A mathematical model is obtained in the form of a differential equation of mass transfer, which takes into account the physic and mechanical composition of the dust emission from the ventilation shaft of the coal mine as a factor of ecological hazard.
At the same time, one of the factors that determine the environmental hazard of the coal mine operation is the physic and mechanical composition of the dust emission into the atmosphere from its main ventilation shaft [17, 18].
This is consistent with the results obtained on the mathematical model in the form of a differential equation of mass transfer, which takes into account the physic and mechanical composition of the dust emission from the ventilation shaft of the coal mine as a factor of environmental hazard.

Generally, it is associated with many factors of welds [6-9].
The mechanical properties of the used steel are: tensile strength 915.73MPa, yield strength 585.8MPa, fatigue strength 560MPa and total elongation 17.5%.
The interplay of mechanical properties and microstructures at HAZ explains the low fatigue strength in the weld after RSW.

Table 2 AUGMENTED TEST SYSTEMS Discussion of some properties of the estimation The performance of the input estimation is dependent on several influence factors, which shall be closer looked at. 1) Parametrization of the covariance matrix A major influence on the estimation result arises from the parameterization of the covariance matrix.
While the ideal system covariance tuning factor depends on the actual model quality, especially the effect of the input covariance factor is important to adapt the estimation result to the ndividual requirements.
In comparison, a 10% error in the damping of the eigenmode hardly affects the estimation.

It was found that additional contact areas due to pile-ups have a significant effect on determination of mechanical properties by the nanoindenter.
Introduction Nanoindentation tests are commonly used for studying the mechanical properties of materials at a very small scale.
It was shown that the Oliver-Pharr approach for determining mechanical properties leads to either an overestimation or underestimation of the calculated values for elastic modulus and hardness [[] A.
Furthermore, it has been pointed out that the pile-up and the sink-in behavior are dependent on other mechanical properties of the material as well as its processing history [[] Y.
The major factors affecting the pile-up and/or sink-in are the work hardening rate, the ratio of the elastic modulus to yield strength (E/σy), and the ratio of contact depth to the maximum depth of indentation (hc/hmax).

Characterization of the properties of such material requires two parameters; one associated with energy storage, and one, with energy dissipation.
