Abstract

Abstract:

Abstract:In order to improve the transportation system of Lugou mine,The -15m level transportation roadway has to be reconstructed.After comparing the two schemes,one of which was adopted as retaining the old roadway while excavating a new one along the old entry.Than filled the old roadway. The laws of stress distribution and displacement of surrounding rock evolution was obtained with the application of FLAC3D numerical simulation software. After reconstruction,the deformation of surrounding rock was small.Which verified the rationality of reconstruction scheme design and construction process.It provides reference experiences for people of roadway reconstruction without stoping production under similar geological conditions.

Key words: Keywords: Lugou mine, reconstruction scheme, numerical simulation, roadway repair
