高瓦斯掘进工作面可靠供风技术的研究

Study of Reliability of Air Supply Technology on High Gas Tunneling Face

针对局部通风机停风会造成盲巷甚至瓦斯超限这一重大问题,发明了临时供风装置。芦岭煤矿井下实际应用过程表明,该装置能有效解决高瓦斯掘进工作面无计划停风时现场通风、瓦斯管理的难题,是一项值得推广的实用技术。

For the problem of blind alley and even the gas overlimit can be caused by he auxiliary fan abnormal working,the temporary air supply device was invented.Luling coal mine actual application process indicates that the device can effectively solve the problem of ventilation and the gas management when unplanned stop for wind of high gas tunneling face.And it is a worthy of popularization practical technology.
