The significance of filling tailings paste in mines

Add Time：2025-04-02

The significance of tailings paste filling in mines lies in the development requirements of green mining in coal mines and the urgency of coal mining in villages. The technology of using paste filling without relocating villages for coal mining has been proposed. By developing specialized sound body filling and bonding materials and selecting inexpensive filling materials, the cost of body filling has been significantly reduced, and the reasonable ratio of head body materials suitable for coal mining has been improved. A suitable method for grinding forest filling for coal standing has been proposed, and the application of green body filling in coal and practice has been systematically introduced. China University of Mining and Technology recently proposed coal and green mining technology, and backfill mining technology is an important and integral part of green mining technology, which is an ideal way to solve the environmental problems of coal mining. At present, there is a large amount of manual coal mining in buildings such as Yanbaojie Village, and the realization of non village coal mining should be given more attention. China's village jade mining has the characteristics of large quantity and wide coverage. There are 094 jade fruits from Renhuaji in the south, Guo'er, Shandong, Nvhui, and Gongyang, and the number of active or civilian classes in households is M55 or more. The coal mining volume in each village reaches 5.5 billion, and the annual material ear mining needs in the mountains, as well as in various aspects such as mountainous areas, environmental protection, and industrial relationships. Jia, the amount of coal mined by Murakami Tian is still based on the fact that after the village of Zhijiang was established, the Buyi Prefecture asked Wu and Shi Nandi to compensate him with a generous sum of 200000 yuan per household, and the mountainous area caused a loss of territory
