摘要
为研究华阳二矿井下带式输送机大巷中的煤与胶带摩擦生热致灾的问题,利用YRH700红外热成像仪和等比例胶带输送机摩擦起火模拟器搭建了物理相似模拟实验台,选用华阳二矿二号井的瘦煤作煤样进行实验。结果表明,随着摩擦时间的增加,煤与胶带之间的接触由点到线再到面,在沿胶带长边方向上,煤样和胶带的接触位置形成具有温度梯度分布的“高温带”,该“高温带”的温度与摩擦时间呈正比。
In order to study the problem of heat disaster caused by friction between coal and belt in the main roadway of belt conveyor in Huayang No.2 Mine,a physical similarity simulation experiment platform was built by using YRH700 infrared thermal imager and equal proportion belt conveyor friction fire simulator,and the lean coal of No.2 Mine in Huayang No.2 Mine was selected as the coal sample for the experiment.The results show that with the increase of friction time,the contact between coal and tape is from point to line and then to surface.In the direction along the long side of tape,the contact position between coal sample and tape forms a'high temperature zone'with temperature gradient distribution,and the temperature of the'high temperature zone'is proportional to the friction time.
