煤矿井下矿压综合监测系统的研究与应用.pdfVIP

摘 要 煤矿井下伤亡事故较多，顶板事故在矿井采掘工作面生产过程中经常发生。为了保证 巷道围岩的稳定，避免冒顶事故的发生，研制了煤矿井下矿压综合监测系统。对煤矿井下 矿压综合监测系统的各组成部分——矿压监测分站、巷道矿压监测仪、工作面矿压监测仪 和无线数据收发仪(PDA)进行了软硬件的设计，并利用巷道矿压监测仪在榆家梁矿和石圪 台矿对锚杆锚索受力、深基点位移等巷道围岩结构和围岩变形规律进行了观测研究。 煤矿井下矿压监测系统提供井下通讯电缆和无线传输两种数据传输模式，井下通讯由 CAN 总线相连接，转换模块负责将 CAN 信号转换成上位机可识别接收的信号，无线传输 由无线数据收发仪进行接收和传输。论文还利用ASP （Active Server Page,动态网页技术） 技术对系统进行了网页设计，以对系统进行实时监管。 实际应用结果表明，矿压综合监测系统性能良好。 关键字： 监测仪；收发仪；监测分站 - I - Abstract In mine underground often happend serious disasters and deaths and injuries constantly. In which roof carving accident in tunnelling face often occurs in production. In order to guarantee the stability of surrounding rock and avoid avoid roof caving accidents, so the dissertation will be designed and researched The Research And Application of Mine Pressure System in Mine Underground.Dissertation The Research And Application of Mine Pressure Comprehensive Monitoring System in Mine Underground. The system have been composition by Mine pressure monitoring substation 、Roadway underground pressure monitor 、Coal face of mine pressure monitors 、Personal Digital Assistant(PDA),and account for hardware and software. Among them, the roadway underground pressure monitor in Yujialiang mine and Shigetai mine and on bolt and anchor cable force, deep base point displacement and deformation law of surrounding rock of roadway surrounding rock structure and observational study was conducted, and reached the purpose of monitoring. Mine Pressure Comprehensive Monitoring System in Mine Underground provides two kinds of communication cable and wireless data transfer mode. Underground connected by the CAN bus communication conversion module is responsible for the CAN signals into the ho
