| 摘 要： | 条带煤柱稳定性决定着巷道的维护状况,通过对条带两帮煤体受力特点的分析研究,分析了各相关因素对煤体破裂区和塑性区宽度的影响.破裂区宽度及其演化发展是影响煤柱稳定的主要因素,强化煤柱破裂区的强度,阻止塑性区向破裂区的演化,是提高煤柱稳定性的重要途径.针对煤柱的特定赋存条件和影响煤柱稳定的众多因素,有针对性的展开支护设计,合理确定煤柱宽度,有利于提高煤炭资源回收率.

| Abstract: | The maintenance conditions of the mining gateway were dependent on the stability of the strip coal pillar. With the analysis and research on the stressed features of the coal mass along the two sides of the strip, the paper analyzed the influences of each related factors to the width of the coal mass breaking zone and plastic zone. The breaking zone width and the evolution development were the main factors influenced to the stability of the coal pillar. To intensify the strength of the breaking zone in the ... |
