In 2022, the outbreak of the Russia-Ukraine conflict has dramatically changed global coal trade, price levels, and supply and demand patterns. The surge in natural gas prices has triggered many consumers to switch from natural gas to other energy sources, driving up demand for more price-competitive sources of energy, including coal. According to the annual coal market report “Coal 2022” (Coal 2022) released by the International Energy Agency (IEA), in 2022, global coal demand will increase by 1.2% year-on-year, reaching a record high, exceeding 8 billion tons for the first time, surpassing the record in 2013. historical record. The report also predicts that in 2022, global coal production will increase to 8.318 billion tons, an increase of 5.4% from 7.888 billion tons in the previous year, also hitting a record high. The world’s three major coal producers, China, India and Indonesia, are all expected to hit record highs in coal production in 2022.
China’s raw coal production reached a new high and maintained steady and rapid growth in the first quarter
According to the National Bureau of Statistics, in 2022, China’s raw coal output will be 4.5 billion tons, a year-on-year increase of 9.0%, and the output will hit a record high again, with an accelerated year-on-year growth rate. In the first quarter of 2023, China’s raw coal output will be 1.15 billion tons, a year-on-year increase of 5.5%, and continue to maintain a steady and rapid growth.
Accelerating the construction of a modern coal industry system, reducing the total number of coal mines, and increasing the intensity of safe and efficient coal mines
In December 2016, the National Development and Reform Commission issued the “Opinions on Accelerating the Development of Iron and Steel Capacity Reduction and Coal Reduction”. The “Opinions” mentioned that by 2020, coal production capacity will be reduced to less than 550 million tons. Under this double reduction policy, the number of coal mines in my country has been significantly reduced. In the past ten years, the number of coal mines in the country has decreased from 13,000 to less than 4,400; at the same time, the number of safe and efficient coal mines has increased from 406 to 1,146, and the proportion of output in the country has increased from about 30% to more than 70%.
Coal mine accidents are decreasing year by year, coal mine strengthening agent helps coal mine safety production
In recent years, with the intensive development of coal mines in my country, the total number of coal mine accidents has decreased year by year, and the rate of decline has slowed down. As can be seen from the figure below, from 2008 to 2021, the number of coal mine deaths in my country and the death rate per million have declined. The death rate per million has dropped significantly from 1.182 people/MT in 2008 to 0.044 people/MT in 2021.
The actual demand for coal mine safety production has brought a broad market space for mine safety materials
The main purpose of mining safety materials is to control underground disasters and assist mining. Its purpose is to use the inherent physical and chemical properties of materials to reinforce and fill the interior of mines, waterproof and prevent fires, and prevent and control mining environments with potential disasters in advance. Effectively manage the site to avoid the expansion of disasters. Safe production is the focus of my country’s coal mining activities. The introduction of a series of measures around coal safety production is the cornerstone of stabilizing coal supply, improving mining efficiency, and ensuring the personal and property safety of coal workers. The mandatory requirements for safe production in the coal industry have driven the market demand for mining safety materials. The extensive use of mining safety materials has effectively reduced the death rate in coal mining activities and escorted the safe production of coal mines in my country.
Classification of mine safety materials
At present, the commonly used polymer mining safety materials mainly include the following categories: acrylamide, epoxy resin, urea-formaldehyde resin, phenolic resin and polyurethane. Among them, the polyurethane mining safety material (polyurethane coal mine reinforcement) is obtained by mixing isocyanate (polymeric MDI), polyether polyol and various additives, and has strong constructability, strong customizability, high density, and mechanical properties. Strong, high stability, easy storage and other advantages.
During the use of coal reinforcement technology, polyurethane hard foam black and white materials (A material, B material) are mixed by a pneumatic grouting pump and then injected into the coal seam, contacting the coal rock mass and flowing into the coal seam, and the mixed material is in about 3 minutes. Under the action of the catalyst, the foaming reaction begins in the voids of the coal body, the volume expands and some heat is released, and complete solidification can be achieved after 2 hours.
In addition to mining, this kind of material can also expand the applicationUsed in heavy-duty trains and railway tunnels and other fields. Related domestic manufacturers include BASF Haoke Mining, Qingdao Xinyutian, Coagulation Force and Shandong Duowei.
In recent years, with the development of domestic consumption of polyurethane coal mine reinforcement products, it also promotes the demand for polymeric MDI and polyether polyols growth in demand.
