Abstract
The analysis and phase portraits of the extraction process from longwall at different stages of time have been made. It is determined that the transition from a stable mode of work to an unstable one occurs gradually. The steady mode of coal mining from a longwall in the form of self-oscillations with the period of 6−12 days is proved, wherein the variation of excovation oscillations does not exceed 30%. A technique has been developed that allows for the early stages to determine the instability of the dynamic system.
