Forecasting and Early Warning Technology of Roof Disaster in Coal Mining Face

Abstract

Based on the classic mine pressure theory and a large number of on-site data, in order to realize the forecast and early warning of the roof disaster at the working face, the joint analysis technology of the regional support and the self-correcting technology of the predicted waveform are proposed. Based on the analysis of the working state of the hydraulic support, this technology uses the computer's massive data rapid processing function to pass the pressure criterion and the periodical pressure during the production process., to analyze, reason, and modify the pressure criterion and periodic pressure in the production process, thereby predicting the periodic pressure waveform and finally completing the roof accurate analysis and prediction of movement laws, and alarms when dangers may occur, reducing the occurrence of roof disasters.
