Problems solved by technology

Since it is impossible to set up a laboratory-like marking boundary in on-site blasting and collapsing, in general, only the amount of ore released on site and the detection of ore grade can be used to control the ore-drawing process. On-site ore-drawing and laboratory simulation of the ore-drawing process Only indirect comparisons can be made

Embodiment 1

[0012] Such as figure 2 shown. In the caving mining method, a dye pack 1 is placed at the bottom of the blast hole 2 at the top of the ore body to form a dyeing interface for blasting ore at the top.

Embodiment 2

[0014] When adopting the caving method to mine a blind ore body with stable surrounding rocks, it is necessary to use forced caving to form a cushion layer of waste rock 5 . Generally, fan-shaped medium-deep hole blasting is used in the surrounding rock before the mine collapses. At this time, the dye package can be placed in the position close to the hole in the caving blast hole or in the lower horizontal blast hole 2 near the caving rock mass. After blasting, these dyed ores or rocks can be blasted ore 4 The dyed interface 6 of the loose body forms a specific interface sign of the exploded body, and provides information on the rocks that first arrive at the ore-drawing mouth for subsequent ore-drawing operations.

Embodiment 3

[0016] In mining production blasting (not limited to caving mining method), different color dye packs can be set in appropriate positions in the blasting boundary blastholes of different blasting units. Provide direct evidence. For example, whether it is underexcavated or overexcavated, the situation of large blocks formed by non-blasting factors, etc. It can enrich the information of blasting effect observation and statistics.

Abstract

The invention relates to a method for dyeing an interface of a bursting body. In the method, a container filled with dye of a certain color is placed on the bottom of a blast hole to be burst; when the blast hole of a dye bag is burst, the container can be cracked under the action of the burst pressure of an explosive and release the dye, the dye can dye ores or rocks near the bottom of the blasthole, and then the dyed ores or rocks become dyeing interfaces of bursting ore loosing bodies. By using the method, a specific interface mark of a burst body can be formed, which can provide the change information of the interfaces of the burst ores and rocks of an underground mine in a closed space, can provide a new means for ore drawing control management and research in a stope caving method of the underground mine, and also provide a new evidence for bursting effect analysis.

Description

technical field [0001] The invention relates to a blasting body interface dyeing method, which is a method for dyeing the ore or rock loose body interface produced after engineering blasting. Background technique [0002] The motivation of the present invention comes from the ore-drawing management of the caving method in mining production. The caving method is a mining method with high mining strength, low cost and safe operation. But the disadvantage is that the ore collapsed in the stope is directly in contact with the upper waste rock, and the ore is released in the state of overlying rock. Therefore, in the process of mining, it is easy for the upper part of the caving waste rock to infiltrate into the ore, resulting in the loss of the released ore or the deterioration of the dilution index. [0003] In mining, the management of ore drawing under the overlying rock generally adopts experience or laboratory simulation research results to formulate the ore drawing plan,...
