Dynamic mine shoveling, transporting and dumping efficiency optimization system and method

Abstract

The invention relates to a dynamic mine shoveling, transporting and dumping efficiency optimization system and method, and belongs to the technical field of mining. The system comprises a GPS system of a shoveling device, a dynamic weighing system of an automobile transport device, a crusher of a rocking dumping device and a belt control system. The load queue length of the system in unit time is calculated by using a queuing theory model, a mathematical optimization method is used to calculate the optimal ratio of the automobile to the shoveling devices, high efficiency of a belt is kept in unit time, the automobiles and the shoveling devices are scheduled automatically, the mine feeding amount of the belt is controlled, the production efficiency is improved, loss is reduced, great convenience is provided for production command, and the practicality is very high.

Description

technical field [0001] The invention belongs to the technical field of mining, and in particular relates to a dynamic optimization system and method for mine shovel, transport and discharge. Background technique [0002] At present, in the mining and rock removal operations of open-pit mines, most of the processes are: shoveling-motor transportation-belt rock removal. Usually, the ratio of vehicles and shoveling equipment is used for scheduling and production in the following ways: [0003] 1. Manual intervention, the whole process is based on experience, dispatching vehicles and shoveling equipment through walkie-talkies, mainly based on production experience and actual conditions; [0004] 2. Automatic allocation of vehicles through the GPS system. GPS uses a reasonable algorithm to allocate vehicles according to the distance of the shovel and the vehicle to improve the production efficiency of the mine. The influence degree of GPS system on mine production efficiency is ...

AI Technical Summary

Problems solved by technology

[0005] However, in the production practice of mine shovel loading-automobile transportation-belt rock removal, it is often difficult for the GPS dispatching system to play a role due to various factors. Sometimes the information cannot be accurately and timely fed back to the dispatching room, which brings difficulties to the GPS shunting system

Second, under normal circumstances, the GPS system will automatically dispatch vehicles and shoveling equipment. If there is an abnormal situation on site, the dispatcher may make a wrong judgment on the site situation and issue wrong instructions, causing production chaos

Third, drivers of vehicles and shoveling equipment sometimes violate instructions or misunderstand instructions, causing confusion on the scene

Fourth, the speed of dump trucks on site is inconsistent, which indirectly affects the reasonable shunting of the GPS system; fifth, the GPS signal is unstable and the network transmission has dead ends, which has a direct impact on the dispatching system; sixth, the GPS mine car dispatching system The failure of various hardware parts and intelligent terminals will also cause chaos on the scene

[0007] In addition, in the process of shoveling-vehicle transportation-belt rock removal, belt transportation involves many links. No matter which belt has a problem, it will directly affect the rock removal operation; more importantly, the carrying capacity of the belt directly affects the vehicle and shoveling equipment. Ratio, if there are too many vehicles, it will be crowded, and if there are too few shoveling equipment, the belt transportation efficiency will not be able to be exerted; at the overturned place of the rock crusher, the operator adjusts the feeding speed of the belt according to the density of the vehicle to ensure that the crusher breaks The material level of the bottom silo of the mine is about 50%; sometimes when there is no car, it is necessary to stop the belt running, which brings inconvenience to the production personnel and reduces production efficiency
