Automatic ore-drawing control method, controller, ore-drawing machine, system and storage medium

Abstract

The invention discloses an automatic control method for ore drawing, a controller, an ore drawing machine, a system and a storage medium. The method first obtains the average ore loading volume V corresponding to the full load of the mine car and the average height H of the ore pile; Detect the volume V of the ore pile in the current mine car during the mining process i and the height H of the highest point of the ore pile i , and identify whether the current ore drawing amount meets the requirements based on the ore drawing model. If the ore drawing model is satisfied, the current ore drawing amount meets the requirements. If the current ore drawing amount meets the requirements, the ore drawing is stopped. The ore drawing model is loading In the process, it is judged whether the mine car is full by comparing the real-time volume of the ore pile with the standard volume, and the real-time height of the ore pile with the average height. The present invention realizes ore-drawing automatic control through the method on the one hand, solves the problem of manual remote-control ore loading, and on the other hand, can also effectively reduce the influence of large rocks.

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...

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
