摘要
为解决复合顶板巷道维护难的问题,以车集煤矿2609区段运输平巷为例,研究了该巷道的地质条件,并通过FLAC数值模拟软件对巷道在原支护和各种新支护方案下的应力分布和变形特征进行模拟分析,最终确定巷道围岩控制的合理支护方案和科学支护参数,经工程实践表明,巷道围岩表面位移量和顶板离层量都比较小,维护了巷道稳定性,达到预期目标。
Aiming at the maintenance of composite roof roadway, based on the condition of 2609 section transport drift of Cheji Mine, the geological conditions were studied, the stress distribution and deformation characteristics of roadway was simulated under the original and new support schemes, and the reasonable support and support parameters for surrounding rock control were obtained. The practice showed the surface displacement of surrounding rock and roadway roof separation were well controlled, and the roadway stability was maintained.
