Abstract

Abstract:

As the coal mining depth and strength increase, rock-burst hazards has become increasingly serious. In recent years, rock-burst accidents happen frequently in the new mines, influence the safety production seriously. In the past two years, the mine has clearly entered deep mining, rock-burst hazards increased significantly and more and more serious. The paper monitors rock burst of 61051、41062 working face by electromagnetism radio technology, analyses the regular of electromagnetism radio, confirm forecasting critical value of electromagnetism radio by indistinct recognition method, knows rock burst premonition and electromagnetism radio of hazardous region, and forecasts rock burst time after time in hazardous region.

Key words: rock burst, thin coal seam, electromagnetism radio technology, regional prediction
