摘要
针对王庄煤矿的抽采半径的影响因素进行测定和研究,通过分析提出理论和实测抽采半径,确定3号煤层抽采半径为1 m、钻孔间距设为2 m,保障王庄煤矿瓦斯治理有效进行。
Based on the measurement and research of the influencing factors of the drainage radius of Wangzhuang Coal Mine,the theoretical and measured drainage radius is proposed through analysis.The drainage radius of Coal Seam 3 is 1 m,and the borehole spacing is set to 2 m,thereby ensuring the effective gas control in Wangzhuang Coal Mine.
