Research status of slope stability and intelligent monitoring technology in open pit coal mine
In the process of open pit coal mining,the stability of high and steep slope directly restricts the safety of mining area and the sustainability of mining work,and poses a great threat to the mining area environment and surrounding building facilities.Using the traditional single instrument or manual monitoring has great limitations.The main problem is that the monitoring position is difficult to fully cover,and the monitoring frequency cannot meet the frequency of mine safety monitoring.Therefore,the accurate and real-time grasp of the mine slope status information and deformation and instability process,can effectively curb the occurrence of serious accidents caused by landslides,and provide a guarantee for the long-term safe production and economic benefits of coal mining enterprises.Based on the stability analysis of open pit mine slope,combined with the research index of the stability evaluation of high and steep slope of open pit coal mine at home and abroad,this paper introduces the content framework of intelligent monitoring of open pit coal mine slope,and puts forward the research idea of combining the stability monitoring of open pit coal mine slope and artificial intelligence monitoring technology.According to the situation and actual conditions of the high and steep slope of the open pit coal mine,combined with intelligent monitoring technology,such as space-based monitoring satellite remote sensing technology,air base monitoring UAV technology,ground foundation monitoring three-dimensional laser scanner and measurement robot and other monitoring instruments,body base monitoring drilling stressor and seepage pressure gauge and other test instruments.Through AI intelligent data analysis and processing,the real-time situation of the high and steep slope in the mining area is obtained,and the full-dimensional intelligent monitoring,analysis and alarm system is established to realize the dynamic interpretation and characterization of the stability information of the high and steep slope in the open-pit coal mine,so as to obtain more accurate,reliable and intuitive slope stability data.In order to provide an important reference basis for the evaluation,design and disaster prevention of safety production and slope stability in open pit coal mine.
