| 摘 要： | 通过数值计算分析，研究了综放沿空掘巷围岩变形及窄煤柱的稳定性与煤柱宽度、煤层力学性质及锚杆支护强度之间的关系，提出一个新观点，即高强度锚杆支护的窄煤柱是沿空掘巷围岩承载结构中的一个重要组成部分，并针对不同煤层条件确定了相应的窄煤柱合理宽度，并将研究结果成功地应用于工程实践。

| Abstract: | Through numerical calculation and analysis,the relationship among the stability of narrow coal pillar,the rock deformation of roadway driving along next goaf in fully mechanized caving face,the strength of bolt support,the mechanical property of coal seam and the pillar width is studied. It is proposed that the narrow coal pillar supported by high-strength bolts is an important component in the rock bearing structure of roadway driving along next goaf,and according to various conditions of the coal seams,the rational width of the corresponding narrow coal pillar is determined. The research results have been successfully applied to engineering practice . |
