摘要
回撤通道位置能否合理的确定,决定着工作面能否正常的接替。安家岭二号井工矿B902综放工作面,就曾因回撤通道未能确定好而耽误了不少时间。文章通过UDEC数值模拟来分析研究合理的回撤通道位置。
The proper position of the withdrawal entry decides the succession of coal mining workface.Work on the fully mechanized caving face in Anjialing No.2 mining B902 has ever been delayed for the inappropriate position of the withdrawal entry.This paper will study and analyze the ideal position of the withdrawal entry by means of UDEC numerical simulation.
