为预防矿山采矿过程中突发事故的出现,如坍塌,滑坡等,提出基于ZigBee和MCGS的矿山安全监测系统。通过采集矿山湿度和压力的实时数据,监测并判断是否会有异常情况发生,达到提前预警的目的,保障作业人员的安全。通过ZigBee网络将各类传感器的数据从终端节点采集并传输至协调器,随后协调器通过串口将数据传输至电脑,利用上位机软件MCGS进行数据的可视化和分析处理。若实时数据显示异常,则由后台监测人员通过上位机联动PLC打开报警器和应急灯,及时提醒并协助矿山作业人员安全撤离,极大提高了矿山作业的安全性。
The magmatic rocks in the Muniushan complex zone intruded via a concentric“ reverse zonation”accretion pattern. During the Late Yanshanian period, the Weideshan magmatic sequence intruded around the outermargins of the earlier Linglong sequence, introducing additional heat and ore‑forming materials. This provided both anenhanced fluid‑driving force and vertical migration pathways, thereby facilitating the transport and precipitation ofore‑forming fluids.Based on detailed field observations of structural features in the Linshisi Mountain area and acomprehensive analysis of regional data and geological exploration results, it is inferred that during the Early Cretaceous,under a compressive stress regime caused by the high‑angle oblique subduction of the West Pacific Plate beneath theNorth China Plate in a NNW direction, left‑lateral strike‑slip compression dominated the tectonic activity in theMuniushan complex zone. Multiple episodes of tectonic superposition led to the formation of high‑angle shovel‑shapedfaults in the shallow subsurface and broad, gently dipping brittle‑ductile transition zones along major deep structures.Atmospheric precipitation carrying abundant carbonate melts and gold‑bearing fluids converged in these deep, gentlydipping brittle‑ductile transition zones. These zones, with ample space and significant carbonate melt involvement,facilitated the formation of thick pyrite-carbonate vein‑type gold deposits (similar to the“Liaoshang‑style”gold deposits).Portions of the gold‑bearing fluids continued to migrate upward, and in shallow brittle faults, structural fractures, andinterlayer slip zones with smaller ore‑hosting space, smaller‑scale structurally altered‑rock type gold deposits (such asthe Guocheng deposit) were formed.Thus, the gold deposits in the Muniushan complex zone are the result of ore‑formingfluids from a common source and structural regime, forming mineral bodies of different scales and types under variedstructural styles and metallogenic environments.
