Evolution trend and statistical analysis of coal mine water disaster accidents in China from 2008 to 2019

Abstract

In order to deeply explore the occurrence rules and characteristics of coal mine water disasters in China, reveal the evolution trend of accidents, update accident statistics and analysis, and ensure the timeliness of relevant research, the information about coal mine water disasters in China from 2008 to 2019 published by the State Coal Mine Safety Supervision Bureau, China Coal Mine Safety Network, and coal supervision bureaus of all provinces (autonomous regions and municipalities directly under the central government) were collected using the method of mathematical statistics, this paper analyzes the four dimensions of space, time, water inrush source and mine type. The results show that: Shanxi, Guizhou and Heilongjiang are the cluster areas of water disaster accidents; the frequent occurrence period of water disasters is from March to August every year, and the accidents are relatively concentrated in the periods of 3:00-5:00, 9:00-11:00, 16:00-18:00, 22:00-24:00 every day; old goaf (kiln) water is the main source of water inrush; the number of accidents and the change trend of death toll within the statistical years are divided. They are increasing before peak, decreasing after peak and decreasing gently after peak.
