摘要
以张家峁煤矿14206工作面运输顺槽为工程背景,对运输顺槽的变形、离层量以及锚杆受力进行监测,通过室内试验得出煤岩物理力学参数,运用理论分析、FLAC^(3D) 数值模拟和现场工业试验对锚杆支护参数进行优化。现场监测结果表明,优化后的锚杆支护方案较好地控制了顺槽变形。
Takes the 14206 working face of Zhangjiama0 coal mine as the engineering background, theparameters of the bolt support are optimized by theoretical analysis, numerical simulation of FLAC3Dandfield industrial test, based on the analysis of the physical and mechanical parameters and thetheoretical analysis of the coal rock. The results of field monitoring show that the optimized bolt supportscheme controls the deformation of the roadway.
