Study on Geostress Measurement and Distribution Law of Dynamic Phenomenon Frequently Occurred in Mining Area
Abstract：In order to analyze the dynamic phenomenon frequently occurred of Luliang Mining Area, the theoretical analysis and the site measurement method were applied to the study on the mine underground stress measurement and distribution law. The hollow inclusion type stress releasing method was applied to the measurement of the in-situ rock stress. The ground stress distribution law of the mining are- a was obtained and the correlation of the ground stress and dynamic phenomenon frequently occurred was analyzed and studied. The results showed that the ground stress field of Ltiliang Mining Area was mainly as the horizontal structural stress and the horizontal stress influence had a remarkable orientation. The max azimuth angle of the horizontal stress was concentrated between 96. 96°- 109. 11° and had a high axial included angle to the gateway of the coal mining face. The max azimuth angle was 77. 85° in average and was the reason to cause the dynamic disaster frequently.
