Underground three-dimensional modeling technique based on goaf three-dimensional laser scanning method,is a new technology in underground monitoring in recent years.This technology has great significance to digitization of underground engineering structures,deformation calculating and stability analysis of underground structures,aided design in mines,loss and dilution analysis.Application practice in mines has proved that,goaf three-dimensional laser scanning system can be not subjected to operating environment,overcome the problems of little observational data and low efficiency in traditional monitoring methods,achieve non-contact long-distance high-precision measurement and then the three-dimensional model of underground structures will be built up rapidly.Online intelligent tailing ponds monitoring system can monitoring the operation status of tailing ponds online by the way that each sensor on monitoring point real-time obtains the operation data of the tailing ponds,after that the data will be integrated and restructured with multi-information fusion technology,at last it will be calculated in safety analysis module.When the security risks appear,the system will make judgment and warning without delay.As a result,relevant departments will be able to handle that situation in order to make sure no people will get injured.At the same time,the system will put out the operation data of tailing ponds over internet.The relevant supervising officers can get the operation status easily and intuitively from internet.When tailing ponds disaster strikes,relevant departments can also use this system for event tracing,decision support and emergency command and control.
