Problems solved by technology

[0003] The traditional sampling method of cemented filling body is mainly manual sampling, and the tools used are mostly primitive hand tools such as picks and shovels. The disadvantage of this method is that it will disturb the cemented filling body during the sampling process and destroy its structure. The sample taken out has been damaged and not representative, and it is difficult to reflect the true quality of the cemented filling

specific Embodiment approach

[0022] In order to further illustrate the technical solution of the present invention, in conjunction with the accompanying drawings, the specific implementation of the present invention is as follows:

[0023] The invention discloses a non-destructive sampling method for a cemented filling body. In the method, a wedge-shaped groove 2 is first formed on the surface of the cemented filling body 1, and then a cylindrical sample 3 is taken along the length direction of the wedge-shaped groove 2. The specific steps are as follows:

[0024] (1) if figure 1 and figure 2 As shown, on the surface of the cemented filling body 1 that needs to be sampled, select a suitable position, and cut a wedge-shaped groove 2 with a cutting saw. One wedge surface A of the wedge-shaped groove 2 is perpendicular to the surface of the cemented filling body 1, and the other wedge surface B is oblique Next, the notch width of the wedge-shaped groove 2 is 150mm, the groove depth of the wedge-shaped groo...

Abstract

The invention discloses a water drill nondestructive sampling method of a cemented filling body. The method comprises the steps: firstly, a wedge-shaped groove is formed in the surface of the cemented filling body, then a cylinder sample is taken in the length direction of the wedge-shaped groove, and finally, the cylinder sample is taken out from the bottom of the wedge-shaped groove. The water drill nondestructive sampling method of the cemented filling body adopts a common tool, takes the sample in the surface of the filling body through the simple operation procedures, has the advantages of nondestructive and reliable sampling, good quality and high efficiency, and solves an industry difficult problem in the field.

Description

technical field [0001] The invention belongs to the technical field of filling, and relates to a cemented filling body sampling technology, in particular to a cemented filling body rhinestone non-destructive sampling method. Background technique [0002] The filling mining method is the development direction of mining technology at present, and many domestic mining enterprises have applied the filling mining method or applied the filling technology. The key to ensuring the quality of backfill mining lies in the quality of the cemented backfill body. The quality of the cemented backfill body is the sign of the quality of the cemented backfill body. In order to detect the strength of the cemented backfill body, it is necessary to take samples on the surface of the cemented backfill body that has been formed. [0003] The traditional sampling method of cemented filling body is mainly manual sampling, and the tools used are mostly primitive hand tools such as picks and shovels. ...
