有关氡气的来源、变化机制及共和地应力的关系尚处于研究过程中。本文将围绕这一问题对岩石标本进行压力试验和溶解试验,为氡预报地震的压溶机制提供实验依据。作者在对唐山地区水氡普查测定的基础上,采集井孔围岩及岩芯标本,开展岩石铀(钍)含量、岩石压氡、岩石水溶解氡及井孔水氡含量之间的综合研究。初步认为,当岩石受压变形破裂时井孔围岩中放射性元素的含量与氡逸出量呈正向关系。 The relationship between the source of radon, the mechanism of change and the republican stress is still under study. This article will focus on this issue on the rock specimen pressure test and dissolution test for the prediction of earthquakes radon pressure dissolution mechanism to provide an experimental basis. Based on the survey of water radon in Tangshan area, the author collected surrounding rock and core samples of boreholes, and conducted a comprehensive study on the contents of uranium (thorium), rock pressure radon, radon dissolved in water and radon content in borehole . It is preliminarily believed that the content of radioactive elements in rock mass surrounding the rock is in a positive relationship with the radon release when the rock is deformed under pressure and fractured.
