Ore drawing automatic control method, controller, ore drawing machine, system and storage medium

Abstract

The invention discloses an ore drawing automatic control method, a controller, an ore drawing machine, a system and a storage medium. The method comprises the steps: firstly, obtaining an average oreloading volume V and an ore pile average height H corresponding to the full load of a mine car; then, in the ore drawing process, the volume Vi of the ore pile in the current mine car and the height Hi of the highest point of the ore pile are detected; whether the current ore drawing amount meets the requirement or not is recognized based on the ore drawing model; wherein if the ore drawing modelis met, the current ore drawing amount meets the requirement, if the current ore drawing amount meets the requirement, ore drawing is stopped, and the ore drawing model is used for judging whether themine car is full or not by comparing the real-time volume and the standard volume of an ore pile and the real-time height and the average height of the ore pile in the ore loading process. By means of the method, on one hand, automatic ore drawing control is achieved, the problem of manual remote control ore loading is solved, and on the other hand, the influence of large rocks can be effectivelyreduced.

Description

technical field [0001] The invention relates to the technical field of underground operations, in particular to an automatic control method, device, system and storage medium for ore drawing. Background technique [0002] The environmental conditions of underground mining operations are complex, harsh and sensitive, and it is difficult to fundamentally guarantee the life, health and safety of mine operators. Underground mines should keep up with the pace of the times, and mining technology innovation has become an urgent need. Through the continuous research and development of new technologies, the mining industry has gradually shifted from traditional manual and mechanized operations to fewer and unmanned operations, reducing underground workers or long-term remote operators in the office, and enabling workers to change from complex and harsh underground environments or monotonous and heavy The office environment can be liberated, thereby improving mining efficiency, ensur...

AI Technical Summary

Problems solved by technology

[0004] However, judging whether the ore is full in the current research is generally by weighing the mine car to determine whether it is full, and this has the following defects: First, this method cannot judge whether there are large pieces in the falling ore. A large piece of ore falls, and the accumulation of large pieces of ore may make the height of the stone exceed or almost exceed the mine cart, and continuing to release the ore will cause the subsequent falling ore to fall out of the mine cart

Secondly, this method needs to install the sensor on each carriage or under the track. The former is not only difficult to maintain and the cost is high, but the latter cannot eliminate the error caused by the falling ore
