摘要
程潮铁矿东主井区工业场地不稳定的成因，过去认为是地下采矿引起的地表塌陷错动波及到场区而引起，根据矿体上部和上下盘围岩工程地质调查和东主井场区地表和地层内部位移观测资料，提出陡倾结构面张开说，即认为场区不稳定的直接成因是地形、地基及岩体内部陡倾结构面的开裂。
Ground surface subsidence and dislocation caused by underground mining is believed as the cause of instability at eastern main shaft field in Chengchao Iron Mine in the past. According to geological surveying of surrounding rock and displacement monitoring of inner strata, a theory of steep - inclined structural planes opening is put forward in this paper. That is to say, the direct causes of field instability are terrain, ground base and the opening of steep - inclined structural planes.
