根据地质调查和地表岩移测试资料分析了通钢板石沟铁矿上青矿区岩移规律 ,得出了矿体上盘围岩渐进崩落和位移过程受断层控制的结论。虽然受岩移的影响目前的陷落角小于设计的陷落角 ;但由于断层出露位置已较准确控制 ,所以西风井的稳定状态不会受到影响。根据井下收敛观测和地压调查的结果 ,提出了减小地压活动的对策
According to the geological survey and the data of the surface rock displacement test, the rock movement law of the Shangqing mining area in the Tongshen iron orefield is analyzed, and the conclusion is drawn that the surrounding rock of the ore body is gradually caving and the displacement process is controlled by the fault. Although the current collapse angle is less than the designed collapse angle due to the effect of rock movement, the steady state of the westerly wind will not be affected due to the more accurate control of the fault exposure location. According to the results of downhole convergence observation and ground pressure survey, some countermeasures to reduce the ground pressure are put forward
