Study on Application of Mine Pressure Monitoring and Measuring and Data Information Fusion Technology in Mining Face

Abstract：Based on the roof control technology of the surrounding rocks in the coal mining face,the practical mine pressure theory and the analysis on the large amount of the mine pressure monitored and measured data information,a new method of the coordinate structure model was provided to reflect the roof stability parameters of the gateway surrounding rocks（the load and the displacement）.The overburden strata fransmission rock beam theory in the goaf was applied to analyze and discuss the pressure monitoring and measuring curves of the hydraulic powered support applied to divide the pressurized characterization type theoretical study and the basis method which could reflect the roof mechanical and physical performances.In combination with the roof pressurized and falling phenomenon,the paper had a discussion on the creep pressurized law of the roof movement and the abnormal pressurized condition occurred and the mechanics structure model of the powered support and roof was established.The paper had a further analysis and study on the roof normal pressure creep development law and on the division and formation causes of the falling area,abnormal pressure serous variation and catastrophic area.With the project applications as the examples,the paper had a detail analysis and summarization on the mechanics model and the building principle of the pressurized area affected to the engineering technology management and development.
