1 Scope

This part of DZ/T 0276 specifies the determination of rock Shore hardness, abrasion hardness and Mohs hardness. This section applies to rock hardness tests in rock physical and mechanical properties tests. Shore hardness test is suitable for determining the Shore Hard of rock Degree, wear hardness is suitable for the determination of various rock hardness, Mohs hardness is suitable for the simple determination of rock hardness.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Hardness When a rock sample is engraved by another object that is harder than it, its resistance to destructive performance.

3 Shore hardness test

3.1 Principle The Shore hardness test is to use the elastic rebound method to rebound the bump from a certain height onto the surface of the test rock and use the measured The height of the bump back to indicate the hardness. 3.2 Instrumentation 3.2.1 Shore hardness tester, as shown in Figure 1. ......
