| titleOfInvention | Mine disaster prediction system |
| abstract | The utility model relates to a mine disaster prediction system, which comprises an AE sensor, an AE host and a data analysis host, wherein the AE sensor is arranged in a rock stratum between a roadway wall or a coal bed and a bottom plate roadway; a plurality of AE sensors are arranged at intervals along the extraction direction; the AE sensor is in communication connection with the AE host, and the AE host is connected with the data analysis host outside the well. The utility model discloses an installation AE sensor can gather the acoustic emission signal of back production in-process, and through analysis signal's response characteristic law, can catch the precursor information that back production in-process power phenomenon or calamity took place, through analysis power phenomenon or calamity acoustic emission evolution law around taking place, can synthesize the judgement early warning to the coal petrography gas power phenomenon or calamity of experimental working face. |
