比利时瓦特斯哈依矿,在井下通风监视程序中,使用压差遥测计测量压差,使用湿度遥测计测量空气湿度。本文介绍该矿所用的这两种遥测计。一、压差遥测计该遥测计用来在地面上遥测井下的风流压差。所谓风流压差包括风机所产生的压差,一个网络支路两端的压差,为测风量使用的减压器件,如皮托管、锥形喷咀等所产生的压差。
The Wattshah mine in Belgium used a pressure gauge telemetry to measure differential pressure and a humidity telemeter to measure air humidity in a downhole ventilation monitoring program. This article describes the two telemeters used in the mine. First, the pressure differential telemetry The telemetry used to telemetry the ground on the ground flow pressure difference. The so-called wind pressure difference, including the pressure generated by the fan, a network of the two ends of the pressure drop, the wind measurement for the use of pressure reducing devices, such as pitot tube, tapered nozzle and other pressure difference.
