The invention discloses a construction method for microseisms monitoring and stress relieving of a strong rockburst tunnel. The construction method comprises the steps that firstly, a microseisms monitoring system is installed, and microseisms monitoring and rockburst predicting are performed; secondly, specific positions where rockburst possibly happens, the scale and the intensity of the rockburst are obtained through the microseisms monitoring system; thirdly, a stress relieving hole is drilled through a drilling jig; fourthly, an explosive is loaded and detonated; fifthly, the treatment of danger eliminating, water spraying and dust falling are performed, and slag is discharged; sixthly, primary concrete spraying is performed on a working face; seventhly, shell-expansion type prestress hollow grouting anchor rods are arranged systematically; eighthly, a reinforcing rib mesh is arranged in a laying mode, and concrete is sprayed again. The construction method for microseisms monitoring and stress relieving of the strong rockburst tunnel overcomes the defects that in a traditional stress releasing process, drilling and explosion are blind and a stress releasing effect is poor. According to the construction method for microseisms monitoring and stress relieving of the strong rockburst tunnel, prediction of a stress concentrating portion is accurate, stress releasing is in place, a detecting result of a releasing effect is reliable, rockburst prevention pertinence is strong, and the construction method for microseisms monitoring and stress relieving of the strong rockburst tunnel is simple, practical, strong in operability and good in effect.
