摘　　要：为了弥补传统瓦斯抽采监测系统区域化监测的不足,提出了以钻孔为监测单元构建钻孔瓦斯抽采监测系统,能够实时动态掌握各个钻孔在瓦斯抽采过程中的抽采效果,将大面积区域化测量转变为区域内部各钻孔的测量,实现了瓦斯抽采的精细化监测。针对钻孔瓦斯抽采监测系统需求,结合钻孔孔口处瓦斯抽采参数的特点,研制了一款矿用瓦斯抽采钻孔多参数监测装置,该装置具有超声波气体流量测量、非色散红外瓦斯浓度测量、压电陶瓷气体压力测量、铂电阻气体温度测量四参数于一体的实时数据采集功能,搭载了数据显示、数据存储、数据远程传输、数据Wi-Fi传输等功能性人机交互模块,并开发了瓦斯抽采分析软件、移动数据采集站两款配套软件。装置根据实际应用需求,结合行业相应计量标准,于具有国家计量检定资质的检验单位进行了计量检测,并在黄陵矿业公司二号煤矿进行了井下工业性试验,对装置的实际应用效果进行了验证。试验结果表明:矿用瓦斯抽采钻孔多参数监测装置的四项测量参数均满足相应行业标准的计量要求,可实现各项参数的准确测量,且该装置在实际井下应用中具有良好的工作可靠性与工作稳定性,达到了以钻孔为监测单元的瓦斯抽采监测目的,能够为瓦斯抽采评价提供有力的数据支撑。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 boreho
