风电闭锁控制技术在东滩煤矿掘进工作面的应用

Wind and Electric Interlock Control Technology of Air Duct Sensor Applied to Heading Face in Dongtan Mine

为实现煤矿掘进工作面局部通风机停风或风筒脱节时的风电闭锁功能,确保风电闭锁功能的灵敏、可靠,保障工作面安全生产,将风筒传感器安装在掘进工作面风筒的末端位置,通过风筒传感器并入矿井安全监控系统,对掘进工作面风电闭锁开关进行就地控制,实现风电闭锁功能。

In order to have the wind and electric interlock function when the local fan stopped the operation or the air ducts disconnected in the heading face of the mine,to ensure the sensitivity and reliability of the wind and electric interlock function and to protect the safety production of the heading face,the air duct sensor shall be installed at the end location of the air duct in the heading face.When the sensor was in a connection with the mine safety monitoring and control system,a site control could be conducted to the wind and electric interlock switch at the heading face and the wind and electric interlock function could be realized.
