摘要
通过理论分析,得出对沿空留巷围岩控制的基本原则、巷内支护技术和加强支护技术。应用FLAC3D数值模拟结合工程实践,通过对比分析,研究了加强支护对沿空留巷巷道围岩垂直应力及垂直位移的影响,得出了最佳巷内初始支护方案和加强支护方案。
Through the oretical analysis, draw on the gob control basic principle, lane supporting technology and strengthen support technolo- gy. The application of FLAC3D numerical simulation in combination with the engineering practice, through comparative analysis, research strengthening support for surrounding nwk of roadway along goaf vertical effects of stress and the vertical displacement, the optimum lane ini- tial supporting scheme and strengthen the supporting scheme.
