Abstract: While China is vigorously developing its social economy, it has also caused certain pollution and damage to the environment. In the production and operation process of the coal industry, in order to better meet the massive demand for coal resources in the production and life of modern society, various coal mining engineering activities have been carried out continuously, causing a series of environmental and ecological problems, which to a large extent restricts the upgrading and development of the industrial structure. In this regard, we should promote the greening of coal mining machinery, gradually improve manufacturing technology, so that coal mining machinery can operate efficiently in various environments, and minimize environmental pollution and energy consumption caused by machinery operation. In view of this, based on clarifying the connotation of green design and manufacturing technology for coal mining machinery, this article analyzes the green design of coal mining machinery and the manufacturing technology of coal mining machinery products, and discusses them with specific cases.
