摘要
根据3．5～10m大倾角煤层巷柱式放顶煤开采巷道布置方式，建立顶煤体力学模型。采用弹塑性理论分析和FLAC^3D数值模拟相结合的研究方法，确定了该采煤方法合理的阶段高度。
A mechanics model of top coal is built up according to the roadway layout manner of roadway caving mining in 3.5 ～ 10m deeply inclined coat seam and the rational stage height of this mining method is confirmed by a combined method of elastic-plastic theory analysis and FLAC^3D numerical simulation.
