Abstract

The invention relates to an ore rock contact surface tracking method, which belongs to the technical field of ore extraction. By attaching ferromagnetism powder on explosion broken ores and / or surrounding rocks of ore rock contact surfaces, arranging a monitoring device on an ore tapping hole or an ore removal working surface of a scrapper and dynamically monitoring ferromagnetism abnormal signals of ore rock contact surface ores or dead rocks discharged by a mine mouth through detecting instruments on site, the ore rock contact surface tracking method can improve the accuracy and timeliness of judgment of the ore rock contact surfaces, provides reliable foundation for draw control and is favorable for controlling loss index of ores.

Description

Technical field

[0001] The present invention involves a method of contact with the contact surface of the mine, especially a mining traceing method of ore mining technology. Background technique

[0002] The collapse method is a method of mining method with high strength, low cost, and safe operation.Judging the contact surface of the ore and wastestone, the identification ability is limited; if the results of the sampling test of the ore rock are judged, the representative and timely effectiveness of the on -site sampling sampling will cause the losses or poverty to be controlled by the losses or poverty of the ore.At present, there is a kind of dyeing identification method on the contact surface of the mine. However, because the ore rock is prone to a large amount of powder during the blasting and decentralization of the ore, it is easy to mix with the chromosome to make the chromosomal also difficult to identify with the naked eye.
