Abstract：
In the process of green and smart mine construction under the context of carbon neutrality, China\'s coal safety situation has been continuously improved in recent years. In order to recognize the development of coal production in China and prepare for future monitoring and prevention of safety incidents, this study mainly elaborated on the basic situation of coal resources and national mining accidents over the past five years (2017-2021), from four dimensions (accident level, type, region, and time), and then proposed the preventive measures based on accident statistical laws. The results show that the storage of coal resources has obvious geographic characteristics, mainly concentrated in the Midwest, with coal resources in Shanxi and Shaanxi accounting for about 49.4%. The proportion of coal consumption has dropped from 70.2% to 56% between 2011 and 2021, but still accounts for more than half of the all. Meanwhile, the accident-prone areas are positively correlated with the amount of coal production. Among different levels of coal mine accidents, general accidents had the highest number of accidents and deaths, with 692 accidents and 783 deaths, accounting for 87.6% and 54.64% respectively. The frequency of roof, gas, and transportation accidents is relatively high, and the number of single fatalities caused by gas accidents is the largest, about 4.18. In terms of geographical distribution of accidents, the safety situation in Shanxi Province is the most severe. From the time distribution of coal mine accidents, the accidents mainly occurred in July and August, and rarely occurred in February and December. Finally, the \"4 + 4\" safety management model is proposed, combining the statistical results with coal production in China. Based on the existing health and safety management systems, the managements are divided into four sub-categories, and more specific measures are suggested.
摘要：
在碳中和背景下的绿色智慧矿山建设过程中,近年来,我国煤炭安全形势不断改善。为了认清我国煤炭生产的发展状况,为今后安全事件的监测和预防做好准备,本研究主要阐述了近五年(2017-2021年)全国煤炭资源和矿难的基本情况,从四个维度(事故级别，type,区域,和时间),然后根据事故统计规律提出了预防措施。结果表明,煤炭资源储量具有明显的地理特征,主要集中在中西部,山西、陕西煤炭资源约占49.4%。从2011年到2021年，煤炭消费的比例从70.2%下降到56%，但仍占全部的一半以上。同时,事故多发地区与煤炭产量呈正相关。在不同级别的煤矿事故中，一般事故的事故和死亡人数最多，692起事故和783人死亡,分别占87.6%和54.64%。屋顶的频率，气体,交通事故相对较高，瓦斯事故造成的单次死亡人数最多，约4.18从事故的地域分布来看,山西省的安全形势最为严峻。从煤矿事故发生的时间分布来看,事故主要发生在7月和8月，很少发生在2月和12月。最后,提出了“4+4”安全管理模式，将统计结果与中国煤炭产量相结合。基于现有的健康安全管理体系,管理层分为四个子类别，并提出了更具体的措施。
