It is said that Europe is currently experiencing an energy crisis, and some time ago there was also news that China's "warm three-piece" is very sought-after in Europe, which is also inseparable from this
.
For environmentalists, this is not good news, because some experts predict that global coal demand may reach another peak after a sustained slump, especially as the heating season has arrived, and priority supply will become a more critical demand
.

However, the coal market pattern is different from 10 years ago, because clean coal and clean coal production sing the main theme, typical is our China
.

Those who follow the 20th National Congress should know that on the afternoon of October 18, the spokespersons of delegations from seven provinces, autonomous regions and municipalities, including Beijing, Tianjin and Hebei, received the first collective interview
.
Among them, a relevant spokesman in Shanxi said that as a major coal province, it must "resolutely shoulder the major political responsibility of ensuring national energy security, and must not let the country worry about coal"
.
To this end, Shanxi has specially put forward the requirement
of "three stability and three prohibitions.
"

"We have the confidence, ability and determination to do a good job in increasing energy production and ensuring supply", and under such voices, Shanxi also said that it will promote the "five integrations" in the energy field - the integrated development of coal and coal power, the integrated development of coal power and new energy, the integrated development of coal and coal chemical industry, the integrated development of coal industry and digital technology, and the integrated promotion
of coal industry and carbon reduction technology.
It is impossible to follow the old road, this is the principle of the development of
the coal industry in the new era.

In addition to ensuring supply, Shanxi is also constantly promoting digital reform and low-carbon upgrading
.
Not long ago, Shanxi has just formulated the first provincial local regulation specifically for the promotion of clean and efficient utilization of coal - "Shanxi Province Clean and Efficient Coal Utilization Promotion Regulations (Draft)", which has been publicly solicited for comments, and Shanxi's "Implementation Opinions on Improving the Institutional Mechanism and Policy Measures for the Green and Low-carbon Transformation of Energy" also clearly mentioned that vigorously promote the clean and efficient use of coal, formulate a high-quality development promotion mechanism for the coal industry, and establish a long-term mechanism for the green development of
coal mines.

The clean and efficient utilization of coal and the green development of coal mines are both worthy of focus
.

Clean and efficient use of coal, not burned, nor simply used as fuel, for example, coal liquefaction, coal indirect liquefaction, and coal to hydrocarbons these three process routes are currently more commonly used
.
In essence, it is the change of coal from fuel to raw materials to reduce carbon emissions
from coal utilization.

Not long ago, the world's largest coal-to-hydrogen pressure swing adsorption device project was put into operation in Yulin, Shaanxi Province, which is a typical case
of coal "from fuel to raw material".
It is reported that the coal hydrogen production project uses coal as raw material, with a total annual hydrogen production capacity of 350,000 tons, high carbon conversion rate, high heat utilization efficiency, low oxygen consumption, compared with natural gas hydrogen production, the cost can be reduced by 20% to 25%, and can carry out resource recovery and carbon emission reduction, helping coal to achieve clean and efficient utilization
.

At the same time, industry insiders also pointed out in the study that coal-fired power generation technology, integrated coal gasification combined cycle (IGCC) power generation technology and coal gasification fuel cell combined cycle (IGFC) technology can all be the focus of
clean and efficient utilization of coal.
Let the energy value of coal is no longer limited to "burning", but to use, synchronously, and the mining of coal mining areas can not be delayed
.

Towards the dual carbon goal, China's coal industry is also continuing to promote the construction of
green mining areas.
In 2019 and 2020, a total of 1,254 companies were selected, including Majialiang Coal Mine, Shaqu No.
1 and No.
2 Coal Mine, Houcun Coal Mine, Hexi Coal Mine, Dongqu Coal Mine, Trabra Coal Mine, Yuanbaoshan Open-pit Coal Mine, Yixin Coal Mine, Tashan Coal Mine, Yushujing Coal Mine, Daxing Coal Mine, Kongzhuang Coal Mine, Yangliu Coal Mine and so on
.

How to build a green mine? Taking Daliuta Coal Mine as an example, (1) intelligence - improve production efficiency, achieve precise exploration, safe and efficient development, energy efficiency improvement, carbon emission control, Daliuta uses a variety of "black technology" products
including data monitoring, remote control, intelligent analysis and alarm, intelligent speed regulation of the main transportation system, tape machine inspection robot, PLC control box, coal machine information perception and so on.

(2) Dry pressing type - using the remining process along the empty alley, the layered mining of extra thick coal seam is carried out, and a new process of advanced boring of windlass and lagging expansion of continuous mining machine is proposed, which can recover 12.
1 million tons of coal resources and create a profit of 3.
6 billion +
.
In addition, the disposal rate of gangue reached 100%, the annual utilization scale exceeded 250,000 tons, and the mine water was "tertiary treatment, three types of recycling, and three utilization", and the scale of reused water in 2020 exceeded 11 million tons, with a utilization rate of 75.
8%.

(3) Energy conservation and emission reduction formula - introduce energy conservation and emission reduction technology and equipment, and implement clean energy transformation projects
.

It has to be said that there are many articles that can be written in the construction of green mining areas, and visible results
have been achieved.
Public data show that in the 10 years from 2010 to 2020, China's average greenhouse gas emissions from the production of 1 ton of coal fell from 226.
7 kg to 151.
1 kg, that is, almost one-third, which is very impressive
.

The guarantee of supply can not be less, and the clean utilization does not conflict
.
Under the dual carbon goals, the pace of energy supply-side reform will not stop, and the clean utilization of coal and the low-carbon development of the coal industry are also important links
.
