Thirty-four deceased who were killed from twenty cases of coal-mine accidents during fourteen years from 1965 to 1978 were autopsied in our laboratory and their causes of death have been discussed. In the explosion of methane gas and coal dust chemical energy stored in coal or methane is converted to mechanical energy and thermal energy which act upon the human bodies to bring about seven sorts of causes of death. Deaths are caused more frequently by thermal energy directly or indirectly than by mechanical energy. It is a characteristic found in the explosions of coal mines which are large and closed underground spaces consisting of inflammable material. In gas spurt major cause of death is asphyxia from the lack of oxygen resulting from the substitution of air by methane gas and the effects of mechanical energy developed by gas spurt is slight in degree. In the coal-mine accidents the causes of death are so much concurred that is is difficult to certify the cause of death. A new concept of a cause of death has been proposed to solve such a problem.
1965年至1978年的14年间，我们实验室对20起煤矿事故中遇难的34名死者进行了尸检，并讨论了他们的死因。在瓦斯和煤尘爆炸中，煤或瓦斯中储存的化学能转化为机械能和热能，作用于人体，导致七种死亡原因。死亡更多是由热能直接或间接导致的，而非机械能。这是在由易燃材料构成的大型封闭地下空间的煤矿爆炸中发现的一个特征。在瓦斯喷出事故中，主要死亡原因是瓦斯取代空气导致缺氧窒息，瓦斯喷出产生的机械能影响程度较轻。在煤矿事故中，死亡原因相互交织，很难确定死因。为解决这一问题，提出了一种新的死因概念。
