水情监测预警系统在海下采煤中的应用

Application of flooding forecasting system to coal mining under sea

煤矿井下水情监测多用于对底板水的监测,而对顶板水的监测,以及对第四纪松散砂砾层水和海水溃入矿井的预警,目前尚未见报道。龙口矿业集团在海下采煤中,根据矿井水文地质条件,建立了以顶板含水层水位和矿井涌水水质为背景标志的水情监测预警系统。该系统可以在第四系水和海水溃入矿井前发出警报,以便及时采取应对措施。

Troditionally the coal mine water occurrence monitoring is applied to monitor the coal floor water outburst during coal mining. It is not reported that the monitoring system is used to forcast the roof water flooding or flooding caused by the incompact of Quaternary sand conglomerate aquafer and marine water. According to the hydro-geological condition of Longkou mining area the monitoring and forecasting system,which is base on the roof aquafer water level and water quality is established. The system can forecast the coal flooding before the Quatemary underground water or marine water breaks into the coal mine, resulting in the managing measures can be taken to get rid of the hazard.
