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 the following conclusions have been obtained, summarizing the exogenous findings on the bodies. At 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. Mechanical energy produces diverse injuries in the human bodies, among which only the coal-particle impression demonstrates directionality. Thermal energy produces burns when it acts directly upon the human bodies and among diverse substances produced by heat from the explosion coal-tar like substance adheres to the skin, soot adheres to the inside of the air passage, carbon monoxide produces carbon-monoxide hemoglobin after entering the blood through the lung. At gas spurt mechanical energy stored in methane which is adsorbed on coal under high pressure is set free to produce injuries on the human bodies, but thermal energy does not develop. The action of diverse sorts of energy upon the body differs extraordinarily according to the distance from an epicenter or the irregularities of pit, producing various exogenous findings on the bodies. Accordingly, general rules cannot be established to assume the sort and mode of an accident and it should be considered on a case-by-case basis.
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具尸体进行了尸检，现将尸体外部检查结果总结如下。在瓦斯和煤尘爆炸时，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。机械能会对人体造成多种损伤，其中只有煤颗粒压痕显示出方向性。热能直接作用于人体时会产生烧伤，爆炸产生的热量所形成的多种物质中，类似煤焦油的物质会附着在皮肤上，煤烟会附着在气道内部，一氧化碳通过肺部进入血液后会生成碳氧血红蛋白。在瓦斯喷出时，高压吸附在煤上的甲烷储存的机械能释放出来对人体造成损伤，但不会产生热能。各种能量对人体的作用会因与震源的距离或矿井的不规则情况而有极大差异，从而在尸体上产生各种外部表现。因此，无法制定通用规则来推测事故的类型和方式，应根据具体情况进行考虑。
