A new safety design method of anti-explosion-explosion-venting is presented through the analysis of anti-explosion design and explosion-venting design of the gas explosion experiment device.It can fit the requirements of the experiment device,and may reduce the cost of the device obviously while maintain the safety by using the method.

To analyze the laws of gas explosion accidents in our country coal mines,the paper selected the gas explosion accidents during 1950-2000 as samples,analyzed the time and space distribution,the first class hazard and the second class hazard traits of gas explosion accidents on the whole and different gas grades.It showed that gas explosion accidents not only had concentricity on the space-time and hazard characteristics,but also had different grades for different gas coal mines,and it explained the dissimilarity.

The gas is one of the most important factors which endanger the security of the mining production. Most of serious accidents are the gas explosion accidents in coal mine. By investigating the damage situations of the gas explosion accidents and the related material, finding out why these incidents happen is an important way to prevent or reduce the gas explosion accidents. Based on the occurred gas explosion accidents, the author use the FLUENT software to simulate the process of gas explosion and get the variation law of various air current parameters is obtained in gas explosion. The explosion causes and development course are discussed. Compared with the explosion parameters collected on scene of accident, it provides comprehensive scientific basis for the accident investigation. The conclusion is helpful to adopt suitable measures to prevent the gas explosion.

With the development of science and technology and the improvement of people's living standard, Natural gas has been widely applied to daily life. But the sharp increase in natural gas explosion accident. In this paper, Analysis of the effects of gas explosion on the structure, and the safety of the structure was evaluated. By detecting the damage phenomena of gas explosion in a civil building, use the characteristics and law of the gas explosion and finite element simulation analysis method.

Gas explosion is a kind of harm partial load by accident, it is the main cause continuity of the collapsed buildings. Based on the gas explosion of a frame structure damage detection, this paper analyzed the characteristics of gas explosion and put forward problems when building structure design as well as the prevention and control measures of gas explosion.

The reason of manhole explosion caused by flammable gas is analyzed with the practical situation in Hong Kong.The flammable gas enters into the confined space of the manhole through cracks and holes in the pipe connecting the manholes,and accumulates gradually until explosive gas forms.When ignition source is contacted,a manhole explosion even a series of manholes explosion are caused.The countermeasure of plugging the pipe connecting the manholes is proposed.

Gas accident can be devided into gas brust accident and gas explosion accident.Among them gas explosion caused the greatest number of casualties in one accident,and it is prone to heavy accident.So if gas explosion can be prevented effectively,coal mining accident will be get under control.In this paper,the conditions of gas explosion and its protective measures of gas explosion are discussed.
