a new form of rogue software CTB locker uses despicable means to send infected e-mail to the victim. Only when the victim opens it, the ward will invade the victim's personal computer and encrypt the victim's specific files (JPEG image is a popular target). If the victim wants to retrieve the files, he must pay a ransom in bitcoin. A user paid a ransom of three bitcoins in four days, about $700 (market value on Friday)
the email messages they send are usually hot topics, such as: what is bitcoin? Some of the victims were cheated by curiosity. At present, some users have been affected. This is part of the content intercepted on bitcoin home.
1、 Open pit mining: in general, diamond mines are mined around kimberlite pipes. The middle of the pipes is the place where high-quality diamonds are most concentrated, which is usually characterized by huge holes. When the Kimberley rock pipeline was found, miners g out vertically from the ground surface
Second, underground mining: this mining method is safer and more efficient, especially with the deepening of the mining process, it is difficult to judge whether to continue mining to expand the mine. Underground mining only needs to open a tunnel to extract diamonds under the surface, which is more reasonable and less dangerous. Sometimes a combination of underground and open-pit mining is used to make a tunnel from the pit into the surrounding rock Extraction of kimberlite from the mine: kimberlite can be released from the earth's crust by artificial explosion, and a large number of rocks can be destroyed by explosion, but it can not be detected on site. It is wrapped with diamonds and must be transferred to another place for processing and diamond extraction by large trucks and steam shovels, Generally speaking, there are 0.5 carats of diamonds in one ton of mud (4) percussive Mining: rivers and streams will bring kimberlite to the river bed, shore, or even coastal zone to form percussive sand deposits. Percussive mining is also known as artificial mining, because the miner has to go to the percussive sand deposit to search for diamonds artificially. The farther away from the kimberlite pipeline, the lower the output of diamonds and the more sparse the distribution density of diamonds. Therefore, percussive mining is not suitable for instrial diamond mining
extended data
1. The Kimberley diamond deposit was discovered by the Burnett brothers in 1870. It is this discovery that makes people know which kind of rock may contain diamond. It's a volcanic rock formed after the magma of ancient times cooled. In places where garnet and olivine are proced, the possibility of finding diamond is relatively high. Therefore, garnet and olivine become the "indicator minerals" for diamond
From 1866 to 1914, 50000 miners used shovels and other tools to excavate, and a total of 2722 kg of diamonds were excavated. The South African government is trying to apply for the Kimberley pit as a world heritage site Third, open-pit mining is a process of removing the covering from the ore body to obtain the required minerals and extracting useful minerals from the open surface stope. Open pit mining operation mainly includes perforation, blasting, mining and loading, transportation and mping. Compared with underground mining, open pit mining has the advantages of full utilization of resources, low dilution rate, suitable for large-scale mechanical construction, fast mine construction, large output, high labor proctivity, low cost, good working conditions and safe proctiontry Tencent computer housekeeper, which adopts the latest Trojan cloud killing technology and establishes a powerful popular Trojan horse analysis and processing system in the background. As long as a user submits a suspicious file, it can extract dangerous samples such as Trojan virus in the first time, which will help all computer housekeeper users to kill the latest popular Trojan horse
