Rio Tinto is Spanish,which means yellow river.In 1954 ,the company sold most of the Spanish business.From 1962 to 1997,the company merged with a number of influential global mining companies,and in 2000 the successful acquisition of the North Australian mining companies have become in the exploration,mining and processing mineral resources ,the global leader.

Rio Tinto是西班牙文，意为黄色的河流。1954年，公司出售了大部分西班牙业务。1962年至1997年，该公司兼并了数家全球有影响力的矿业公司，并在2000年成功收购了澳大利亚北方矿业公司，成为在勘探、开采和加工矿产资源方面的全球佼佼者。

The results show that the ranges of secondary stress distribution have differences corresponding to different wall rock conditions of mining tunnel; but the principal stress distribution transits from compressive stress centralized in mining tunnel sidewall to tensile stress centralized in mining tunnel vault and floor.

研究结果表明，围岩条件不同的采矿巷道其二次应力分布影响范围有所差异，但围岩主应力总体上表现为由巷道边墙中下部位的压应力集中带逐步过渡到拱顶、底板一定范围内的拉应力集中带。

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。

Special mining engineering includes hydraulic mining technology, three underground mining technology, and underground coal gasification.

特殊开采工程包括水力开采技术、&三下&矿体开采技术、地下气化技术等。

Today the Trinities still bear the scars of extensive gold mining operations, ranging from placer mining that rerouted river and stream beds to a scattering of abandoned mining tunnels, some of which were operated into the 1930s.

今天，特里尼迪山上淘金留下的创伤依然无处不在，从河流和河床的改道，到无处不在的废弃金矿。有些金矿一直开采到20世纪30年代。

Today the Trinities still bear the scars of extensive gold mining operations, ranging from placer mining that rerouted river and stream beds to a scattering of abandoned mining tunnels, some of which were operated into the 1930s.

直至现在我们还能看见采金给这片地方带来的伤痕，对藏金地的大面积的搜索留下了许多废弃的矿井，变更河床以及溪床的水流路线而注入其中，它们有些开槽于19世纪30年代。

Today the Trinities still bear the scars of extensive gold mining operations, ranging from placer mining that rerouted river and stream beds to a scattering of abandoned mining tunnels, some of which were operated into the 1930s.

直到现在特里尼特斯还饱受修砌挖金矿井时带来的创伤。从改变河流河床的采砂矿到分布在不同地方的废弃了的挖矿隧道，其中有些隧道还是20世纪30年代才挖的。

To settle the traditional conflict between aquifer protective mining, and to enhance the coal recovery ratio to the maximum, based on the protection mining technique in longwall coalface with rapid mining.

为解决浅埋煤层保水与采煤这一矛盾，并最大限度的提高煤炭资源回收率，神东矿区上湾煤矿51201大采高长壁综采工作面进行了保水开采工业性试验。

Take the 51201 big mining height coalface in Shangwan coal mine and the 32201 coalface in Bulianta coal mine as prototypes, the development processes of the overlying strata for these two types shallow coal face with big mining height are simulate, as the mining space increase.

分别以上湾煤矿的51201工作面和补连塔32201工作面为原型，模拟了随开采空间变化，这两类浅埋煤层大采高长壁工作面的采动覆岩导水通道的发育过程。
