As a modern security design, Inherent Safety means that equipment and facilities is able to contain the inherent fundamental features to prevent accidents. Mine hoist is the most important equipment in the coal production. How to achieve safe, reliable, efficient production, has been the focus study at home and abroad. Inherent safety is reflected in hoist design, primarily through the design measures...
It is very important that to establish a rational and quantitative mathematical model for the safety management of coal enterprises. The model can help managers to develop practical safety management objectives. It can help people find out the safety production trends also. In this paper, time discrete state equation on the principle of Cybernetics was used to study coal mine safety production model...
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...
Contamination flashover directly affect the safety of coal production, by analyzing the pollution flashover mechanism is Characterization Equipment Leakage current drawn outer surface of insulation for insulation levels of representative physical quantities, the alarm value determined for the online monitoring system provides basis. External insulation design of substations and can find the online...
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...
