Device for monitoring lower goaf stability in open-pit iron mining

Abstract

The invention relates to a device for monitoring lower goaf stability in open-pit iron mining. The device comprises a signal acquisition system used for acquiring and sending signals as well as a single receiving, analyzing and processing system, and is characterized in that the signal acquisition system is a front-end monitoring unit comprising a plurality of integrated measuring heads with the same structure, a plurality of data acquisition instruments with the same structure, a plurality of wireless signal transmitting units with the same structure and a wireless relay arranged at a commanding point of an open pit, and the data acquisition instruments are connected with the integrated measuring heads through power lines; the single receiving, analyzing and processing system comprises asignal receiving controller, a far-end monitoring center PC host connected with the signal receiving controller as well as a database server. The device has the following advantages: by means of the multiple integrated measuring heads as well as application of signal acquisition, transmission, conversion, emitting and receiving technologies, the signal receiving capacity of the device is improvedeffectively, a multi-channel monitoring system with high sensitivity is formed, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the technical field of safety measurement and monitoring in mining, in particular to a stability monitoring device for a lower goaf in open-pit iron mining. Background technique [0002] In most of the iron ore mines that have been converted from underground mining to open-pit mining in my country, when the original mining area was mined, the mining order was chaotic at the beginning, and illegal and unplanned random mining and indiscriminate mining were common, leaving a large number of unidentified lower mined-out areas. , with the gradual depletion of shallow mineral resources in open-pit mining, open-pit iron ore mining continues to go deep, resulting in deterioration of mining conditions after iron ore mines are converted to open-pit mining, and serious safety hazards have become the most important factors affecting the safe production of iron ore mines. Hazard sources restrict the sustainable development of iron ore mines a...
