本文汇总了苏联和我国现场的观测资料,说明工作面巷道中矿压显现的周期性是客观存在,不决定于老顶的岩性,认为其力学根源在于工作面老顶的周期性折断。作者提出了力学模型加以分析,肯定了韦伯尔波动假说。
This paper summarizes the observation data of the Soviet Union and China. It shows that the periodicity of mine pressure in the roadway is an objective reality and does not depend on the lithology of the old roof. It is believed that the mechanical root cause is the periodic fracture of the roof of the working face. The author put forward the mechanics model to analyze and confirm the Weibull fluctuation hypothesis.
