摘要
为了弄清同忻矿8309综放面高温热害来源,从火成岩、地温、通风状况、采空区遗煤氧化等方面对工作面高温热害(源)进行了分析,得出地表空气温度直接影响矿内进风巷的温度,由于进风距离比较长,通风压缩热等,致使进风巷的温度23.8℃~24℃。研究表明,采空区遗煤低温氧化散热未对采面的气候条件产生显著影响。
In order to find out the source of high temperature heat damage in 8309 fully mechanized top-coal caving face of Tongxin Coal Mine, the high temperature heat damage (source) in working face was analyzed from igneous rock, ground temperature, ventilation condition and oxidation of residual coal in goaf. It was concluded that the surface air temperature directly affects the temperature of the mine air intake roadway. The temperature of the air intake roadway ranges from 23.8 to 24 ℃ due to the long distance of air intake and the heat of ventilation compression. The results show that the low temperature oxidation heat dissipation of residual coal in goaf has no significant influence on the climatic conditions of coal face.
