Comprehensive analysis control effect of faults on the height of fractured water-conducting zone in longwall mining

In order to examine the height of a fractured water-conducting zone due to the presence of a fault, a typical working face in the Baodian Coal Mine which is located in the Yanzhou Coalfield of northeastern China is examined as a case study. Two subsurface conditions with and without a fault are considered. In this study, equations are developed to calculate the maximum span of the unsupported roof with and without the presence of a fault....
