Method for determining height of strip mine dragline dumping operation platform

Abstract

The invention provides a strip mine dragline pouring operation platform height determining method. The method comprises the steps that a first relation model is established according to a preset relation model of the dragline pouring operation platform height and the dragline operation unit sectional area; fitting the obtained historical muck pile curves under different throwing blasting step heights in the strip mine pouring operation to obtain a second relation model, and in the second relation model, different throwing blasting step heights correspond to different fitting constants; substituting the second relation model into the first relation model to obtain a third relation model; and substituting the raw coal production capacity of each mining belt of the strip mine and the average thickness of the dragline mining belt into the third relation model, and determining the height of the dragline dumping operation platform. According to the method, the technical problem that in the prior art, the operation efficiency is low due to the fact that the height of the dragline pouring operation platform cannot be determined is solved, and by means of the method, the dragline pouring operation efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the field of coal mines, in particular to a method for determining the height of a dragline dumping operation platform in an open-pit mine. Background technique [0002] The formation process of the open-pit mine: strip off the floating soil and surrounding rock covering the upper part of the ore body and its surroundings, transport the waste rock to the dump, and directly extract the ore from the open ore body. The basic operation process of the current drag shovel dumping process is: after the rocks 40 meters to 50 meters high above the coal seam roof are thrown and blasted, a blast pile is formed on the working face, a standing step (platform) is formed on the blast pile, and then the blast pile is formed. The material peeled from the upper layer of the pile is discharged to the edge of the working face to form a secondary standing step, and finally the pile is dumped by a drag shovel, and the material is discharged to the d...

Problems solved by technology

[0005] Based on the above problems, the present invention proposes a method for determining the height of the open-pit mine dragline shoveling operation platform, which solves the technical problem of low operating efficiency caused by the inability to determine the height of the dragline shoveling operation platform in the prior art. The provided method for determining the height of the open-pit mine dragline shovel pile operation platform significantly improves the efficiency of the dragline shovel pile operation
