width of coal pillar的意思|示意

While the coal seam hardness is definite, the increasing velocity of the width of the plastic zone of pillar decrease with the increase of interfacial bond property between coal seam and roof.

当煤层硬度一定时，随着煤层与顶底板界面粘结性能的提高，煤柱塑性区宽度增长的速度递减；

As the size of coal pillar increases, the width of neutral plane area increases. However, the speeding-up of neutral plane area occupying the width of coal pillar decreases and becomes stable.

随煤柱尺寸增加，中性面区域的宽度逐渐增大，但其占煤柱宽度比例增速降低并逐渐趋于稳定。

The paper introduces a method to use the observation technology to ascertain the width of stage coal pillar by an example.

通过一个实例介绍了用实测技术确定区段煤柱宽度的方法。

The stability of goaf-side roadways depends on not only the abutment distribution, but also the fracturing degree of the coal seam and rock strata alone the pillar width.

一侧采空巷道稳定性不仅与支承压力分布有关，而且与煤体受破坏程度有关。

While the interfacial bond property is unchanged, the width of plastic zone of pillar increases with the increase of buried depth of coal seam.

当煤层顶底板粘结性能一定时，随煤层埋深的增加，煤柱塑性区宽度增加。

The opinion was put forward that the infection of roadway driving and coal mining need considered simultaneously when determination the reasonable width for coal pillar.

提出确定沿空掘巷合理煤柱宽度时，不仅需考虑掘巷扰动影响，还应将本工作面的超前采动影响作为一个重要影响因素。
