矿震及其深井水位的异常响应

MINING EARTHQUAKES AND ANOMALOUS RESPONSE OF GROUNDWATER LEVEL IN DEEP WELL

简要介绍了山东省陶庄煤矿的二次矿震及其并水位的同震效应与震前异常。结果表明，矿震活动与天然地震活动在时间上有同步性，并且二次矿震的井水位同震效应形态与震前异常持续时间有差异，而这种差异主要同震源体的破坏特征有关。

In this paper, two mining earthquakes and anomalous response of water level in adeep well before the earthquakes and during the earthquake's occurrence in a coalmine, Shandong province are presented. Based on the research results, the authors ad-vanced that there is a temporal synchronism between the mining and naturalearthquakes, and there are some differences between the precursory lasting time beforethe earthquakes and the curve form of water level during the earthquakeoccurrence. These differences are related to the fracture characteristics of the focal re-gion.
