Study and prospect on coal mine composite dynamic disaster real-time prewarning platform

To overcome the difficulty in real-time forecasting and prewarning of coal mine composite dynamic disasters, the paper investigated on the occurrence mechanism of composite dynamic disasters and the relevance to prewarning signals,by dividing prewarning signals into universality and individuality prewarnings and corresponding them to moni- toring parameters,through which key monitoring parameters of real-time,mid-time and long-term prewarning are pro- posed. Real-time prewarning platform of composite dynamic disasters is mainly composed of monitoring hardware,anal- ysis software and prewarning methods. Monitoring hardware mainly includes dynamic disaster monitoring system and platform monitoring room facilities;and analysis software refers to a platform’ s data collection and analysis software; and prewarning methods include multiple methods like composite disaster joint warning methods and single parameter and multi-parameter joint warning methods. Based on the above studies,basic research and forecasting and prewarning research on coal mines in Henan,Shangdong and other provinces,where composite dynamic disasters may happen,are taken,and coal mines’ composite dynamic disasters are forecasted. Besides,the paper also forecasts the development tendency of real-time forecasting and prewarning platform of composite dynamic disasters.
