Human error mining accidents

China s coal output in 2000 from 12.25 tons in 2012 increased to 36.5 tons, the annual coal output growth of 15.78%. But the coal output growth caused casualties occur frequently, the total coal production accounted for the world total 1/4, while the number of casualties is higher than the sum of the coal mine accident casualties other coal-producing country, the main reason is that human error. 

Work has its special properties in coal mine production line workers, the subject they are productive activity, and is the main excitation accident. Personnel errors has become an important source of danger of accidents, on the one hand, it lies in internal factors, such as age, physical, physiological, psychological, their safety awareness effect on the other hand it lies in the external factors of workers in the work, such as the environment, enterprises of staff supervision, the completeness of machinery and equipment effects of the above factors, induced to have accidents tend to internal factors, external factors, individual, forming a human behavior set beam. Therefore, prevention and reduction caused by human factors of accidents has become an important issue to be solved in coal mine enterprise. 

Coal mine accident human error model construction and team safety management mode analysis... 

ABSTRACT In recent years, coal mine accident happened frequently in our country. Based on the statistics about coal mine accident and accident mechanism analysis, the paper find out the main reason that lead to coal mine accident happened frequently in our country. Based on the existing accident model, it put forward coal mine accident human error model. And make detailed factor analysis and effective analysis for the model. Then, from the angle of team, the paper put forward team safety management mode for coal mine enterprises and the corresponding safety control measures. It is a new safe management thought for China s coal mine industry. 

For accident mechanism theory, many domestic and foreign scholars and experts have done much research and put forward a lot of typical accident theory. Such as Domino accident model theory proposed by Heinrich in 1936, Energy transfer accident theory proposed by Gibson in 1961, then derived by Haddon in 1966, Gold mine accident model proposed by Lawrence in 1974, and so on. In domestic, Chen Baozhi put forward the two class of hazard point in 1995, Zhang Li put forward Human error accident model in Complex man-machine system in 1996, He Xueqiu put forward... 

In summary, the accidents main reason is closely related to human behavior. From macro-viewpoint, if the behaviors of corporate decision-making layer, management layer, operate layer are correct if equipments, machines and tools can achieve inherent safety through the scientific and technical personnel research and safety technical personnel operate standard if environment conforms to safety standards, the accident would not have happened. So, coal mine accidents human error mechanism model is established, human error is the primary reason for coal mine incidents. 

COAL MINE ACCIDENT HUMAN ERROR MODEL... 

By reason analysis for coal mine accident Occurred in our country in recent years, relying on the error theory, based on the accident mechanism that predecessors had established (Li Zhicheng, et al. 2005), the paper constructed coal mine accidents human error model , as shown in Figure 1. 

That the theory coal mine accidents human error model proposed in the paper mainly reflects that human error is the ultimate reason lead to accident. The model contains two parts, that is, inside and out the red line region. Part of outside red line region embodies the relationship from the macroscopic among human error, object misconduct and environmental degradation, and the accident mechanism and consequences Part of inside red region describes the different accident processes from the microscopic. As shown in the model diagram, object misconduct and environmental degradation are... 

Based on the above analysis, the paper give a new definition for accidents category, that is. All coal mine accidents can be divided into 4 categories, that is, accident is directly caused by human error, we called it A class accident accident is caused by human error and object misconduct, we called it B class accident accident is caused by human error and environment degradation, we called it C class accident accident is caused by human error, object misconduct, environment degradation in the same time, we called it D class accident. So, we can say, human error is the ultimate reason of all accidents, and it is the essence of coal mine accident human error model. 

According to the coal mine accident human error model and coal mine accident main reason in our country, the paper raises the method to improve enterprise safety management level by constructing excellent team management mode, shown in Figure 2. 

From the perspective of the coal industry, through making analysis about many coal mine accidents, it established the coal mine accident human error model by observation and interpretation on the coal mine accidents mechanism from a new angle, and provided the reference for coal mine accident prevention business. 

The Importance of Human Error in Mining Accident Causation... 

Despite these provisions Simpson (1996a) pointed out that, within UK mining operations, no prosecution had been made against designers, manufacturers or suppliers in the 20-plus years since section 6 of the 1974 Act enabled such action. There can be no doubt that there were, during that period, accidents which were, in part at the very least, a result of designed-in human error (and thereby accident) potential. 

Considerable evidence has been presented to indicate the all-pervasive influence of human error on mine accident potential across a wide range of mining operations and locations. Equally, the examples quoted indicate clearly that, while there may be occasions where the person who made the error is culpable, in the vast rrrajority of cases the errors have been at least predisposed (arrd, on some occasions, directly caused) by errors rrtade elsewhere in the orgarrisation (or indeed in other... 

This book has been written primarily for the mining industry. Despite all the major improvements in mine safety (both surface and underground), it remains one of the most intrinsically hazardous occupations in the world. Moreover, in mining (as in other industries) human error in some form is almost certainly the most prevalent of accident causal factors. However, although there is considerable literature on mining human factors, the systematic assessment of human error potential, especially as a preventative measure, remains rare (as is equally the case in some other industrial settings). 

Although not primarily written for human factors specialists, there is within the text a considerable body of real examples of human error which has, or is likely to, predispose accidents and a number of techniques and approaches which are probably not widely known outside of the mining human factors fraternity. It...
