本文介绍了白皎矿区岩体应力场的现场研究。采用孔径应力解除法进行了两个点六个钻孔的空间应力测量。应力测量结果表明，该矿区的应力分布具有三个区域。即顶板内有应力较大区；煤层内有应力最小区；底板区有应力最大区。矿区内岩体应力以近水平构造应力为主。最后进行了一个剖面的线弹性有限元分析研究，在两个实验数据对比的地方反演分析与实测结果基本相符。有限元反演分析勾画出了矿区岩体应力场的整体轮廓。应力场研究结果对矿区地压控制及新水平巷道布置提供了重要依据。 This paper introduces the field research of rock mass stress field in Baijiao mining area. Spatial stress measurement of two holes and six boreholes was carried out by using aperture stress relief method. Stress measurement results show that the stress distribution of the mining area has three areas. That is, there is a large stress in the roof; there is the area with the least stress in the coal seam; and the area with the maximum stress in the floor area. The rock mass stress in the mining area is mainly near the horizontal tectonic stress. Finally, a section of linear elastic finite element analysis was carried out. The inversion results of the two experimental data were in good agreement with the measured results. Finite element inversion analysis delineates the overall contour of stress field in rock mass. The results of stress field provide an important basis for underground pressure control and new horizontal roadway layout in mining area.
