Reasonable Coal Pillar Leaving and Simulation Research in Roadway of Mining Area
摘要
Abstract
Reasonable coal pillar leaving in mining area of roadway is relate to roadway stability and roadway maintenance and normal use. Through theoretical calculations and numerical simulation, the paper analyzes surrounding rock deformation and stress distribution laws of three mining area roadways under different width of coal pillar, achieves the arrangement of 39 mining area, as well as a reason- able width of coal pillar size from the mining area of roadway, which provides reference for arrangement and roadway excavation with similar conditions.关键词
