Two approaches are considerable in the construction of the classification of rocks by their rippability (processing properties).

1. The energetic approach includes:

- evaluation of the power-consuming of two foregoing physical processes on the whole technological chain of extraction and processing of mineral resources:

- summation of the power-consuming and obtaining the integral energy intensity.

Rocks could be classificated by their rippability according to the numerical value of the integral energy intensity.

2. The criteria approach.

This approach edds up to the obtaining of the infinite criteria on the whole technological chain of extraction and processing of mineral resources and their following multiplication. Rocks could be classificated by their rippability according to the numerical value of the obtained product.

The construction of the rippability classification of various rocks allows to chose the optimum alternative of the extraction and processing technology of mineral resources. Choosing of the optimum alternative happens on the projecting stage.

The methodology of the construction of classification supposes the knowledge or getting the analytical forms for the description of the technological processes. By-turn, this sets the problem in front of the mining science. This problem is connected with the replenishment of the knowledge arsenal in the area of the analytical description of rocks` properties interconnection and the processes of the anthropogenic impact on them, including the creation of the innovative technologies of extraction and processing of mineral raw materials.
