Precursor of Thermal Power Disaster in High-Efficiency Intensifying Coal Mine and Its Early-Warning

Nowadays, the coal mine safety is still relatively vulnerable, especially with the frequent occurrence of mine thermal power disasters. Based on the characteristic of high-efficiency intensifying coal mine and the mechanism of thermal power disaster, the multi-factor coupling mechanism and process of mine thermal power disaster such as gas explosion and fire were analyzed. Meanwhile, the precursor characteristics of mine thermal power disaster and the precursor monitor and acquisition with no-blind area technology as well as such critical technology as precursor information treatment and early warning were also researched. These efforts above can help warn the serious thermal power disasters, operate the monitor equipment in advance and ensure effective warning time. All these have great significance in improving mine safety monitor and management.
