A Mineral Resources Illegal Mining Monitoring System

Abstract

The invention provides a mineral resource illegal mining monitoring system. The system includes optical fiber grating sensors, a bushing, an optic cable, an optical fiber grating demodulator and a demodulation upper computer; the optical fiber grating sensors are fixed in the special bushing; a pipeline is adopted as the bushing, and holes are formed in the casing; the optic cable is used for connecting the optical fiber grating sensors; the optical fiber grating demodulator is used for solving wavelength changes; and the demodulation upper computer processes wavelengths, performs solving by using a relevant algorithm to obtain the position of a vibration region. With the mineral resource illegal mining monitoring system provided by the technical schemes of the invention adopted, the problems of high possibility of being corroded of the sensors, small monitoring range, and difficulty in accurately positioning an illegal mining region in real time of traditional acoustic emission technologies and microseismic monitoring technologies can be solved.

Description

Technical field [0001] The invention relates to the field of underground mining engineering, in particular to a monitoring system for illegal mining of mineral resources. Background technique [0002] With the development of fiber grating technology, the application of fiber grating sensing monitoring has become more and more extensive. Its transmission uses light as an information carrier, and there is no direct connection with electrical signals during its transmission. In some environments where electrical signals cannot be reached, such as electromagnetic interference, strong radiation, flammable, explosive, and highly corrosive environments, it has an ideal effect. It is widely used in civil engineering, aviation, shipbuilding, electric power, petroleum, and building structural health monitoring. Compared with other traditional hydraulic and electrical measuring sensors, fiber grating sensors are safer, more stable, and more accurate. high. The use of quasi-distributed opt...
