The price of the market is not spectrumd. Sometimes there is no relocation but the township builds its own coal mine.
According to the person in charge of the company, they are forced to do so. The production of all the products of Qianhua Chemicals depends on coal for its raw materials. In recent years, domestic coal supply has been tense, prices have been rising, and coal prices have sometimes been as high as more than 700 yuan per ton at the time of factory relocation, and this has caused delays. This has made passive production very passive. Faced with this situation, either completely change the current production process, or find ways to solve the raw materials themselves. After repeated weighing, migration finally chose the second way.
Fortunately, since the beginning of last year, the reform of the business circulation of coal mining rights has started. The fertilizer companies have the possibility of obtaining coal mining rights. After some arduous efforts, Qianhua finally obtained the mining rights of the West District coal mine in Chifeng City, Inner Mongolia. The mine has a coal resource reserve of 1,925.8 million tons and an annual production capacity of 1.8 million tons. It can supply raw coal for supply for a period of 32 years, and the mine has officially started construction last month. For double insurance, Qianhua talked about the exploitation of an open-pit coal mine with an annual output of 10 million tons.
With the protection of raw materials, we must dare to think about the future development. It is understood that Qianhua currently builds mines on one side and begins the construction of a total scale 600,000 tons of coal-made methanol project. The project adopts CSP dry pulverized coal pressurized gasification equipment and chilling process pressure gasification technology from Germany Future Energy Company, and is located near the coal mine nearby. The first phase of the project produces 200,000 tons of methanol annually and 1,300 tons of sulfur, with an estimated investment of over 800 million yuan. Yuan, duration 36 months. After the completion of the project, annual sales income of 1 billion yuan and profits and taxes of 300 million yuan can be realized. With coal, Qianhua also plans to invest RMB 9 billion to build an annual output of 600,000 tons of synthetic ammonia, 1.04 million tons of urea and 1.2 million tons of methanol.
It is understood that at present, many chemical companies have to adopt various “self-prepared†methods to solve the situation where the required conditions cannot be guaranteed. As a result, self-provided railways, self-owned mines, self-provided salt mines, and self-provided power plants emerged... This aspect has strengthened the company’s ability to cope with various market difficulties, to some extent eased the pressure on production, but on the other hand, Reduced the level of enterprise specialization and production efficiency.
Editor's note: To tell the truth, when compiling this news, the editor's mood was a bit complicated and he couldn't say whether this should be a good news or a bad news. From the standpoint of relocating an enterprise, of course, it should be considered good news. The so-called everything is not asking for help. The more self-owned facilities, the less worries the company has. At the very least, there will be no worry about raw materials in the coming period of time. However, from the perspective of the modern economy, this news is hard to make people feel relieved. Just think, if large and small enterprises have to build their own facilities, aren't we going to reverse the socialization and production that are more and more professional? If this is really the case, and what kind of market economy is still in place, everyone will become a self-sufficient native landowner. Besides, how can non-professional self-provided facilities of enterprises be managed as professionally as possible, or how many kinds of talents will enterprises have to deploy? Then, how can guarantees such as the rational use of resources, environmental protection, and safety be guaranteed?
The increase in the number of company-owned facilities shows that the current contractual relationship has failed. This does not bode well for establishing a market economy.
Dredging is an excavation activity usually carried out underwater, in shallow seas or freshwater areas with the purpose of gathering up bottom sediments and disposing of them at a different location. This technique is often used to keep waterways navigable. It is also used as a way to replenish sand on some public beaches, where sand has been lost because of coastal erosion. Dredging is also used as a technique for fishing for certain species of edible clams and crabs (see fishing dredge).

Types of dredging vessels
Suction

For suction-type excavation out of water, see Suction excavator.
These operate by sucking through a long tube, like some vacuum cleaners but on a larger scale.
A Plain Suction Dredger has no tool at the end of the Suction Pipe to disturb the material. This is often the most commonly used form of dredging.[citation needed]
Trailing suction
A trailing Suction Hopper Dredger (TSHD) trails its suction pipe when working. The pipe, which is fitted with a dredge drag head, loads the dredge spoil into one or more hoppers in the vessel. When the hoppers are full, the TSHD sails to a disposal area and either dumps the material through doors in the hull or pumps the material out of the hoppers. Some dredges also self-offload using drag buckets and conveyors.
The largest trailing suction hopper dredgers in the world are currently Jan De Nul's Cristobal Colon (launched 4 July 2008) and its sister ship Leiv Eriksson (launched 4 September 2009. Main design specs for the Cristobal Colon and the Leiv Eriksson are: 46,000 cubic metre hopper and a design dredging depth of 155 m.[3] Next largest is HAM 318 (Van Oord) with its 37,293 cubic metre hopper and a maximum dredging depth of 101 m.
Cutter-suction
A cutter-suction dredger's (CSD) Suction Tube has a cutting mechanism at the suction inlet. The cutting mechanism loosens the bed material and transports it to the Suction Mouth. The dredged material is usually sucked up by a wear-resistant centrifugal pump and discharged either through a pipe line or to a barge. Cutter-suction dredgers are most often used in geological areas consisting of hard surface materials (for example gravel deposits or surface bedrock) where a standard suction dredger would be ineffective. In recent years, dredgers with more powerful cutters have been built in order to excavate harder rock without the need for blasting.
The two largest cutter suction dredgers in the world are currently (as at August 2009) DEME's D'Artagnan (28,200 kW total installed power)and Jan De Nul's J.F.J. DeNul (27,240 kW).both built by IHC Merwede.
Auger suction
This process functions like a Cutter Suction Dredger, but the cutting tool is a rotating Archimedean screw set at right angles to the suction pipe. The first widely used auger dredges were designed in the 1980s by Mud Cat Dredges, which was run by National Car Rental, but is now a Division of Ellicott Dredges. In 1996, IMS Dredges introduced a self-propelled version of the auger dredge that allows the system to propel itself without the use of anchors or cables. During the 1980s and 1990s auger dredges were primarily used for sludge removal applications from waste water treatment plants. Today, auger dredges are used for a wider variety of applications including river maintenance and sand mining.
The most common auger dredge on the global market today is the Versi-Dredge. The turbidity shroud on auger dredge systems creates a strong suction vacuum, causing much less turbidity than conical (basket) type cutterheads and so they are preferred for environmental applications. The vacuum created by the shroud and the ability to convey material to the pump faster makes auger dredge systems more productive than similar sized conical (basket) type cutterhead dredges.
