Article discusses preliminary work results carried out by the Kazakh National Research Technical University (KazNIRU) named after K.I. Satpayev together with the Central Laboratory for Certification of Building Materials (CLCBM) on resource saving and recycling of industrial waste to obtain demanded building materials. Processing of industrial wastes (wastes of enrichment and processing, overburden and enclosing rocks), close in composition to natural and used in traditional areas, practically does not differ from the industrial processing of natural mineral raw materials. Creation of efficient technologies for processing of technogenic raw materials is urgent task, which make it possible to obtain competitive products from it for various industries. Utilization of waste from mining and metallurgical complexes makes it possible to reduce technogenic load on the environment and ensure rational use of secondary raw materials. Possibility of obtaining solutions for strengthening fractured rocks and building structures has been studied. Study results of wastes of the Akshatau Mining and Processing Plant are presented and the possibility of using them to strengthen fractured rocks is confirmed. With the help of strengthening, it is possible to slow down processes of slacking and sloughing of rocks, to prevent ledges collapse and rocks sloughing from surface of slopes. Rock mass hardening in the weakened areas is achieved by substances injection into array cracks, which, after hardening and setting of rock, significantly increase its resistance to shear. The most widespread among hardening methods is cementation during mine workings (underground structures) in fractured rocks. Significance of obtained results for construction industry lies in the expansion and reproduction of raw material base of building materials industry through use of MMC waste (concentration tailings) and development of resource-saving technologies. © 2023, National Academy of Sciences of the Republic of Kazakhstan.
