The ventilation system conveys fresh air into laneway, dilutes the noxious gases, and keeps the working environment safe and reliable, how to evaluate the performance or reliability of ventilation system has been one of the important issues in coal mine safety research field. The reliability of underground coal face ventilation was discussed in this paper based on multi-sensor system data fusion approach...
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...
System reliability early warning aims to measure the rate of tolerance deviation from the reliability index borderline of the system running states, to confirm the early warning grade, and to assist decision-making warning. Analyzed and compared the methods of system early warning from home and abroad, and combined Rough Set (RS) theory and Artificial Neuron Network (ANN) technique, a new method based...
