摘要
采用综合实验室测试、数值模拟和现场实测等方法研究塔山矿特厚煤层沿底巷道顶板离层演化特征。结合3DEC软件模拟和现场实测结果得出,采动过程中超前工作面距离对回采巷道顶板影响:超前工作面160 m以内为采动影响区域;160 m以外为无采动影响区域。
Studies the evolution characteristics of the top plate along the bottom roadway in the thick coal seam of Tashan mine by means of laboratory test, numerical simulation and field measurement. The combined with the results of 3 DEC software simulation and field measurement, it is concluded that the influence of the distance of the working face on the roof of the mining roadway is the working area is within 160 m and the area is affected by 160 m.
