Production safety is concerned continuously in coalmine, especially the gas safety is a key issue in the working management of coal production. With the development of information technology, a large volume of data should collected from sensors deployed in coalmine. Therefore, it is necessary to forecast gas concentration or evaluate the gas safety in the key point, for example, the underground working...
In this paper the necessity to apply Internet of Things (Hereinafter referred to as IOT) in the coal industry is analyzed. The architecture of a new kind of IOT for coal mine and its main technical indicators are proposed based on sensor technology, combined with Industrial Ethernet, 3G/WIFI wireless networks, wireless sensor networks and other technologies.
Under the guide of green mining theory of coal resource and green logistics concept, green logistics is introduced into the green mining technology. Firstly this paper defines the concept and connotation of green mining logistics based on analysis of green mining technology and green logistics. Then gives the composition of green mining logistics according to coal flow and material flow underground...
Most of the coalmine accidents are caused by people's unsafe behavior. Based on the basic theory and research methods of behavioral science, this paper analyzed human factors and rules affecting unsafe behavior. On this basis, it proposed the wholly integrated coalmine safety culture construction methods, with strengthening safety awareness, correcting unsafe behavior and training security practices...
Air flow character and gas mathematical mode of heading laneway in coalmine is researched in detail to tackle with normal ventilation and gas discharging problem. Combining with ventilation requirements and safety regulation in coalmine, control strategy which aims at both safety and energy saving is established at length. Moreover, conventional double fuzzy control model is found to carry out two...
The coalmine gas hazard affected safety of China coalmine production most. As there were lots of complicated and uncertain factors during gas accidents emergency rescue and making decisions process, accurate decisions can not be drawn by mathematics models with present information monitored by the KJ series monitoring systems such as KJ90, so experiences of former questions were urgently required...
