Analysis of coal mine safety production situation in China from 2019 to 2020

Abstract

In order to explore the characteristics and laws of coal mine safety accidents in a more in-depth and objective way, the number of coal mine accidents and deaths in 2019 and 2020 published by the State Administration of Coal Supervision and the Coal Mine Safety Network in China were statistically analyzed from different perspectives, and the situation of coal mine safety production in China was analyzed by means of pie chart, bar chart and broken line chart combined with the current domestic situation of China. The analysis shows that: on the whole, the number of coal mine accidents and deaths in China has been at a relatively low level; in terms of accident types, roof, transportation and gas accidents are the main accident types that affect coal mine safety production in China. In terms of spatial distribution, the number of coal mine accidents in China is generally more in the north than in the south. The differences of geological structure and production capacity in the north and the south lead to different causes of the high occurrence of coal mine accidents. In terms of time distribution, the number of accidents in February and March is relatively small, while the number of accidents in June, July and August is frequent and concentrated. From the point of view of the specific time period, downhole work shifts are more prone to accidents.
