[Abstract]:As the priority development strategy of China's coal industry, the scale of open-pit mining has been expanded and developed rapidly. At the same time, it also leads to landslides and other geological disasters occur frequently. Landslide, as a serious natural disaster, threatens the safety of people's life and property, and may cause huge economic losses. Slope monitoring is an important means and measure to ensure the safety of slope in construction and service life. GPS technology has the advantages of high positioning accuracy, not restricted by climatic conditions and common viewing conditions, and highly automatic and intelligent. The application of GPS technology in slope monitoring of open-pit mines can not only meet the requirements of slope monitoring accuracy, but also help to realize the intellectualization and automation of slope monitoring process. Based on the theoretical knowledge of GPS positioning technology, this paper applies GPS positioning technology to the monitoring and prediction of slope stability in open pit. In order to solve the problem that the cycle slip is easy to occur in the process of GPS positioning, a method combining carrier phase difference method and polynomial fitting method is proposed to detect and repair the cycle slip. A slope monitoring data processing system based on GPS is designed and implemented. The system can automatically realize the functions of slope surface displacement monitoring, internal displacement monitoring, cross-section analysis, real-time data display, historical data query, statistical analysis of monitoring quantity and monitoring prediction and alarm.
