崔家寨矿6号煤层井田两翼煤炭燃烧特性的试验研究

Experimental Research on Burning Characteristics of No. 6 Coal Seam at Mine Field's Two Wings inCuijiazhai Coal mine

在辐射能量为50 kW/m2的条件下用锥形量热仪对崔家寨矿6号煤层井田东西两翼的4个煤样进行了燃烧特性试验研究。研究表明:东翼煤样燃烧过程中产生的的CO峰值浓度、CO平均产生量超过了西翼工作面煤样,而西翼煤样燃烧过程中的热释放速率、总释放热和比消光面积超过了东翼煤样。在烟释放速率和总生烟量方面,井田两翼煤样出现了一定的差异,西翼11605工作面第一个煤样最高,东翼11606工作面第一个煤样次之,其余两个煤样差别不大。

Under the condition of radiation energy given 50 kW/m 2 , by using cone calorimeter , the experi-ments are made to research burning characteristics of 4 coal samples which are taken from Two Wings （i.e.the west wing and east wing） of No.6 Coal Seam in Cuijiazhai Coal mine.The results show that the CO peak concentration and average produce amount which are produced in the course of coal samples taken from east wing burning are more than that of coal samples taken from west working face.However, the results also show that, in the course of coal sample taken from west wing burning , heat release rate, total heat release and spe-cific extinction area are more than that of coal samples taken from east wing.In respect of smoke produce rate and total smoke release, there is certain difference that the first coal sample taken from 11605 working face in west wing is the highest, and the first coal sample taken from 11606working face in east wing takes second place, and there is little difference in the others coal samples.
