Problems solved by technology

[0002] In the modern age when mineral resources are becoming more and more scarce, how to extract the ore in the deposit economically and safely has become a common problem. Rules, artificial and unconstrained mining can easily lead to cross-border mining in the process of ore mining, increasing mining costs, and in the process of ore mining, it is easy to lead to incomplete ore mining, which leads to waste of resources. Mining has become a bottleneck in the development of mining technology

Abstract

The invention discloses a blasting method for mining. The method comprises the following steps of model building, equal-height cutting, determination of a mining direction, determination of the numberof mining roadways, and determination of a mining mode. During ore mining, mining is conducted from bottom to top along an ore body and from inside to outside along an ore receiving roadway. The mining roadways are mined one by one, each mining roadway adopts a two-step mining mode, a three-dimensional space formed by each cutting rectangle and the corresponding contour line is a mining space, and each mining space adopts a fan-shaped deep hole full-lateral blasting method for mining. According to the method, the ore body forms a 3D model, the model is subjected to equal-height cutting to form multiple sets of mining heights, the ore body part in each height is projected, and the mining area at each height is determined through a transverse cutting line and a longitudinal cutting line. Therefore, ore depletion is reduced under the condition of ensuring ordered ore mining, the mining cost is reduced, and the ore body is fully mined.

Description

technical field [0001] The invention relates to the technical field of ore mining, in particular to a mining blasting method. Background technique [0002] In the modern age when mineral resources are becoming more and more scarce, how to extract the ore in the deposit economically and safely has become a common problem. Rules, artificial and unconstrained mining can easily lead to cross-border mining in the process of ore mining, increasing mining costs, and in the process of ore mining, it is easy to lead to incomplete ore mining, which leads to waste of resources. Mining has become a bottleneck in the development of mining technology. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, an object of the present invention is to propose a kind of mining blasting method, by projecting the ore body in a single height, determine the mining area in a single heig...
