Abstract
The electromagnetic radiation signals associated with the destruction of rock samples were studied under field and laboratory conditions. The parameters of the signal were found that preceded the violation of the integrity of the rock in laboratory studies. It is shown that the highest efficiency of the method of electromagnetic radiation is achieved when predicting the dynamic manifestations of rock pressure in the form of rock shock.
Highlights
In the works [1,2,3,4,5,6,7,8] it was shown that the destruction of a rock is accompanied by electromagnetic radiation
This paper presents a laboratory analysis of the electromagnetic radiation (EMI) signals of the host rock from the S.M
Field studies were carried out using the Angel-M mine equipment [10] and the REMI-3 registration and diagnostic complex [4]
Summary
In the works [1,2,3,4,5,6,7,8] it was shown that the destruction of a rock is accompanied by electromagnetic radiation. The nature of this radiation is not fully understood. In the works [5,6,7,8] the process of destruction of rocks, accompanied by four stages of destruction, is considered. At the third stage of destruction, a discontinuity of the rock and an avalanche-like destruction are observed. The recommendations for the development of the architecture of the registration and diagnostic complex REMI, which includes software and an electromagnetic radiation recorder with a graphic display, are given
