沿淮矿区,在工程施工中,由于对现代地应力场的研究处于初始阶段,且缺乏现代地应力测试技术。该区在现代应力场作用下,井巷工程稳定性破坏直接损失达千万元以上。因此,本文通过震源机制解,邻区的绝对地应力量测岩石圈层的构造应力与地幔对流情况,并结合遥感影象的共轭线性体构造的主应力轴方位解技术方法,较全面地分析、预测了该区的现代应力场特征。该区现代构造应力场最大主压应力方位在N30°—60°E范围之内。它是沿淮矿区井巷工程稳定性严重破坏的重要因素之一,而且是第一性的。
Along the Huaihua mining area, in the construction of the project, the research of modern geostress field is in the initial stage, and the modern geostress testing technology is lacking. Under the action of modern stress field, the stability damage of the shaft and tunnel project directly damages over 10 million yuan. Therefore, in this paper, by means of focal mechanism solution, the absolute stress in the adjacent area measures the tectonic stress of the lithosphere and the convection of the mantle, combined with the principle of azimuth resolution of the principal stress axis of the conjugate linear body in the remote sensing image, Analyzed and predicted the characteristics of modern stress field in this area. The maximum principal compressive stress of the modern tectonic stress field in this area is in the range of N30 ° -60 ° E. It is one of the important factors of the serious damage to the stability of the shaft and culvert along the Huaihua Mine and it is also of primary importance.
