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

Abstract

The present invention relates to a lower goaf stability monitoring device in open-pit iron mining, including a signal acquisition system for collecting and sending signals; a signal receiving, analyzing and processing system, characterized in that: the signal The acquisition system is a front-end monitoring unit, including multiple integrated probes with the same structure, multiple data acquisition instruments with the same structure connected to the integrated probes through power lines, multiple wireless signal transmitting units with the same structure, and wireless signal transmission units set at the commanding heights of the open-pit pit. In the relay station, the signal receiving, analyzing and processing system includes a signal receiving controller, a remote monitoring center PC host and a database server connected to the signal receiving controller. The advantages of the present invention are: through the application of multiple integrated probes and signal acquisition, transmission, conversion, emission and reception technology, the signal receiving ability of the instrument is effectively improved, a multi-channel high-sensitivity monitoring system is formed, and safety Hidden danger.

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...
