Abstract
BUILDING AUTOMATION SUBSYSTEM "GUARDIAN" TO DETECT EVOLVING VOIDS IN A CAREER Smolyan P.S., Kozikova T.C. Abstract Search void of technogenic and natural character is an urgent task of geophysics. Linked to this is an increasing danger of a catastrophic collapse of the intensive mining both underground and open pit, especially near the abandoned or existing mine workings or quarries. The most significant risk in this case the voids are evolving, that is voids, which change their position in space and size over time. Unfortunately, at the present stage of development of geophysics there is no simple and reliable way to solve the problem of diagnosing the presence and location in space evolving voids. One promising solution to this problem is gravimetric methods. Gravimetric methods are based on the theory of inverse ill-posed problems. These problems usually can be reduced to the solution of integral equations of the first kind with respect to the physical characteristics of the object, in this case the density of the medium. Solution classical gravimetry problem leads to multidimensional integral equations of the first kind for the unknown density function of spatially distributed sources of gravitational anomalies. In turn, the solution of the integral equation for the density distribution with acceptable accuracy for practical purposes, even for a simplified environment is almost an impossible task for modern technology and gravimetric methods, except for special cases. Therefore, the paper proposes a simplified and adapted way to solve this kind of problem. The article gives examples of mathematical modeling of the subsystem "Guardian" to identify evolving voids. Conclusions. 1. Implementation of the subsystem "Guardian" will increase the probability of detecting the presence of voids evolving even in the early stages of their evolution, and to obtain the necessary information for the localization of voids, to determine their quantitative parameters with a high degree of reliability. 2. This information can be used effectively while minimizing the amount of expensive wells of diagnostic for detecting evolving voids.
