Abstract The paper introduced the principle of management of weak energy blasting for rock burst treatment， taken the Jinping hydropower station diversion tunnel as background engineering，the distribution of high stress was simulated by FLAC3D dydropower，the stress release sites were confirmed adopting Russenses rock burst discriminating method，four kinds of stress release blasting scheme were drafted，conducted three groups of blasting test for each scheme，the test results are analyzed. Experiments show that the weak energy blasting can release high ground stress and achieve the goal of controlling rock burst through careful control of the explosion energy. But the method is only to process the stress to the deep rock，do not eliminate stress，so timely supporting measures should be indispensable.

Key words： tunnelling engineering weak energy blasting rock burst Jinping hydropower station
