TD 324 A 1008-0562(2015)02-0165-05 Tectonic stress condition of rock burst ZHANG Hongwei, DU Kai, RONG Hai, GAO Yawei College of Mining Engineering, Liaoning Technical University, Fuxin 123000, China Abstract: In order to establish the inner relationship between rock burst hazard and stress field in Daanshan coal mine, this paper utilized the stress measurement results to analyze the types and features of stress field and its relationship with regional tectonic, analyzed the appearance and profile characteristics of Da Hanling exocline and its effect on stress field, and validated the results by using the numerical simulation method. The research results show that the horizontal tectonic stress plays a control role in Daanshan stress field. The stress field is typical tectonic stress field and the maximum principal stress is NW-SE. Da Hanling inverted syncline grows secondary folds——Bai Caotai inverted syncline is a stress concentration region, its stress is 2~ 3 times of South Syn
