摘要：

An electromagnetic radiation evaluation method for the relative stress state of coal bed under stress was proposed in this paper. The stress distribution of mine roadway or working face, as well as high stress zone or stress gradient zone, was analyzed by the method. The main advantages of the technique are its characteristics of non-contact, orientability, and regional monitoring. Correlation analysis of electromagnetic radiation with relative stress was carried out in coal mines and tunnels. The results indicate that the electromagnetic radiation technology has a wide application prospect in the evaluation of mine pressure. (C) 2011 Elsevier B.V. All rights reserved.
