【Chemical Machinery and Equipment Network Policies and Regulations】Green coal mining refers to making the disturbance of coal mining to the mining area environment less than the regional environmental capacity from the source, optimizing the development and utilization of resources and minimizing the ecological environmental impact, and forming a mining mode
of "high utilization, low emission, and near-zero damage" that is in harmony with the environment.
Green coal mining technology is a key and supportive mining process or method
adopted in the process of realizing green coal mining.
of "high utilization, low emission, and near-zero damage" that is in harmony with the environment.
Green coal mining technology is a key and supportive mining process or method
adopted in the process of realizing green coal mining.
Recently, the Shanxi Provincial Administration for Market Regulation released the standard document "DB 14/T 2535-2022 Technical Guide for Green Coal Mining", which is scheduled to be implemented
from December 1, 2022.
The document gives the general principles and technical route guidance for green coal mining, which is applicable to the technical selection
of green mining in underground coal mines in the province.
from December 1, 2022.
The document gives the general principles and technical route guidance for green coal mining, which is applicable to the technical selection
of green mining in underground coal mines in the province.
The document requires adherence to three general principles: First, adhere to the combination of ecological priority and benefit priority, and improve the ability of water resources protection, strengthen the comprehensive utilization of gas, increase the comprehensive utilization of solid waste and ecological restoration throughout the whole process
of coal development.
The second is to adhere to the combination of regional layout and local conditions, adhere to the red line thinking of safe production and ecological protection, uphold the principles of technical feasibility and economic rationality, and coordinate the promotion of green mining
according to mine policies.
The third is to adhere to the combination of first implementation and gradual promotion, according to the actual situation of coal mines, reasonably determine the green mining test area and technical route for testing and demonstration, and gradually promote
it after success.
of coal development.

The third is to adhere to the combination of first implementation and gradual promotion, according to the actual situation of coal mines, reasonably determine the green mining test area and technical route for testing and demonstration, and gradually promote
it after success.
In terms of green coal mining, the document elaborates
on coal gangue return to wells, solid filling mining, paste, high water and ultra-high water filling mining, water retention mining, surface coalbed methane extraction, coal mine underground gas extraction, coalbed methane (gas) utilization, other processes and methods.
on coal gangue return to wells, solid filling mining, paste, high water and ultra-high water filling mining, water retention mining, surface coalbed methane extraction, coal mine underground gas extraction, coalbed methane (gas) utilization, other processes and methods.
The document also points out that technology needs continuous improvement, and it is advisable to include green mining technologies that are not recorded in this document but use new concepts and new paths that also save coal resources, improve efficiency or protect the environment according to the continuous innovation and development of technology, and after comprehensive assessment, they should be included in the document in a timely manner
