摘要
本文用光弹试验、梁理论和几何分析法等力学方法,分析了采场老顶初次来压时镶嵌块体结构的稳定性问题,给出了老顶初次来压的失稳判据。
By means of photoelastic experiment and geometrical analysis the paper discusses the structural stability of the main roof in form of inserted block beam during first weighting in longwall face. The criteria of failure of the main roof during first weighting have been presented.
