Long Progression and Cover Type on Cross-measure Cutting Coal Technology
Abstract：According to the stress analysis results in front of the the coal face about different location from coal seam during the process of cross-measure cutting coal by using FLAC numerical simulation software.The paper determined the range of stress concentration in front of drivage face,determined the different outburst prevention measures which should be taken.And then take the cross-measure cutting coal in Ⅲ1 Haizi coal mine as the background,this paper studied the cross-measure cutting coal technology.
