Sistaining mining in whole different rigidity
- Authors:

Studies conducted in the mines «Rostovugol», showed that, for assessing the sustainability of preparatory excavations in the management of sewage treatment works is enough to determine the allowable values of convergence of the roof and ground-level workings and potential energy of elastic deformation of the pillars. These indicators can be used in the coal mines of other basins.

Prediction of dynamic manifestations of rock pressure in the all over automated longwalls
- Authors:

The support control system «MARCO» has programs for the estimation of a geomechanical situation around the face by continuous measurements of pressure in the legs of support. The analysis of the face convergence allows to predict the possibility of a rock burst. The seam’s reaction on the shearer or plough influence may be the dangerous main roof collapse into the mine-out space of longwall.

The analyses of influence of goafs on the state of developmental excavations as applies to Starobinsky potassium salt deposit
- Authors:
- A. P. Gospodarikov
