基于FLAC^(3D)的综放沿空掘巷锚杆支护研究

Based on FLAC^(3D) of Study on Bolt Support in Fully Mechanized Caving Mining along Goaf

煤矿巷道支护关系着煤矿的安全生产,文章根据巷道实际的地应力条件,运用FLAC^(3D)对煤矿巷道进行了初步设计方案的模拟。根据模拟的结果,选取了合理的锚杆间距、排距,并通过支护后的两帮和顶底板移近量,验证了支护方案的安全可靠性,希望通过本文的研究,为我国综放沿空掘进巷道支护提供借鉴。

The coal mine roadway support is related to the safety production of the coal mine.According to the actual ground stress conditions of the roadway,the FLAC^3D is used to simulate the preliminary design scheme of the coal mine roadway.According to the simulation results,the reasonable spacing of the bolt row is selected,and the safety and reliability of the support scheme is verified by the two groups and the top and bottom plate after support.
