摘要
根据煤层冲击地压的非稳定性问题,建立了煤层冲击地压的力学模型,采用现代非线性科学的突变理论,对煤层变形失稳及冲击地压进行了突变理论分析,得出了煤层冲击地压发生的条件以及冲击地压发生时煤层变形的突跳量和所释放出来的能量表达式,其研究成果深化了对煤岩失稳和冲击地压发生机制的认识。
A mechanical model for rockburst was figured out to deal with the problems of instability of the roekburst existing in coal bed. he theory of modem nonlinear catastrophe is applied to analyze the deformation and failures of coal beds and the rockburst in them. The occurring conditions of rockburst in coal bed, the kick value of rockburst, and the expression of energy to release out when pressure pump happened. The conclusion of this research helps to improve the cognition of instability staying inside coal rocks and principle of occurrence of rockburst.
