摘要
2013年4月山西东郭断层气氢浓度出现2次大幅度变化,按照异常核实工作方案,针对观测技术系统、集气系统、仪器标定、对比观测、周边环境开采情况等因素,逐一进行了分析。结果表明,氢浓度大幅度变化为非前兆异常,其主要原因是由周边新井钻孔施工,打井造成强烈振动干扰引起。
The gas hydrogen concentration appeared twice obvious changes on Apr.,2013 in Dongguo Fault in Shanxi.According to the working scheme of data anomaly,the factor was analyzed,such as the observation technology system,gas collection system,instrument calibration,comparative observation and mining groundwater in surrounding area,etc.The results revealed that the great variation of hydrogen anomaly was not a precursory anomaly,its main reason was that the intense vibration interference caused by the new drilling construction in the surrounding area.
