A control method for improving the quality of limestone mining

Abstract

The invention discloses a control method for improving limestone exploitation quality. The control method comprises the following steps that feed quality indexes of all machining production lines areformulated; according to the physical characteristics of the ore exposed on the surface layer of a new blasting pile, the ore is distinguished, the ore is segmented, the width of the ore segment is recorded, and an ore rock boundary identifier is placed on the blasting pile along the trend of an ore body; blocks are picked and sampled at equal intervals and equal granularity on each segment, the samples are pretreated, the treated samples are placed on a fluorescence analyzer, and the contents of CaCO3, MgCO3, SiO2 and K2O in the samples are detected; according to the detection result and thefeed quality index, a corresponding processing production line is matched on each mineral type segment; and a quality diagram of the blasting pile is compiled. The ore rock boundary identifier is convenient for an operator to find a corresponding operation position; the width of the sample segment is recorded, so that wrong loading of a material source can be prevented; and the quality distribution condition of each segment is detected respectively, so that production management personnel can regulate and control the quality conveniently, and the purposes of accurately controlling the ore quality and improving the resource recovery rate can be achieved.

Description

technical field [0001] The invention relates to the technical field of ore mining, in particular to a control method for improving the quality of limestone mining. Background technique [0002] At present, for the quality control of open-pit limestone mining, the traditional mining method of "simultaneous mining and stripping, and stripping first" is generally adopted. There are many defects, which are mainly reflected in the large change in ore quality along the direction of the ore vein. The deposit position of the ore vein in the previous explosion area cannot be continuous with the next explosion area. The quality of the electric shovel changes greatly during the advancement of the electric shovel, which is very easy to cause product damage. quality fluctuations. [0003] Therefore, how to provide a control method to improve the quality of limestone mining to solve the unfavorable factors of traditional open-pit limestone mining methods, such as low recovery rate and di...
