It was in 1914 that garnet find was reported in the desert-savanna are of Western Sahara desert but was forgotten away because garnet was not considered valuable due to extremly low gemmy content.

就在和塞内加尔、蒙罗维亚交界处。其实当地石榴石开采从据当时80年前的1914年就开始了，只是因为都是出产一些大的不透明或只有部分透明的晶体而逐渐被大家淡忘。

The Da＇anshan coal mine already entered the deep mining stage, Geologic structure is complex by the fold geologic structure primarily in the Minefield, the mining coal working surface and the tunnel impact geostatic pressure occurs frequently, but so far has not conducted the system research.

大安山煤矿现已进入深部开采阶段，井田内以褶曲为主的地质构造复杂，采煤工作面和巷道冲击地压发生频繁，但到目前为止还没有进行过系统研究。

Examples might be in geology and geotechnics, information technology and software development, mining, biomedical technology, optical communications, renewable energy systems, agriculture, and so on.

例如在地质学，地址技术，信息科学与软件发展，开采，生物科技，光纤通讯，可持续能源系统，农业。

In order to study the rock mass stress in coal district,a regional geotectonic model is established by using the geology dynamic division.

0引言对矿山开采而言，地应力是诸多采矿工程稳定性影响因素中最重要和最根本的因素之一[1]。

Deep coal mines are under the complex mining environment conditions of high in-situ pressure and geotherm, as well as high methane content in coalbed and pore pressure dissipation.
