摘要
阳泉煤业集团平定裕泰煤业有限公司15101工作面为首采面,结合阳煤集团同区域、同煤层矿井在拆除期间采用负压通风经常造成15~#煤层自燃情况,在15101工作面拆除期间,采用局部通风机供风的正压通风,直至工作面拆除完毕封闭,工作面及其回风流内的CO浓度、CO_2浓度、温度均在安全值范围内,未出现煤层自然发火迹象。
Pingding Yutai Coal Industry Co., Ltd., Yangquan Coal Group 15101 working face by first face, in combination with the same area, Yangquan coal mine in the demolition period using negative pressure ventilation often caused by coal spontaneous combustion of 15#. During the demolition in 15101 working face, positive pressure ventilation with local fan, until the working face is closed after working face and back temperature, CO concentration, CO2 concentration, air flow inside were all in the safe range, does not appear signs of coal spontaneous combustion.
