Beiminghe Iron Mine In The Research Of Big Structures And High-performance Low-depleted Mining Method

This article through the analysis of "big structures and high performance low-depleted mining technology" in Beiminghe Iron mine problems arising from the application, Identify the reasons of the problem, the ore drawing theory and the actual union, improve the production management and optimizing process parameters, To improve technical indexes in recovery, reduce the mining cost and reasonable use of mineral resources targets.In this paper by gathering ore test data, studies the ore and ore dilution rate, the relationship between grade, draw curve chart, and solving the linear equation for determining the conclusion conformity, to guide the production drawing management,loss control dilution index;Through the contrast test, determine depleted sources of waste rock, analysis to verify Beiminghe iron mine structure parameters under the condition of blownoff-ore morphological characteristics, the study of cause factors affect the morphological development, and through the improvement way of drawing method, optimization of ore removal effect. Through production practice and experiment method study demonstrates the influence of various production factors,cause analysis, to find the internal and external factors and the intrinsic relationship between the structural parameters, seek the feasibility of the optimization of structure parameters to improve the production conditions; Analysis blownoff-ore conforms to the situation between the form and structure parameters, structural parameters of the proposed adaptive blownoff-ore form. By reference to the production practice and experiment data show, by using the theory of mining science and research to determine the structural parameters optimization.This paper puts forward the direction of the structural parameters optimization, and obtained the corresponding research conclusion.Beiminghe iron mine removal is built and the impoverishment rate, the linear relation model between simplify the production index, the relation between ore and convenient for production management;Inference and proof Beiminghe iron mine caving ore blownoff-ore morphological characteristics,summarizes the developing blownoff-ore of various factors, provides a theoretical basis for drawing management; According to blownoff-ore form, we obtain the better suitable for structural parameters of the north Ming river iron ore, this article research results for similar mines has certain application value.
