type was HCO_3(SO_4)-CaMg,and Ordovician limestone chemical type was SO_4HCO_3-CaMg.At the same time,the characteristic ions of four types of water sources were summarized,and the quantitative indicators of characteristic ions were summarized.It was convenient to identify water sources more quickly and efficiently in the following day-to-day water exploration and inrush,which made the water prevention and control operation more targeted.
