Design of intelligent control software for whole mine gas extraction based on cross-platform architecture

The existing coal mine gas extraction anomaly recognition needs to rely on manual assistance to view related data analysis, lacking autonomous and intelligent analysis means. The capability of timely handling of abnormal extraction is weak, and the multi-system linkage control function in case of gas disaster is lacking. The software deployment environment is single, and cross-platform and cross-end application access cannot be realized. In view of the above problems, a set of intelligent control software for whole mine gas extraction based on cross-platform architecture is designed. The software consists of two parts: company side and mine side gas extraction intelligent control software. By adopting technologies such as extraction multi-source data acquisition, extraction drill hole aided design, extraction data analysis, extraction equipment operation and maintenance management, extraction GIS display, extraction fusion control, the global visualization of an extraction system is realized. A comprehensive data display of mine up and down integrated extraction has been formed, and a multi-level data traceability access mechanism has been established. The comprehensive analysis of mathematical and physical characteristics of extraction data, extraction evaluation characteristics, equipment fault characteristics, extraction anomaly characteristics, and borehole trajectory characteristics is realized by constructing thematic data characteristic graph. In case of abnormal extraction, the software will automatically link with the broadcasting system to inform the evacuation personnel in the dangerous area of gas emission. At the same time, the software will link the ventilation monitoring system to strengthen the ventilation in the abnormal area. The software automatically pushes the abnormal alarm message to the relevant person in charge through the message push strategy, so as to solve the extraction problem in a timely and rapid manner. The Docker technology is adopted to realize the cross-platform design of the software. The SQL Server database and Web terminal application are deployed in the Docker environment. Native HTML technology combined with responsive layout style is adopted to realize multi-terminal access such as HTML webpage, mobile APP and WeChat applet. The field application results show that the software can meet the access needs of two levels of users of the group company and mine. The software effectively improves the efficiency of mine extraction, and enhances the capability of mine in gas extraction evaluation, extraction abnormal disposal and extraction utilization. The software reduces the occurrence rate of mine gas abnormal accidents.
