Statistical analysis of coal mine accidents in China from 2005-2013
Abstract
Filing up and categorizing coal mine accidents during 2005-2013 within china by mathematical statistics. Focusing the aspects such as accident types, occurrence time, geographical distribution, and death rate per million tons, analyzing the characteristics of coal mine accidents, and as well as summarizing the coal mine accident potential regularity. And then, it can be proposed the technical prevention means and safety management measures to prevent and reduce coal mine accidents scientifically and effectively. According to the accident categories, it can be analyzed that the number of roof accident and death are the most and the average mortality of fire accident are the highest. According to the months, the curve of accident is in line with the curve of death toll and both show fluctuation. February is the lowest, which is closely related to low temperature. According to the 27 provincial units, death toll of Guizhou, Sichuan, Hunan, Shanxi, Chongqing coal mine accident is relatively more. China should strengthen the supervision of these places.References
