Abstract

In order to make up for the deficiency of the regional monitoring of the traditional gas drainage monitoring system, this paper proposes to build a borehole gas drainage monitoring system with borehole as the monitoring unit, which can dynamically grasp the drainage effect of each borehole in the process of gas drainage in real time, change the large area regional measurement into the measurement of each borehole in the region, and realize the fine monitoring of gas drainage. According to the requirements of borehole gas drainage monitoring system, combined with the characteristics of gas drainage parameters at the borehole orifice, a multi parameter monitoring device for mine gas drainage borehole is developed. The device has the functions of real-time data acquisition of ultrasonic gas flow measurement, non dispersive infrared gas concentration measurement, piezoelectric ceramic gas pressure measurement and platinum resistance gas temperature measurement. It is equipped with the functional human-computer interaction modules such as data display, data storage, data remote transmission and data Wi-Fi transmission, and develops two supporting software, namely, gas drainage analysis software and mobile data acquisition station. According to the actual application requirements, combined with the corresponding measurement standards of the industry, the device has been tested in the inspection unit with the national metrological verification qualification, and the underground industrial test has been carried out in No.2 Coal Mine of Huangling Mining Company to verify the actual application effect of the device. The test results show that the four measurement parameters of the multi parameter monitoring device for mine gas drainage boreholes meet the measurement requirements of the corresponding industry standards, and can realize the accurate measurement of various parameters. Moreover, the device has good working reliability and stability in the actual underground application, which achieves the purpose of gas drainage monitoring with borehole as the monitoring unit, and can be used for gas drainage evaluation, providing strong data support to ensure efficient and safe development of coal and gas resources.
