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,...
