摘要
根据淮南矿业集团张集矿1410(1)工作面的特殊地质条件,通过FLAC3D数值模拟得出巷道在掘进期间的塑性区、垂直应力、巷道围岩的变形特征。结合现场实测,得出综采工作面沿空掘巷矿压显现的特征。并提出沿空巷道矿压控制措施,以达到综采工作面安全高效回采。
According to the special geological conditions of 1410 （ 1 ） working face in Zhangji mine of Huainan mining industry group, through FLAC3D numerical simulation obtains during tunneling laneway plastic zone, vertical stress and deformation features of roadway surrounding rock. Combines with the field measured, reaches mine pressure appearance characteristics in roadway driving along the goaf of fully mechanized working face. And the mine pressure control measures of roadway along the goaf are put forward, in order to achieve safe and efficient mining in fully mechanized working face.
