新城金矿地应力场测量采用应力解除法和实现完全温度补偿的空心包体应变测量技术。为了提高测量结果的可靠性和精度,在现场测量和结果计算、分析过程中,采用了完全温度补偿技术,自动应变测量和记录系统,用双迭代程序求测点岩石弹性模量、泊松比和测点k系数、地应力值等一系列新理论、新技术.现场实测获得矿区4个水平、 17个测点的三维应力状态,并根据实测结果对矿区地应力场的分布规律进行了详细分析,建立了矿区地应力场分布模型。
Stress measurement in Xincheng gold deposit adopts stress relieving method and hollow inclusion strain measurement technology to achieve complete temperature compensation. In order to improve the reliability and accuracy of measurement results, a complete temperature compensation technique and automatic strain measurement and recording system were adopted in the field measurement and calculation and analysis of the results. The iteration program was used to determine the elastic modulus of rock mass, the Poisson’s ratio And measuring point k coefficient, the value of stress and a series of new theories and new technologies. According to the measured results, the distribution of ground stress field in mining area was analyzed in detail, and the distribution model of ground stress field in mining area was established.
