摘要：

An electromagnetic radiation (EMR) method associated with rock fracture was employed to study water infusion in rockburst-prone coal strata. Measurements of EMR activity during borehole drilling revealed that a hole nearing a stress peak excites a sharp increase in EMR activity. Water pressure increase/decrease excited EMR activity up to the coal stratum transition to residual stress. An absence of EMR activity during water pressure changes could be a criterion for water infusion performance. (C) 2000 Elsevier Science B.V. All rights reserved.
