Abstract 
Rock physics is the science of the physical and technical properties of rocks, the 
patterns of changes in properties and the principles of their application in the mining 
industry. 
Rock physics is a branch of mining science necessary to determine the methods 
of rock erosion (drilling and blasting, mechanical), the choice of equipment and tools, 
the choice of enrichment methods and equipment for enrichment, as well as ensuring 
the priority of the rock mass. 
All these activities are associated with funds and directly affect the efficient 
operation of mining enterprises. 
From scientists to the development of the science of rock physics: M. M. 
Protodyakonovlar, P. M. Tsimbarevich, T. N. Kuznetsov, N. A. Tsitovich, L. Ch. 
Baron, P. L. Redinder, L. A. Shreiner, V. V. Rzhevsky, T. Da. Novick and others 
have made significant contributions. 
A mineral is a natural rock, the chemical structure and physical properties are 
approximately the same, and it was formed as a result of physicochemical processes 
in the earth's crust. 
Common minerals in the earth's crust: feldspars - 60%, amphiboles and 
pyroxenes - 17%, quartz - 12% and micas - 3.8%.

All rocks are involved in mining. These include bedrock (in situ), overburden, 
sediment, crushed, redeposited or replanted rock. It is necessary to study the 
properties of rocks in their natural state during excavations. In other works (loading, 
transportation, crushing), the fragmented state of rocks is studied. 
Therefore, the following subspecies are included in the rock study: rock mass, 
crushed stone (rock mass) and individual rock fragments (rock sample). 
In mining, individual minerals or rocks are extracted from the entire massif. 
Therefore, rock physics studies the physical properties of minerals and all rocks. 
Rocks are complex aggregates, multiphase (water, oil, gas, etc.). Thus, the 
physics of rocks differs from the physics of solid rocks.
