Abstract: In this paper,we based ours researches on the great deal of observation data on the hydrogeochemical effects,all of which were obtained from three surface explosions in the copper ore region of Yongping,Jianxi and two deep-well-explosions in Longhai,Fujian.It is believed that the explosive impulse force take an important role in various chemical changes in the components of Rn and other hydrochemistry.The effect of hy-drogeochemistry caused by explosions are necessarily associated with geological structures,hydrogeological conditions and geochemical environment in observation points.Based on this theory,the preseismic hydrogeochemical mechanism is discussed and studied.

摘要: 本文着重研究江西永平三次地表爆破与福建龙海两次井下爆破所获得的大量水文地球化学效应的观测资料。确认了爆破膨胀冲击力是使氡及其它水化学组份发生变化的主导因素;爆破后引起的水文地球化学效应与各观测点所处的地质、水文地质条件以及地球化学环境有关。在此基础上对地震的水文地球化学前兆机理进行了探讨。
