摘要

提出了在不破坏试样的情况下测定材料强度的方法。该方法的实质是通过压入变截面压头来确定岩石的强度特性。其实际意义在于可以对小尺寸样品(3mm或更大)进行岩石强度的快速分析,例如,在钻井时使用不稳定层段的滑坡岩屑颗粒;不需要制备标准物质;所用设备的简单性和可用性以及所得结果的高准确性也很重要。所开发的方法没有类似物,并在白俄罗斯共和国和俄罗斯联邦的专利局获得专利。

On the Use of Indentation for Studying Rock Properties
It was developed the method for determining the strength of material without breaking the test sample. The essence of the method is to determine the strength characteristics of the rock by pressing into the variable cross-section indenter. The practical significance lies in the possibility of performing an express analysis of the strength of rocks on small-sized samples - 3 mm or more, for example, using the particles of landslide cuttings from unstable intervals when drilling wells; there is no need for the preparation of reference material; the simplicity and availability of the equipment used and high accuracy of the results obtained is also important. The developed method has no analogues and is patented in the patent offices of the Republic of Belarus and the Russian Federation.
