复合岩梁是解决矿山顶板压力问题的力学模型,本文根据实验研究,探讨了复合岩梁的强度特性、变形特性及破坏特性。提出了复合岩梁具有应力似连续效应、变形边界效应、粘合状态的影响和层间摩擦力等特殊性质。上述研究的初步结果可为今后的现场矿压现象和支架类型的研究提供参考。
The composite rock beam is a mechanical model to solve the pressure problem in the mine roof. Based on the experimental research, this paper discusses the strength characteristics, deformation characteristics and failure characteristics of the composite rock beam. The composite rock beam is proposed to have special properties such as stress-like continuous effect, deformation boundary effect, adhesion state, and interlayer friction. The preliminary results of the above studies can provide reference for the future on-site mine pressure phenomenon and stent type research.
