The Remain Life Research of Ventilator System Based on Failure Data Analysis

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 with reliability theory, such as time homogeneous process etc.. The indexes we discessed are the key measuring index of markov repairable system. Finally a case study results showed the approaches we research on is significative and feasible.
