Rock mass classification systems are used for various engineering design and stability analysis.
If clay rocks with admixtures of other species,then plastic deformation occurs when additional pressure on the rock mass.
Loading of the rock mass in the preparatory workings can be made coal- and rock-loading machines or manually.
Enabling better engineering judgement and more effective communication on a project.provide a basis for understanding the characteristics of each rock mass.
The rock mass contains not only coal, but also non-combustibles- rock that can reach up to half of the extracted resource.

The first rock mass classification system in geotechnical engineering was proposed in 1946 for tunnels with steel set support.

They occur when rock masses that make up the mountain slopes lose foundation due to the disruption of rock balance.
Using through tacheometric shooting build the lower edge of the ledge with the purpose of increase of accuracy for furthercalculations(for example for the calculation of the volumes of excavated rock mass) must be removed and rebuild the upper edge.
Empirical, i.e. rock mass classification, methods are extensively used for feasibility and pre-design studies, and often also for the final design.
Nowadays the classification system itself is not very often used, but the determination of the RQD as index for rock core quality is standard practice in any geotechnical rock drilling, and is used in many,more recent, rock mass classification systems, such as RMR and Q-system(see above).
The very emergence of the rock mass Peterman caused a lot of controversy, speculation and controversy, since the middle of the mountain appeared almost endless and flat desert.
The Rock Structure Rating systemis a quantitative method for describing quality of a rock mass and appropriate ground support, in particular, for steel-rib support, developed by Wickham, Tiedemann and Skinner in the 1970s.
Method of seismic diagnostics of geodynamic state of rock mass in the zone of production working"(Patent No. 43364) is designed to determine the state of rock mass over production working during development of coal seams in conditions of possible occurrence of dangerous geodynamic phenomena(sudden coal and gas outbursts, pressure bursts, large caving of the main roof, etc.);

However, the major disturbance to the rock mass and groundwater by the use of nuclear explosions, as well as arms control considerations, has led to the general rejection of this option.
These are based on empirical relations between rock mass parameters and engineering applications, such as tunnels, slopes, foundations, and excavatability.
