近水平突出煤层回采工作面下行通风应用研究
Field experiments using downward ventilation were studied and the gas emission and distribution laws at the goaf working face were discussed.
结果表明,在采用下行通风后,采空区绝对瓦斯涌出量为上行风时的80%,工作面φ(CH4)下降了75%,瓦斯不再超限。
Automatic monitoring realization of down channel based on cycle data transmitting(CDT) protocol;
循环式CDT规约远动下行通道自动监视的实现
It is unable to determine whether down channels are at normal situation without down-instruction during normal time.
在电网调度自动化系统中,远动传输规约采用部颁CDT方式,因为平时没有下行命令,不能判断下行通道是否正常,为了使运行人员能及时了解下行通道的运行状况,提出了基于调度自动化系统DF8900的下行通道自动测试方法,实践证明该方法行之有效。
