Unsafe Behavior

Accident is undesired to anyone. But the research shows that the main cause of accident is unsafe behavior. The interaction mechanism of accident system was analyzed in the process of gas explosion through typical accidents and the conclusion was that the accident was occurred because unsafe behavior induced the dangerous factor in work environment. In order to further acquaint of it, the situation cognition of workers in the coal mine production process was analyzed with the research of aviation. The cognition of safe information in work process was affected by workload, goal, work habituation and others. As workload increased, goal strengthened, the attention apperceived safe information is weaken and the major change of safe information wasn’t apperceived immediately in work environment, and the accident was happened in conditions of unsafe behavior. Finally, the accident model based on situation cognition was posed and some measures were proposed.

The coal mine gas can cause gas explosion and gas outburst, which is a direct threat to the safety of coal mine production. The gas drainage technology is the highlights in the research of highly gassy mine and coal and gas outburst. Coal gas drainage in the coal mine area includes ground gas development and underground gas drainage. Therefore, the evaluation to the draining feasibility of the coal gas should also be divided into ground coal gas development and underground gas drainage. Draining feasibility of the gas refers to the draining extent in a certain area and the possibility of the development under existing economical situations. By general analysis to the geological parameter that influences the draining feasibility, the drainage area will be optimized in this paper. With the reservoir bed data analog technology, the draining feasibility of the coal gas in the DaFosi field and its draining protential will the evaluated in this paper.

Along with the rapid increase of energy consumption of China, more attention has been paid to the CBM as one kind of clean and high-quality energy. CBM is the greatest threat to the coal mining. If CBM is extracted and well used before coal mining, the environment will be improved and gas explosion accident in coal mine will be obviously diminished. The exploit and advantage of CBM improves the coal field exploration degree and coal mine production safety and efficiency.

End support on coal face is an important equipment of improving the work efficiency and the safety of coal mine production. Based on the work environment and the requirements for end support, the research analyzed the mechanical design of end support, such as its structure and composition. Moreover, several features which need to be paid attention to in the design of end support were proposed as well.

On February 4, 1970, in the Fouquières-lès-Lens coal mine in northern France, sixteen miners were killed in a gas explosion (“firedamp,” grisou in French). This was an accident like many others before it, yet with a relatively high number of fatalities. The public prosecutor concluded, as usual, that there was no case against the publicly owned mine. No investigation was to be carried out. The accident had been the work of fate, of bad luck.

The overall task of this paper is to elaborate a typology of the forms of labour that are needed for the production, circulation and use of digital media. First, we introduce a cultural-materialist perspective on theorising digital labour. Second, we discuss the relevance of Marx’s concept of the mode of production for the analysis of digital labour. Third, we introduce a typology of the dimensions of working conditions. Fourth, based on the preceding sections we present a digital labour analysis toolbox. Finally, we draw some conclusions. We engage with the question what labour is, how it differs from work, which basic dimensions it has and how these dimensions can be used for defining digital labour. We introduce the theoretical notion of the mode of production as analytical tool for conceptualizing digital labour. Modes of production are dialectical units of relations of production and productive forces. Relations of production are the basic social relations that shape the economy. Productive forces are a combination of labour power, objects and instruments of work in a work process, in which new products are created. We have a deeper look at dimensions of the work process and the conditions under which it takes place. We present a typology that identifies dimensions of working conditions. It is a general typology that can be used for the analysis of any production process.
