深井软岩巷道底臌的数值模拟
Numerical simulation of floor heave of soft rock roadway in deep mine
摘要
Abstract
This paper seeks a solution to the serious floor heave and deformation occurring in-800 level material roadway of 2442 work face in a mine of Long Coal Group Corporation. The study building on roadway engineering geological condition and existing supporting scheme involves developing a method of anchor grouting in roadway floor and analyzing deep soft rock roadway floor heave deformation using numerical FLAC3D . The results show that the novel method could contribute to an obvious reduction in the displacement of floor heave, roof and two-side and range of plastic zone of floor heave, roof and two-side. The field test verifies the validity of the improved supporting scheme-a method capable of a better control of the deformation of the floor heave. The research may provide a reference for soft rock roadway support in deep mines.关键词
