Abstract:
Development of engineering-geological processes, including dangerous, within the boundaries of the area of active influence of mining operations in the undeground minings (tunnels, preparatory face or working face) at the massif of mountain rocks, is due to, as is well known, changing in structure and parameters stress-strain state (SSTS).
Estimation of stresses in the near zone of exposures of the massif (within the first meters) is carried out by a number of instrumental methods, regulated by federal or departmental documents for those or other engineering and geological conditions and technologies for mining (pressure installations, disking of core, extraction of rubbles, etc.). Widely known and experimental analytical methods based on stress calculations in the neighborhood of working area from known (measured) initial stresses on the exposures of the massif.
A significant advance in the development of the experimental and analytical approach to the organization of continuous monitoring and forecasting the development of hazardous engineering and geological processes in underground construction is the improvement of seismic methods of remote evaluation of the structure and parameters of SSTS [1, 6, 12, 13]. It should be noted that at present several regulatory documents on the forecast of dynamic phenomena and monitoring of rock mass during mining of coal deposits, as well as the state of the mine atmosphere in the excavations and which regulate, among other things, the use of seismic monitoring systems [2, 3, 4]. Similar documents in departmental formats are also applicable to the conditions of construction of transport tunnels, hydroconstructions and other objects of increased responsibility.
The article proposes an approach to the creation of a geoinformation safety panel of underground mining works based on related solutions in prognosis of the development of stressed state of the massif of mountain rocks and gas flows within the framework of the Fidesis strength analysis package.
