Embodiment Construction

[0042] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0043] The mining method of segmental caving without pillars is adopted, and the design parameters of the stope are: the segmental height is 15 meters, and the approach distance is 20 meters. The ore body is in a north-south direction, with a length of about 800 meters from north to south and a width of about 500 meters from east to west. The azimuth of the ore body is 20° from north to east.

[0044] According to the above-mentioned design parameters, use software to generate the stope and each stratified recovery approach contour line 1 . The present invention is preferably completed by secondary development of the professional three-dimensional digital mining ...

Abstract

The invention discloses a true three-dimensional mining blast unit body modeling method which is applied to a subsection caving mining method without sill pillars. The computer three-dimensional modeling technique is utilized to model a mining blast unit body so as to achieve true expression and independent and omnibearing three-dimensional display of the blast unit body. The purpose of cognitive comprehensiveness and management refine on the blast unit body is achieved. The true three-dimensional mining blast unit body modeling method comprises the following steps of designing distance according to extraction approaches, generating all central lines of the distance of the extraction approaches a main layer and an upper layer on the XY plane, forming line files to be stored, simultaneously cutting extraction approaches of a blast unit body to be built and two layered extraction approaches on the blast unit body to be built according to caving step pitch, generating a central line of a main layer extraction approach in the Z direction, opening the central line file of the main layer and the upper layer and section patterns of extraction approaches of the blast unit body to be built in a software pattern window, inputting parameter, choosing space objects and operating algorithm to model solidly.

Description

[0001] technical field [0002] The invention belongs to the technical field of computer three-dimensional modeling, and in particular relates to a method for establishing a true three-dimensional model of a blasting unit in mining technology. [0003] Background technique [0004] Since the pillarless segmented caving method was first used in my country in the mid-1960s, it has been rapidly promoted in metal mines, especially in iron mines. This method can be applied to mines where the stability of ore and rock is above medium, and the mining roadway does not require a large amount of support. It has the advantages of simple stope structure, good safety, large production capacity, low degree of mechanization, and high labor efficiency. It is the most important object and means of mining production and mine resource reserve management. The feature of the pillarless segmental caving method is that the ore block is divided into segments, and the entity controlled by the ...
