注浆工作面底板突水危险性分析与评价

Risk Analysis and Evaluation of Water Inrush from Floor of Grouting Working Face

为了探究奥灰上段富水情况,通过收集工作面254个底板注浆钻孔信息,对钻孔水量、水压、水温等水文信息和底板导水性、钻孔注浆量等地质信息进行统计分析,对注浆工作面底板突水危险性进行评价,从而实现工作面安全回采,为评价注浆治理效果提供一种思路。

In order to explore the water-rich situation in the upper section of ordovician ash,by collecting the information of the 254 floor grouting boreholes in the working face,the hydrological information such as borehole water quantity,water pressure,water temperature and the geological information such as floor water conductivity and borehole grouting amount are statistically analyzed.The risk of water inrush from the floor of grouting working face is evaluated so as to realize safe mining of working face and provide a way to evaluate the effect of grouting treatment.
