介休井水位异常的调查与分析
|
摘要
从井孔周围地下水开采量变化、大气降雨补给量变化、农田灌溉用水量变化、矿井塌方、涌水、排水和地震活动等影响因素入手 ,对 1999年至 2 0 0 0年间介休井水位的 2次突降原因进行了调查。通过初步分析 ,表明介休井水位阶降型异常具有一定的震兆性质 ,其水位的缓慢上升与突然阶降意味着介休地区断裂活动在加速。其地震预测的意义是未来一段时间山西地震带内有发生MS≥ 5 0级地震可能
An investigation of the cause of twice abrupt descents of water level in Jiexiu Well during the period from 1999 to 2000 was made based on the following influential factors:①the variation of the exploitation quantity of groundwater.②the variation of supplementary quantity of rainfall.③the water consumption of farmland irrigation.④the gush,the drainage,the collapse of mine and the seismic activities.The preliminary results show that the anomalous descent of water level signifies a certain kind of character of earthquake precursor.The slow ascent and abrupt descent mean the acceleration of fault activities in Jiexiu region.Then,there exits a possibility of the earthquake(M S≥5.0)occurrence in Shanxi Province in a certain period in future.
