综采工作面区段煤柱合理宽度研究

Research of Reasonable Width of Coal pillars in Fully Mechanized Face

通过对西曲矿2#综采工作面区段煤柱合理宽度的留设理论分析,根据煤柱保持稳定的基本条件对工作面煤柱合理宽度进行了理论计算,应用FLAC3D软件对其进行了模拟计算。结果表明:理论计算结果与模拟结果相吻合,为类似区段煤柱合理留设提供依据。

Based on the theoretical analysis of reasonable width of coal pillar in No.2 fully mechanized mining face of Xiqu Coal Mine,theoretical calculation of reasonable width of coal pillar in working face is carried out according to the basic condition of coal pillar stability,and numerical calculation software FLAC3D was used to simulate and calculate it.The results show that the theoretical calculation results agree with the simulation results,which can improve the economic efficiency of the enterprise while increasing the coal mining rate.
