Numerical Analysis of Spraying Hole Improving Permeability and Its Application in Outbursting Coal Seam

摘要：

Based on the coal and methane outbursting theory, we use FLAC3D to analyze the stress and strain distribution rules in coal body around the spraying holes. The simulating results are so appealing to help us to optimize spraying holes lay out in Qinan Coal Mines Face 713. The on-site drainaging records indicate the numerical results is reasonable and practical, and spraying holes laying is effective to improving the methane permeability.
