Mining and pillar width analysis of stripe mining under buildings 建筑物下条带开采采留宽度分析
2.
The settlement of the reasonable coal - pillar width in the short - wall mining 短壁开采合理煤柱宽度的确定
3.
The study and apply of the coal pillar width parameter in along stull tunnel 沿空巷道煤柱宽度参数的研究与应用
4.
The study indicates that with the increase of the coal pillar width the peak mining stress delays its appearance and the increase of the displacement and stress are not synchronous 研究表明，综放沿空留巷受采场矿压影响时间和程度随留巷煤柱宽度的增加表现出明显带后现象以及位移和压力增长的不同步现象。
