Zhu Deren, vice president of the China Coal Industry Association, said that coal bed gas is also called gas, which is mainly unconventional natural gas generated during the coal formation process and mainly used as a coal bed, also known as coal bed methane. It can burn, generate electricity, can be widely used in automotive fuels and chemical raw materials, but it is also the main reason leading to the "greenhouse effect." It is also the number one killer of coal mine safety production. In recent years, most of the coal mine safety accidents in China have been caused by gas explosions.
It is understood that China’s CBM resources of 2,000 meters below the surface range from 30 trillion to 35 trillion tons, ranking third in the world, and is equivalent to conventional natural gas reserves. At present, the world's major coal-producing countries have attached great importance to the development of CBM resources, not only making it a new energy source, but also reducing CO2 emissions from coal combustion. According to the "Kyoto Protocol," the World Bank Carbon Fund purchased a 4.5-million-ton carbon dioxide gas emission reduction target for 10 years from China's Shanxi Coal Group at the end of last year, bringing the price to 19 million US dollars. China, as the world’s largest producer of coal, has long been lagging behind in the development and utilization of coalbed methane resources, and its threat to production safety has become increasingly severe.
In recent years, with the improvement of energy status, China has begun to attach importance to the industrialization of coalbed methane. On May 29th, 2000, China's first coalbed methane external cooperation project, Huaibei coalfield in Anhui Province, was successfully developed. The total investment of the cooperation project is 500 million U.S. dollars, and it is estimated that 500 million cubic meters of coalbed methane will be produced annually. Recently, the relevant state departments formally approved the Shanxi coalbed methane development and utilization project with a total investment of more than 2 billion yuan. The “Methane Commitment to Market Strategic Partnership Program†developed in the United States in November last year has officially started, and China has also become one of the 13 member states. These all indicate that during the “Eleventh Five-Year Plan†period, the industrialization of CBM in China will accelerate development.
According to Vice President Zhu Deren, however, there are many bottlenecks in China's CBM industry, such as low level of development technology, insufficient exploration and development, and high risk investment.
Conveyor Components are essential spare parts of conveyor system. There are many types of conveyors are available, such as screw, chain and pneumatic. The most commonly used is the belt conveyor. Belt conveyors are the backbone of bulk material handling systems in many different processing plants. These systems use carts or trains to carry heavy materials like rocks or metal. Such as bulk material handling conveyor or bulk conveyor. The main function of a bulk conveyor system is to continuously transport and supply bulk materials to units in processing plants. Secondary functions include storage and blending.
Please see the structure of typical bulk conveyor below:
The structure of a roller conveyor consists of a series of tubes mounted at set intervals. Designed for continuous operation, a belt conveyor can be used in a wide range of capacities and distances, and its length can be a few meters or tens of kilometers.
Raw materials (such as bulk solids and powders) are received from trucks, ships or trains. Then they are unloaded to a yard or storage facility, often using a conveyor system. At either end of the conveyor, the belt wraps around a pulley. To maintain reliability, the principal Belt Conveyor Components – such as idlers, rollers, pulleys, bearings, shafts and belts – must operate under dynamic loads and harsh conditions.
