PROJECT ESSENCE: The developed method allows to define the rational kinematic and force parameters fixing sections providing effective communication with side rock masses and necessary strength values in different geological conditions. The development is aimed at the solution of the increasing coal mining due to a significant increase of load on the sewage treatment facility. The total number of sewage facilities can be reduced regardless geological conditions of the mining company.
ECONOMIC EFFECT:
The development allowed to reduce coal mining cost due to:
- Increasing load on the sewage facilities in 1,5 - 2,5 times in comparison with existing technologies;
- Reducing of the total number of sewage facilities in 1,5 - 2 times;
- Increasing of labor productivity and reducing number of employed workers in mining works in 1,5 - 1,8 times.
