Coal mine accident and emergency rescue technology and equipment

The paper analyzed the number of various types of accidents, deaths and their ratios in Chinese coal mines from 2004 to 2015, and analyzed existing problems of coal mine accident emergency rescue technology and equipment. Occurrence of accidents mainly relies on manual discover, and emergency response time is long. Emergency communication and precision personnel positioning systems in underground coal mine are vulnerable to disaster, where disaster location and/or personnel position cannot be determined. Remote sensing range of disaster environment is small, the reliability is poor, and it is difficult to meet needs of disaster relief. Emergency scheme has poor pertinence and applicability. Emergency decision making is mainly depended on experience. Efficiency of manual demolition and support rescue equipment is low. Wind flow after disaster cannot be controlled real-timely and effectively, etc. It put forward emergency rescue technology of coal mine accident and key scientific and technical problems of equipment: ① determination method and technology of identification and spread range of serious accidents in coal mine; ② intelligent emergency scheme and rescue assistant decision making technology based on big data; ③ anti disaster emergency communication technology for coal mine; ④ precision personnel positioning technology in disaster (difficult); ⑤ intelligent control technology of wind flow after fire, gas and coal dust explosion disasters; ⑥ evacuation guidance technology for people in distress; ⑦ flying robot technology for monitoring disaster environment; ⑧ gas remote sensing technology in disaster environment; ⑨ rapid construction technology for rescue channel, etc.
