2000—2021年我国煤矿事故特征及发生规律研究

在统计2000—2021年我国煤矿安全生产事故的基础上，得出如下事故特征：2002年以后，我国煤矿事故起数和死亡人数分别以年均18.4%、17.6%快速下降|重特大、较大和一般事故起数占比总体稳定在1∶4：45，这表明要有效防范重特大事故，必须从化解一般事故做起|近五年顶板、运输、其他和瓦斯事故依然多发，瓦斯、顶板、水害、火灾事故易造成群死群伤|5月份事故多发，1月、11月、12月重特大事故多发|部分国有重点煤矿安全管理滑坡、乡镇煤矿违法违规仍是诱发群伤的主要原因。

Study on characteristics and occurrence law of coal mine accidents in China from 2020 to 2021

Based on the statistics of coal mine safety production accidents in China from 2000 to 2021, the following accident characteristics are obtained: ① after 2002, the number of coal mine accidents and deaths in China decreased rapidly with an average annual rate of 18.4% and 17.6% respectively. ② The proportion of major accidents, major accidents and ordinary accidents is generally stable at 1:4:45, which shows that to effectively prevent major accidents, we must start from resolving ordinary accidents. ③ In recent five years, roof, transportation, other and gas accidents are still frequent, and gas, roof, water and fire accidents are easy to cause mass casualties. ④ Accidents occurred frequently in May, and major accidents occurred frequently in January, November and December. ⑤ Landslides in safety management of some key state-owned coal mines and violations of laws and regulations in township coal mines are still the main causes of group injuries.
