Coal mine gas drainage multi parameter monitoring system makes up for the lack of regional monitoring of traditional gas drainage monitoring system. The system can dynamically grasp the drainage effect of each borehole in the process of gas drainage in real time. The large area regional measurement is transformed into the monitoring of each borehole in the region. By setting multiple groups of drilling multi parameter monitoring system, fine monitoring of gas drainage is realizes.
The gas drainage monitoring system is composed of three parts, borehole multi parameter monitoring device, underground “ring” communication network and gas drainage analysis software platform. Parameter monitoring device is responsible for the data measurement and collection of single borehole. Through “ring” communication network, real-time data, including temperature, pressure, concentration and flow data, etc, are packaged and uploaded to analysis software platform on the surface, where data storage, display, sorting, evaluation and analysis, are realizes.
