摘要
充填体参数选择及优化是大采高沿空留巷巷旁充填支护技术成败的关键。以斜沟煤矿18505工作面下方材料巷为工程背景,通过选择4种充填体方案,研究其留巷充填体不同力学性能条件下的应力、变形以及对沿空留设巷道的维护效果,并且确定最优参数。
Success or Filling body parameter selection and optimization is the key to the supporting technology failure for the the thick coal seam with large mining height along the empty left lane. As 18505 face below material lane in 8# coal seam as engineering background,by selecting four filling schemes, to discuss the filling body for different mechanical performance under the condition of stress, deformation and along this empty roadway maintenance effect,and determine the optimal parameters.
