In this paper, in accordance with the composition and features of ventilation safety monitoring information fusion system in the coal mine, analyzes the necessity for multi-sensors management. Underground for complex structure, wide area of the monitoring, usually the monitoring process is divided into many small targets monitoring area, the monitoring area of the mine ventilation system security...
The Coal mine safety is the keystone of the industry safety in our country, in which area, ventilation system is the basis to control the hazards such as gas explosion. Ventilator system is an important part of ventilation system, which can be seen as cold standby system, also is markov repairable system. Here we discussed and calculated the reliability and remain life probability of ventilator system...
The ventilation system is the basis to control the hazards in coal mine laneway. High reliability ventilation system can continuously convey fresh air into laneway , dilute the noxious gas, reduce disaster and ensure the mining productivity safe and effective. As we know that, many noxious gases in the coal mine laneway are compossible and their flowing states are complicated. In order to acquire...
Well-balanced and suitable ventilation is the postulate to keep the health of underground worker and the safety of the production. We take air quantity of laneway as the research emphasis, considering the release of state regulations on coal mine, we figure out the optimum area of air quantity via building the optimization programming model, and realize an actual case study to interpret the process...
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 currently-used mine main fan switchover is to stop the working fan first and then to start standby fan, which makes underground ventilation interruption during switching, and it is liable to cause gas concentration exceeding limits in high gas mine and threaten mine production safety. Based on the thought of changing the fan on standby from cold standby to hot standby before switchover, a novel...
Ventilation interruption in high gas mine during main fan switchover in the way currently-used that working fan stops at first and standby fan starts later is liable to cause gas concentration exceeding limit. In the paper, a novel way to realize ventilation unceasing during main fan switchover is put forward, in which, contrary to the way currently-used, standby fan was required to be started before...
The character of gas moving and air flow in heading laneway of underground coal mine were researched, control strategy which aims at both safety and energy saving was established at length. Moreover, conventional double fuzzy control model was found to carry out two work mode, normal ventilation and gas discharging. Since four input signals affect output in different degree, the idea of flexible weight...
Mine work face gas emission is the important basis for mine design, and has important practical significance for ventilation and safety production. Between mine gas emission and work face there are complex nonlinear relationships. The paper constructed a work face gas emission prediction model based on wavelet neural network. It based on statistics of a mine work face gas emission data, applied the...
The broad masses of coal mining enterprises have been very concerned about how to effectively evaluate safety and reliability of mine ventilation system. Domestic and international scholars in this regard have also carried out a substantial amount of research and made a variety of different types of evaluation methods, but because there are many complex factors that affect the safety and reliability...
At the present stage of development of Kuzbass coal-mining industry the tasks of coal production increase and coal-mining safety increase are of top priority. Use of polymer materials is one of the directions of efficiency and safety increase of coal-mining works. The positive experience of polymer materials use at the coal-mines of Kuzbass proved the importance of polymer technologies in solution...
