【Abstract】 This paper mainly introduces the method,the procedure and the result of the in situ stress measurement of Yanbei coal mine. Through the field measurement, the in situ stress’s value and orientation of the 4 stations in 2 levels were gotten. And by regression analysis, the in situ stress field’s regularities of distributions of the mining area was also gotten. The measurement result has great significance to the coal mine’s producing and building.更多还原
