【摘要】 针对程潮铁矿东主井附近岩层错动角超出设计范围的实际情况,首先采用现场调查、地表移动监测手段进行东区地表塌陷规律的分析,其次采用岩层深部变形观测、调查分析和FLAC数值模拟手段进行东主井地表变形破坏机理的研究。研究表明,东主井附近地表开裂破坏的直接原因是滑坡引起的,实际的错动角为63.0°。更多还原

【Abstract】 In view of the fact that the displacement of the rock stratum near the main east shaft in Chengchao Iron Mine was beyond the design range,an analysis of the subsidense law of the ground in the east district was made by means of site investigation and surface displacement monitoring.Then,the surface deformation mechansim of the main east shaft was studied by the observation investigation and analysis of the deformation at depth in the rock stratum and by FLAC numerical simulation.The study indicated that the driect cause for the cracking failure in the ground surface near the shaft was slope slipping and the actual displacement angle was 63.0°.更多还原
