Application of Plank-shed Advance Support Technology in Driving through Very Soft Outburst Coal Seam in a Crosscut
GONG Xuanping
Abstract：No. 3 coal seam in Fuquan Mine is an extremely soft seam, rib spalling and roof fall frequently occurred in the process of driving through this seam in the crosscut, which even led to the gas overrun in return air and induced coal and gas outburst. For solving this problem, the site engineering geological survey and theoretical analysis were carried out, the failure mechanism and the main factors inducing outburst were made clear and a plank-shed advance support technology was proposed. Based on the site practice, the construction process design was completed and successfully applied in site construction, all of these can provided a technical reference for safely driving through outburst seam in the crosscut in coal mines with similar conditions.
