DYNAMIC MODEL FOR PREDICTING SUSTAINABLE WORK OF LONGWALLS

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.
