It was shown that coal seam floor failure depth of working face 2121 was 32.5 to 5 m, approximately three times as deep as that of shallow working face(in genera l,9.15 to 12.0 m). Coal seam floor failure depth increased with mining depth. Potential risk of water inrush through coal seam floor of working face 2121 is much higher for deep mining than for shallow mining.

试验结果表明：该工作面底板破坏深度为32.5~35 m，比300 m采深以内的工作面实测深度(9.15~ 12.0 m)增加2倍以上，说明随着开采深度的增加，煤层底板采动破坏深度呈明显增大的趋势，因此，在水压和破坏深度二者同时增加的条件下，2121工作面深部煤层开采的突水危险性远远大于浅部煤层。

Any of various parrots of the genera Ara and Anodorhynchus of Central and South America, including the largest parrots and characterized by long saber-shaped tails, curved powerful bills, and usually brilliant plumage.

More than 90% of Permian genera ofsponges, corals and brachiopods vanished in the extinction.

Rather than counting individual species of fossils, which vary over time, palaeontologists who study extinction usually count entire groups of related species, called genera.

古生物学家研究生物灭绝通常计算整个有亲缘关系的物种种群化石，而不是计算物种个体化石，因为物种的个体化石会随时间不断变化。

Is this factor responsible for the greater part of biodiversity How does evolution produce enormously species-rich genera, such as Eucalyptus, many of which can coexist happily in the same habitat I hope that this anniversary will result in a new impetus for field-based biology and palaeontology to answer such questions.

这一因素是造成生物多样性的较大部分的原因吗？进化如何非常多地生成物种丰富的属，例如桉树，其中许多能够愉快地和平共处在同一生境？我希望这一次的周年纪念将为野外生物学和古生物学造成新的推动力来回答这样的问题。

Cygnoides , species which are so different that they are generally ranked in distinct genera, have often bred in this country with either pure parent, and in one single instance they have bred inter se.
