Abstract

With the rapid development of the gas industry, gas-run security issues are gradually emerging. Especially the gas gate well safety incidents have occurred. Due to the nature of the gas, accidents generally have serious consequences, affecting a wide range of characteristics, so, how effective prevention of accidents of gas gate well, the need to solve the problem. The gas gate well man - machine - environment system for the study, system analysis and research on the degree of security of the man - machine - environment system. To determine the impact of the gas gate well the risk factors analyzed accident statistics on the basis of in-depth study of the causes of the accident and the law, to identify the factors of man, machine and the environment, as well as management and other aspects of the accident; gas the gate well safety of the main factors; combined the actual situation of the gas, and to build gas gates wells system security evaluation index system, using AHP to determine each indicator weights. On the basis of the theory of mind in human behavior, identify the cause of the cause for the failures of the generation of people, and made the human security of the ways and means. The machines ergonomics analysis and reliability analysis, pointed out that the factors that affect the the gas gate wells machine security, as well as to reduce or eliminate the risk factors that should be taken measures and methods. On the environment in terms of analysis of the impact of the gas gate well air pollution, the operating environment, color and lighting, work space and other special environmental factors on the gas gate well system security, improve the gas gate well environmental safety measures and method. Security systems engineering principles of man - machine - environment system security foundation. Security systems engineering and theoretical basis from a dangerous source identification, risk assessment, risk control and other aspects of risk management. The traditional methods of risk control after the completion of the project, identification of the presence of dangerous source, evaluate their risk, strengthen management, and other means to control the risk, and then through the installation of additional safety facilities, the effect is largely restricted. This article by the study of accident prevention methods and gas the gate wells operating safety management principle to establish a the gas gate well safety evaluation of multi-level gray comprehensive evaluation model. Comparison of domestic and international gas standards, combined with the design standards of our gas, gas the gates wells system security evaluation to quantify the gray white of the safety factors. Abstract factors quantitative and comprehensive evaluation by calculating and comparing the security level of gas gate well. The use of experimental design methods and principles of the the selected indicators arrangements experiments to determine the interaction between the various indicators and indicators of the impact of the size of the overall goal, and put forward to improve the measures of the Gas the gate wells Security degree.
