1974至1986年期间,苏联煤炭工业部的煤矿约有8％的外因火灾是由矿井设备的故障造成的,而这些故障是由矿井设备部件中摩擦零件的表面摩擦发热引起的。例如,在以苏共第二十五次代表大会命名的矿井(属马卡耶夫煤炭公司)中СП—63М型输送机机头由于结构不符合规定,钢环卡在机头架固定侧板和驱动轴上右边旋转链轮间而产生摩擦引起发热,温度高达310℃。钢环的发热表面成了工业12号矿物油燃烧的热源(燃
Between 1974 and 1986, about 8% of the external fires at coal mines in the Soviet Union’s coal industry were caused by failures of mine equipment caused by surface friction heating of frictional components in mine equipment components. For example, in the mine (Makayev Coal Company) named after the Twenty-fifth CPSU СП-63М-type conveyor head due to structural non-compliance, the steel ring card in the headstock fixed side panels And drive shaft on the right side of the sprocket between the friction caused by fever, the temperature up to 310 ℃. The heating surface of the steel ring has become a heat source for industrial 12 # mineral oil combustion
