Onda graphics mining

1. mining must first consider a card, and then consider cheap n card before 799 Onda. It's really not good. It's a high-end n card. The computing power of 1066 is about 21. I'm afraid something's wrong with you

3. The data cable of the monitor should be connected to the single display interface. Press the F2 or del key to enter the BIOS when starting up.

4. 1050 or notebook want to mine? Prepare to dig out half a bitcoin in 20 years

5. The motherboard has six pcies × 1 graphics card slot, which can be used to install PCI graphics cards including rtx2060s, and can insert up to six graphics cards of the same model for mining.

6. Because of the brand's three line positioning, it can't raise the price too high. In addition, the design is a public version design, with 2 + 1 power supply and very cold mixing. In terms of heat dissipation, it uses a single fan and an ordinary aluminum radiator, which is very cheap as a whole. So you can go to 849
in terms of disadvantages, the public version design saves materials, so the frequency preset is very low, the overclocking potential is poor (some people still pull 100 cores directly in use), and the heat dissipation is not so good, but it can still be used normally.

Baimaoling fluorite mine is located in Sanbao village, Huagu Township, 15km north of Guangde County, southeast corner of Anhui Province. It is composed of two ore blocks of huangniushan (also known as sanjuan) and Baiyunshan. It starts from Baiyunshan in the north and ends at the foot of huangniushan in the south. It is about 500 meters wide from north to South and 800 meters long from east to west, covering an area of about 0.4 square kilometers

the mining area is 1.5km away from Langguang highway in the north and 10km away from national highway 318 and Xuanhang railway in the south

the Baimaoling fluorite deposit is located in the NNE trending uplift fault fracture zone at the contact part of xuanlang depression and Guangde depression, which is a large vein fluorite deposit filled with medium low temperature hydrothermal solution controlled by the fault fracture zone. There are 23 veins in total. The shape of the veins is regular, and most of them are plate-like bodies, dipping to the South with an angle of 40 °— fifty ° And 70 °— eighty °， The maximum extension is 330m and the maximum depth is 300m. The ore is quartz fluorite type, the mineral composition is mainly fluorite and quartz, followed by calcite and barite, a small amount of pyrite, sphalerite, galena, etc. the ore is mainly lean ore, and the average calcium fluoride content of the ore section is 51% - 70%

The wall rock of the ore body is silicified clastic rock and siliceous rock, and their boundaries are clear; Silicification is the most common wall rock alteration, followed by KAOLINIZATION and pyrophyllization

The genesis of the deposit is related to the late Yanshanian Yaocun granite and its derived granodiorite porphyry

Before the founding of the people's Republic of China, no geological survey was done here, only two ancient excavation traces were found about 100 meters in front of yun'an gate on the top of Baiyun Mountain, which indicates that fluorite may have been discovered by predecessors, but the details cannot be verified

After the founding of the people's Republic of China, with the development of iron and steel instry by the whole people in 1958, the demand for mineral raw materials related to the development of iron and steel instry has become increasingly tense. Under this situation, the rise of prospecting, mining and geology by the whole people has been promoted. In September 1958, fluorite was discovered in Baiyunshan by Shanghai Baimaoling farm, and then surface mining was carried out. In the second half of the same year, Li Huairong, the third geological team of Wuhu geological branch of the Provincial Geological Bureau, came here to investigate the iron ore and found fluorite, but no work was carried out. In October 1959, the geological team of Guangde County sent personnel here to conct fluorite survey. Fluorite fragments and mineralization were found on the surface of huangniushan mountain. Then, the exploration trench was used to expose the fluorite veins. The existence of the deposit was preliminarily determined and the ore quantity was estimated. The work summary of the geological team of Guangde County in 1960 and the general survey and evaluation report of Baimaoling fluorite mine and Sanyuan fluorite mine were compiled. In May 1960, the third unit of 322 team of the Provincial Geological Bureau sent personnel here to carry out fluorite survey. In January 1961, Wang Wenxin compiled the evaluation report and survey and exploration design book of Baimaoling fluorite mine in Guangde County, but the survey and exploration design was not put into practice. In June 1972, the first unit of 322 team carried out geological exploration in huangniushan ore block, started a drilling rig, and by the end of exploration in August 1974, the drilling footage was 3400 meters, including 26 boreholes. The proved reserves of fluorite ore were 883400 tons. In December 1977, the geological exploration report of huangniushan ore block of Baimaoling fluorite deposit in Guangde County was submitted. On January 26, 1979, it was examined and approved by the provincial mineral reserves Committee. The geological exploration cost is about 170000 yuan, and the average exploration cost per ton of ore is about 0.20 yuan

after the exploration of huangniushan ore block was completed, the general survey of Baiyunshan ore block was carried out in September of that year. The first stage of work came to an end in July 1976. In August of the same year, the drilling rig was dispatched to Ma'anshan to participate in the iron ore exploration battle; At the end of 1979, the drilling rig was moved back to Baiyunshan ore section for construction. Later, e to the complex stratum, fragile ore, backward drilling technology and other factors, the quality of drilling engineering was very low, and it was difficult to meet the geological requirements, so the drilling construction was stopped, and the total drilling workload was 14000 meters. In August 1980, the general survey and evaluation report of Baiyunshan ore block of Baimaoling fluorite deposit in Anhui Province was submitted, and the fluorite ore reserve was 1046700 tons

In September 1958, Baimaoling fluorite mine was first mined by Shanghai Baimaoling farm. The next year, Chengguan town of Guangde County also organized mining, and took over the mining site of Baimaoling farm in 1960. Mining was stopped in 1961 and resumed in 1965 until 1972 when the fluorite mine in Guangde County, a local state-owned mine, took over the mining. Before 1987, it was small-scale open pit mining, and then fluorite mine designed and constructed its own wells for underground mining; There is a middle mining section with a height of 40 meters. At present, there are 167 employees, 205 in peak period, with an annual output of 13000-14000 tons of ore. The ore can be sold after manual separation, so its economic benefit is good

since the reform and opening up, with the graal implementation of the policy of enriching the people, around 1986, fluorite mine in the county gave back the mining site of Baiyunshan mine section to the villages of which the mine belongs, thus setting up a number of small rural mines. At this point, the mining pits in the mining area are all over the mountains, the sound of mining guns is continuous, and the transport trucks shuttle back and forth, showing a busy scene of mining, which adds vitality to the development of local and township economy
