摘要
鲁15井水位对矿井崩塌过程有明显的反映。经初步分析表明,利用矿井大崩塌前的基些前兆现象可对较大矿井崩塌进行预报,如:大崩塌前小的崩塌活动次数加密;大崩塌前各活动期平均井水位变化、各活动期持续的时间和各平静期持续的时间都有变化;∑N-t和No-△t曲线都在大崩塌前28天出现异常。
Evident is the response of water level in the well Lu-15 to the process of mine collapse. Tentative analysis shows that using some precursory phenomena before a bigger mine collapse, a prediction of earthquake for the bigger mine collapse will can be made. For instance, the active time of less collapse before the bigger collapse will increase; the average change of water level in the well in each active period, the duration time ine ach active period and each calm period will all change before the bigger collapse: the abnormalities in the ∑N-t and No-△t curves will all appear 28 days before the bigger collapse.
