Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention will be further described.

[0022] A method for delineating an ore body using large holes, comprising the following steps:

[0023] Make geological records of the bottom structure of the stope, and form the lower horizontal secondary delineation plan;

[0024] It is characterized in that it also includes the following steps:

[0025] The rock-drilling chambers in the upper part of the stope are cataloged, and after the upper part is cataloged, the plane of the upper rock-drilling chambers is formed to form a second delineation plan of the upper level;

[0026] According to the position of the stope on the geological plan of the middle section, use the geological profile of the ore body to draw the geological profile of the stope. If the geological profile line is within the range of the stope, use the geological profile of the ore body modified according to the recorded data as the The geological p...

Abstract

The invention discloses a method for delineating an ore body by using large holes, which comprises the following steps: carrying out geological cataloging on the bottom structure of the stope to form a lower level secondary delineation plan; it is characterized in that it also includes the following steps: The rock-drilling chamber is cataloged, and after the upper catalog is sorted out, the upper-level secondary delineation plan is formed on the upper rock-drilling chamber plane; according to the position of the stope on the geological plan of the middle section, the stope is drawn using the ore body geological profile Geological profile, if the geological profile line is within the range of the stope, use the geological profile of the ore body modified according to the recorded data as the geological profile of the stope; provide the geological plan and geological profile to the mining technicians, the geological The technicians assist the mining technicians in the design of the large hole layout; the geologists select two to three large hole alignment sections within the stope area according to the large hole layout design, and track the construction status of the large hole on the line.

Description

technical field [0001] The invention relates to a method for delineating an ore body by using a large hole. Background technique [0002] The prior art utilizes the delineation method of the stope ore body of large-hole mining to be: 1, the bottom structure of the stope, such as the cutting ditch, the ore approach road, is carried out to geological record, and the rock drilling chamber on the stope top is recorded simultaneously, After the original catalog has been sorted out, the bottom structure plan of the stope and the ore body and geological boundaries in the upper rock drilling plan plan are revised accordingly to form a second delineation plan of the stope; 2. According to the stope on the middle geological plan location, use the ore body geological profile to draw the stope geological profile; if the geological profile line is within the range of the stope, the ore body geological profile modified according to the recorded data can be used as the stope geological pro...
