Forecasting resources for coal prospecting prospects
This time, China's coal resources are 18440.48 x 108t in the shallow depth of 1000m, and 27080.56 x 108t in the vertical depth of 1000 ~ 2000m, totaling 45521.04 x 108t, indicating that coal has not been found in China.
Great potential for charcoal resources. Under the current technical and economic conditions in China, shallow prediction resources with a depth of 1000m are likely to be the target of coal census, while the depth of the depth of 1000m is the predicted resource, except for a few cases, there is basically no realistic meaning of coal. Therefore, the prospect of studying the coal census is mainly for the forecasting resources of this part with a depth of 1000m.
According to the prediction results, the shallow depth of 1000m can be divided into four cases:
(1) There are five provinces (districts) including Shanxi, Inner Mongolia, Guizhou, Shaanxi, and Xinjiang. The predicted resources are 16625.34 x 108t.
(2) The conditions are generally ten provinces (autonomous regions and municipalities) such as Henan, Shandong, Anhui, Heilongjiang, Sichuan, Ningxia, Gansu, Yunnan, Hebei, and Beijing. The predicted resources are 1435.30x 108t.
(3) The provinces (districts) with poor conditions are Jilin, Liaoning, Fujian, Jiangxi, Hunan, Guangxi, etc. The predicted resources are 145.10 x 108t. These provinces (regions) are mostly resource-poor areas, so although the scale of resources is predicted to be small, there is still a certain value of coal census. In addition, Qinghai's predicted resources of 208.41 x 108t are mostly in the alpine zone, with poor climatic conditions, difficult transportation and extremely poor conditions.
(4) The provinces (districts) with small scale and complicated geological conditions are Jiangsu, Guangdong, Hainan, Tibet, Hubei, etc. The predicted resources are only 26.33 x 108t. There is basically no prospect of looking for coal. Zhejiang and Tianjin have no resources buried deeper than 1000m.
According to the feasibility classification of coal census, the predicted depth of the shallow depth of 1000m in the Class I prediction area is 3592.76 x 108t, of which 218 prediction areas may be used as the “target area†for the recent coal census. The total amount is 2862.45 x 108t. This part of the forecasted resources is classified according to coal type, lignite 356.91 x 108t, accounting for 12.50; low metamorphic bituminous coal 1204.15 x 108t, accounting for 42.10; medium metamorphic bituminous coal 597.88 x 108t, accounting for 20.90; lean coal, anthracite coal 703.51 x 108t, accounting for 24.50.
Among the provinces (cities) in the eastern part of China, Jiangsu, Zhejiang, Hubei, Hainan and other provinces have no “target area†for the recent coal census. Liaoning, Jilin, Guangdong and other provinces have a total of 9 “target areas†with a predicted resource of only 2.48. x 108t. In Beijing, Hebei, Shandong, Henan, Anhui and other provinces (cities), there are 23 “target areas†with a predicted resource of 61.74×108t, some of which are relatively large-scale and well-conditioned coal prospecting targets in the eastern belt. In the provinces of Fujian, Jiangxi, Hunan, Guangxi and other provinces (regions), there are 60 “target areas†with a predicted resource of 26.03 x 108t. Some of the coal producing areas in Hunan Province have relatively good resource prospects and prospects for coal prospecting. Other provinces (districts) Although there are some prediction areas that can be used as "target areas", the resources are very small, the distribution is sporadic, and the conditions are also poor. In addition, the predicted resources of 17 “target areas†in Heilongjiang are 25.20 x 108t, of which lignite accounts for more than half, and the Sanjiang-Muling coal-bearing area has certain gas and coal resources. In general, the main target areas for coal search in the eastern zone are located in the periphery and deep of the old mining area.
Johnson Screen Sieve Plate is a stainless steel Filter Element and is used for screening and filtering. Johnson screen sieve plate is made of v-type wire and support rods rolling welded on the special welding machine. The filtration mode can be divided into two types: from the outside to the inside or from the inside to the outside.
To suit the need of customers, we can use many kind of metal material such as: 304, 321, 316 L, 904 L, duplex steel 2205, duplex steel 2207, Monel, and Hastelloy.etc.
Johnson screen sieve plate is widely used in many industries, such as screening, filtration, dehydration, desliming and other operations.
