含夹层岩体稳定性研究及其应用

The research and application of stability interlayer rock mass

依据层状岩体的结构及力学特性,将含夹层岩体视为一个完整的力学系统,建立了含夹层岩体组合系统力学模型。对含软(硬)夹层岩体的稳定性进行了分析,提出了相应的判别指标,为层状岩体结构的稳定性控制设计提供了依据。最后,介绍了该模型在含夹矸厚煤层综放开采岩层控制中的应用。

According to the contractual and mechanical characteristics of interlayer rock mass, regards it as a whole mechanical system, establishes a mechanical model of combined system of interlayer rock mass the stability of rock with soft (hard) interlayer is analyzed, relevant guideline of distinguish is proposed, a gist for control restraining designing of stability of interlayer rock mass. provided. At last, the paper introduces the application of the model in the control of integrated mining terrene with thick coal bed.
