Substantiation of technologies and technical means for disposal of mining and metallurgical waste in mines

The object of research is environmental and resource-saving technologies in underground mining of mineral deposits with the laying of the developed space. One of the most problematic places is the delivery of hardening filling mixtures to the place of their installation and the lack of components fo...
