摘要
通过对急斜特厚煤层水平分段放顶煤开采煤岩移动规律研究,提出了开采过程顶煤和围岩破坏发展分区,即顶煤放出区、沿底座滑区、顶板离层破坏区和煤岩滞后垮落区。分析了影响沿底座滑区和顶板离层破坏区破坏的主要因素及其采动损害传递的主途径。
Through studying the movement laws of surrounding rock of the horizontal section top caving in steep seam.,the failure development division of top coal and surrounding rock caused by mining are presented during the course of caving,namely: top coal caving area,slipping area along the bed rock,roof separation and failure area,delayed caving area of coal and rock etc.The main factors effecting of slipping area along the bed rock and roof separation and failure area and the major avenue of damage surrounding rock caused by mining are analyzed in this paper.
