Research On The Mechanism Of Electromagnetic Radiation And Its Application On The Rockburst Predict

Rockburst is a special pressure on the mines, as well as coal mine complex dynamic phenomenon, Mine is high-stress area of coal, rock and faults in an instant by the external disturbance instability damage, great release of energy caused by the outbreak of severe vibration, and the type of damage to the mine dynamic phenomena, Mine is a natural disaster. Serious threat to coal mine production safety. Entering the 1990s, China mine rockburst growing. As a result of China's coal mine rockburst disaster-hit countries.At present, China's main mining earthquake monitoring methods cuttings, acoustic emission, such as electromagnetic radiation. Drillings method though its simple easy line, But the drawback is that the forecast of time and space is not continuous, and the costs, time-consuming and can not meet the actual needs of the project .The AE method,because must contact the rock, the interference greatly. As compared with other methods of electromagnetic radiation can be achieved non-contact detection, With dynamic electromagnetic radiation disaster identification methods and technology and development to keep improving , it will display its tremendous scientific value and prospects This paper introduces theИЭМИ-1 electromagnetic radiation equipment and the principle of calibration method, coal rock electromagnetic radiation mechanism, Aggregate mining face abnormal stress grading and evaluation methods, as well as in August and September. October to December the actual test data records analysis, analysis of the 10 designated danger zone.Forecasting mine dynamic phenomena of recent trends, and with the support resistance associated roadway analysis of the measuring points of electromagnetic radiation intensity, and the analysis of face, Gate under the stress conditions. To further improve the electromagnetic radiation provided strong basis.
