为了探索研究各种地震前兆现象,我国地震工作者已开始对地下水化学成分在地震发生前的变化进行观测。利用爆破作实验,是企图发现地下水化学成份在冲击力的作用下的变化,为识别地震前兆提供一定的依据。 本文着重研究江西永平铜矿前后三次爆破所取得的大量水化学观测资料,探讨爆破时水化学效应的特征,并确认爆破膨胀冲击力是使氡及水化学组分发生变化的主导因素,而各观测井孔所处的地质、水文地质条件及地球化学环境的不同,又起了加强或削弱的控制作用。为合理地选择水化学观测井孔(泉),以及研究在力的作用下水化学组分的变化特征,提供了实验依据。
In order to explore a variety of earthquake precursors, Chinese seismologists have begun to observe the changes of groundwater chemical composition before the earthquake. Blasting experiment is an attempt to find the groundwater chemical composition under the impact of changes in the impact of earthquake precursors to provide some basis. This paper focuses on a large number of hydrochemical observations obtained before and after Yongping copper mine in Jiangxi Province to investigate the characteristics of water chemical effects during blasting and confirms that blasting expansion impact is the dominant factor that changes radon and water chemical composition, The different geological, hydrogeological and geochemical environments in which the boreholes are located also serve to strengthen or weaken the control. In order to rationally select the hydrochemical observation well (spring), and to study the variation characteristics of chemical composition of water under the action of force, the experimental evidence is provided.
