Underground feed port lump ore treatment construction method based on data simulation

Abstract

The invention discloses an underground feed port lump ore treatment construction method based on data simulation. A screen grid is mounted at a feed inlet of a crusher; lump ores are isolated on the upper surface of the screen grid; and the fixed hydraulic crusher is mounted at an attachment of the screen grid. The underground feed port lump ore treatment construction method comprises the following construction steps of: 1, acquiring field data; 2, carrying out analog simulation on a construction field; 3, determining a mounting position; and 4, carrying out preparation before mounting a device. The underground feed port lump ore treatment construction method has the advantages that the fixed hydraulic crusher adopts a motor to drive a hydraulic system, does not emit exhaust gas and is high in working efficiency and low in cost; the lump ores on a grating of a jaw crusher can be quickly treated, and the production efficiency is improved; data in the feed inlet is acquired on site, the working range of the device is simulated in a computer, the mounting position of the fixed hydraulic crusher is determined, the optimal working range of the device is guaranteed to meet the on-site using requirements, repeated construction is prevented, and the construction progress is quickened.

Description

technical field [0001] The invention relates to a large ore processing method, more specifically, relates to a data simulation-based construction method for processing large ore at an underground feed port. Background technique [0002] At present, the mine adopts the method of drilling holes in the mining area and then installing explosives. After the blasting, the ore is transported out to the crushing port by rail trolley for crushing. The crushing port in the mine generally adopts a jaw crusher, and the jaw crusher requires that the input stone is not larger than 500mm. , the ores mined by blasting cannot all meet the requirements, and the particle size of individual large ores reaches 1000~2000mm. In order not to cause blockage of the jaw crusher and cause production stoppage, a grid is usually installed at the feed port of the crusher to isolate the large ores. On the grid, however, after the accumulation of large pieces of ore, it will affect the small ore to enter th...

[0002] At present, the mine adopts the method of drilling holes in the mining area and then installing explosives. After the blasting, the ore is transported out to the crushing port by rail trolley for crushing. The crushing port in the mine generally adopts a jaw crusher, and the jaw crusher requires that the input stone is not larger than 500mm. , the ores mined by blasting cannot all meet the requirements, and the particle size of individual large ores reaches 1000~2000mm. In order not to cause blockage of the jaw crusher and cause production stoppage, a grid is usually installed at the feed port of the crusher to isolate the large ores. On the grid, however, after the accumulation of large pieces of ore, it will affect the small ore to enter the crushing port. Usually, a fixed hydraulic crusher is installed at the attachment of the grid for processing. The advantage of the fixed hydraulic crusher is that the motor drives the hydraulic system, and there is no Exhaust gas discharge, high working efficiency, however, the fixed hydraulic crusher is fixed installation, so it is very important to combine the working position of the crusher with the working range, otherwise it is easy for the crusher to be unable to process and open the ore, resulting in reinstallation and delaying the construction progress ,affect production
