Abstract: iming at the problems of data multi-source heterogeneity, large data volume and data isolated islands in the process of gas drainage and gas power generation monitoring in Guizhou Province, based on data fusion and mobile query technology, the design concept of real-time monitoring and mobile query platform for coal mine gas drainage and gas power generation in Guizhou Province is proposed. The running process of platform system acquisition, fusion, release, sharing, mobile query and abnormal push is designed. The construction contents of the data fusion and mobile query of gas drainage monitoring system, the data fusion and mobile query of gas power generation monitoring system, the development of monitoring data network management terminal and the construction of push mechanism for abnormal monitoring data are elaborated in detail. The platform construction realizes the remote online real-time monitoring. The platform construction realizes data remote online real-time monitoring, multi-dimensional data comparison analysis, abnormal data real-time diagnosis and early warning and mobile query data, which provides the effective technical means for the subsidy fund cashing of mine gas drainage and gas power generation.
