工作面平巷支护参数设计及数值模拟研究

Design and Numerical Simulation Study on the Support Parameters of Working Face Level Alley

为进一步提升软岩巷道的掘进效率和安全性,实现对软岩巷道的高效支护尤为重要。以某矿1121综采工作面为例在对其地质条件及其支护现状综合分析的基础上,采用锚杆动态信息法结合现场条件对锚杆、锚索以及顶网片的支护参数进行优化设计;基于FLAC3D软件对优化前后的支护效果进行对比,达到了预期效果。

In order to further improve the boring efficiency and safety of soft rock roadway,it is especially important to realise the efficient support of soft rock roadway.Taking 1121 comprehensive mining face as an example,based on the comprehensive analysis of its geological conditions and its support status quo,the support parameters of anchor rods,anchor cables and top mesh were optimised by using the dynamic information method of anchor rods and site conditions;the support effects before and after optimisation were compared based on FLAC3D software,and the expected results were achieved.
