Study on Reasonable Staggered Distance of Simultaneous Mining in Close Distance Coal Seams
CAO Jian
Abstract：The reasonable staggered distance of the two face is the focus of security mining and optimal design in close distance coal seams simultaneous mining.Based on the theoretical calculation of voltage area and de-pressor area.The reasonable staggered distance between coal seam 2# and 3# +4# is 39.2 m ~44.2 m and 16.2m~34.2m in Shaqu, and depressor area theory has better feasibility.then through the application of nu-merical simulation sorftware, the best staggered distance is 16.2m., and it verify the analysis.The results of the research can provide some theoretical direction for making sure the reasonable staggered distance in the mining, and it also has significant meaning for mining under the simaliar condition.
