摘要
余吾矿为高瓦斯矿井,由于N1202工作面两侧为采空区,导致N1202工作面以孤岛工作面的形式开采。本文结合N1202工作面地质条件概况,应用FLAC3D数值模拟软件分析研究了孤岛工作面和其回采准备巷道围岩应力和塑性区分布特征,确定了最优最安全的巷道布置形式,为类似条件的工作面安全高效采掘提出了一种新的思路。
YuWu coal mine is a high gas mine, due to both sides of N1202 working face is gob, resulting in the N1202 working face in the form of isolated mining face, combined with the geological condition of N1202 isolated working face , roadway surrounding rock stress and plastic zone distribution characteristics were analyzed by the application of FLAC3D numerical simulation software, the optimal roadway layout scheme is determined, which provided a new train of new thought for the similar condition safe and high efficiency mining.
