Abstract
The article analyzes the methods and tools for predicting the impact hazard in the conditions of underground mining of gold deposits. To assess the stress state of a rock mass, the core disking method is proposed as a basic method. The degree and categories of impact hazard of sections of the rock mass are estimated. Due to the impossibility of solving many problems by geomechanical only field studies. The reliable efficiency of the use of the finite element method and the boundary element method in predicting the impact hazard of the field sites a priori is shown.
Highlights
The difficulties, associated with the research of rock pressure, caused by the fact that the results of the research in a mine or in a certain mine are very specific to the location, where the research is carried out, which means that the results usually do not have a trend to be generalized and sometimes may be contrary to the results of other studies
In order to study the rock pressure, monitoring and measuring must be provided in real underground conditions, in the laboratory
These observations usually are provided in very different conditions, on different species and at different depths
Summary
The difficulties, associated with the research of rock pressure, caused by the fact that the results of the research in a mine or in a certain mine are very specific to the location, where the research is carried out, which means that the results usually do not have a trend to be generalized and sometimes may be contrary to the results of other studies. In order to study the rock pressure, monitoring and measuring must be provided in real underground conditions, in the laboratory. These observations usually are provided in very different conditions, on different species and at different depths. The problem of creating a safe environment for developers (miners), where rock formations were exposed to shock waves, possible through an integrated consideration of all the issues from the field of exploration, type of mining, methods of preparations and development schemes, transportation, and with the organization of labour at the facility
