崩落

The greatest dangers of pyroclastic avalanches are probably heat and suffocation.

火成碎屑崩落的最大危害可能是炽热和窒息作用。

Because the ore body of Xiaoguanzhuang Iron Mine is soft and broken, which is one of the most difficult deposits to exploit.

实践证明小官庄铁矿无底柱分段崩落法应用大结构参数是可行的。

This paper introduces a production-exploration method for a mine using sublevel caving.

本文介绍一个采用分段崩落法矿山的生产勘探方法。

ABSTRACT Sublevel and block caving are extensively used in mining procedures. The emphasis was focused on the theoretical investigation of ore-drawing over a long period of time.

崩落采矿法是国内外金属矿山广泛应用的采矿方法，而放矿理论长时期是研究的重点，虽然有关的放矿理论很多，但矿岩移动规律还需进一步深入研究。

ABSTRACT Sublevel caving method is a high efficiency mining method for underground mine, it has many advantages, such as a simple mine stope, good work condition, high mechanization and low mining cost. Up to now, this method has been used in more than 85 percent of all underground iron mine.

无底柱分段崩落法是一种高效率的采矿方法，具有采场结构简单，作业条件好，机械化程度高，回采强度大，采矿成本低等优点，迄今应用该采矿方法采出的矿石量约占我国地下铁矿采出矿石总量的85％。

The breakouts began to occur under the depth of 1200m in the main borehole of Chinese Continental Scientific Drilling, 82 breakout images are collected from acoustic borehole televiewer data between 1200m and 2010m.

中国大陆科学钻探主钻孔在1200m深度以下出现了钻孔崩落现象，我们在1200m至2015m的范围内采集了82个钻孔成像测井图象资料。

So maintenance of a perfect and uniform mixed layer in space will help to obtain an effective drawing control.

因此，保持崩落矿岩混杂层空间的完整性和均匀性，有利于获得理想的放矿控制效果。

It is the wheal of Ares that make the great city fall. It is the wield of Ares my great city falls.

玛尔斯的神力令巨墻倒塌，令我的城市崩落。

A Zelkova (chest radius about 60cm) was blown down with rocks in the middle of one road.

一棵胸径约60cm的风倒榉木随土石崩落在路上，在抢修的过程中，部落居民将榉木移在路旁。

A sudden avalanche of dried mung beans (source of the rattle, added as desiccant) bared a fat in-curved leg. The scent of teak lined with camphorwood conjured lotus pools, burning joss sticks, folk dancers' flying silks.

突然崩落的干豆（嘎嘎声的出处，用来做干燥剂）露出一条向内弯的胖腿，麻栗树掺杂著樟树的香味，使人想起莲池，烧香，以及民间舞者飘扬的丝带。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .
