The Water Prediction and Control Engineering Project for Roadway through Badly Sealed Boreholes: –with Sijiazhuang coalmine of Yangquan Coal Administration as example

Badly sealed boreholes water inrush is one of big hidden dangers to coal production safety, this paper mainly studied water prediction and prevention engineering for roadway badly sealed boreholes in Yangquan Coal Administration of Yangquan Coal Administration, analyzed the range of the borehole deflection and delimitation of waterline, presented technical means and solution. The research provided a technical method for water prediction and control in similar projects.
