Abstract

Coal is the most extensively used nonrenewable energy source worldwide. In Pakistan coal is mostly mined by underground mining methods under poor and unsafe working environment. In this study, accident records of underground coal mines of Cherat coal field were collected and analysis was carried out to understand the consequences, time of occurrence and causes of accidents. Besides, occupation of a victim, responsible party and effects on production were also considered in present study. The relationship between workers’ age and severity rate was examined using regression analysis. The main causes of accidents were the fall of the roof, mine gases, electrocution, oxygen deficiency and slip fall. At Cherat coalfield, for every two mines, there is one fatality and most of the accidents occur due to roof fall between 10:00 am to 12:00 noon. It is due to the stress of production efficiency. Moreover, there is a negligible impact of accidents on coal production at Cherat coalfield from 1994 to 2015. Keywords
巴基斯坦Cherat煤田地下开采事故分析
煤炭是世界上使用最广泛的不可再生能源。在巴基斯坦,煤矿大多采用地下开采方法开采,工作环境恶劣且不安全。本研究收集了Cherat煤田地下煤矿的事故记录,并进行了分析,了解事故的后果、发生时间和原因。此外,本研究还考虑了受害人的职业、责任方以及对生产的影响。采用回归分析对工人年龄与严重程度的关系进行检验。造成事故的主要原因是顶板塌方、矿井瓦斯、触电、缺氧和滑倒。在Cherat煤田,每两个煤矿就有一人死亡,大多数事故发生在上午10时至中午12时之间。这是由于生产效率的压力。此外,1994 - 2015年间,事故对Cherat煤田煤炭生产的影响可以忽略不计。关键字
