中国铝矿集中在那几个省市

铝矿分布如图所示 :
山西占42%,贵州占17%,河南占17%,广西占15%,山东占3%,还有6%分布在其他小位置.
再详细我就不知道了

北方地区主要的矿产资源及其所在地

北方主要矿产资源是煤 铁 石油

诚求高人将下面文章翻译成英文的,不要谷歌直接翻译的,先谢谢了!在我国尾矿库的重大事故时有发生.安徽黄梅山铁矿尾矿坝1986年4月30日发生溃坝,造成19人死亡,受伤100人,河南滦川县赤土店乡

In our major accidents occur frequently tailings. Anhui HuangMeiShan iron ore tailings DAMS on April 30, 1986, killing happened dam 19 deaths, wounded 100 people, henan luanhe river county red soil shop township molybdenum May 24, 1992 when repairs in massive tailings row hongtong collapsed, killing 12 people died in fujian province in 1993, tailings reservoir of mass landslide occurred within, causing landslides, four people killed 14 people seriously, hubei daye non-ferrous metals company dragon horn mountain copper July 16, 1994, tailings dam due to heavy rains caused by impact, 28 people died, 3 missing. On October 28, 2000, nandan county in guangxi giant town acid water bay dam collapse target.we concentrator, causing the sudden 28 deaths, 百万座 homes were destroyed, every time tailings DAMS accident not only causing casualties, and financially disastrous [1]. Therefore, tailings dam safety monitoring more and more attention by people, with the rapid development of computer technology, produced automatic monitoring method, namely through the automated monitoring instrument, the observations of observation data collection to data acquisition instrument, and through the automatic monitoring software for data analysis and processing, achieve real-time monitoring purposes. Tailings dam automatic monitoring and security warning is the need of modern management, and establish advanced computer monitoring system is also and contemporary hi-tech development adaptation.
2 influence of tailings dam safety index and its realization
Influence of tailings dam safety index basically has: the tailing dam, internal displacement monitoring (surface), tailings DAMS saturation line, water and dry beach length Chambers, the realization of monitoring index as follows [3] :
(1) dam saturation line monitoring:
Embedded within the dam PVC pipe, tube drilling project can be put infiltration pressure, the water level of the real-time data acquisition tube, the system software data automatically draw the dam the distribution of saturation line. Managers can real time control of the actual circumstances of the dam saturation line, overcome such harsh conditions in flood season, artificially cannot measure or measuring prohibit of drawbacks. Beside the point in reserve artificially hole, the accuracy of calibration sensor.
(2) library water-level monitoring:
Adopt water meter reservoir water level, in monitoring embedded water crisis, Chambers by polyurethane cables and MCU data acquisition instrument is linked together, can monitor the water [4].
