Mining of raw materials and their modification has a negative impact on the environment. During the mining and processing of mineral raw materials (coal, oil, ore), solid, liquid and gaseous wastes are created. The production of waste is linked to the mining site, respectively production. Many of the negative phenomena can be minimized or even eliminated by using appropriate technologies and work procedures. At the present, the search and secondary use of large-volume waste is gaining more and more importance. In the underground, possibilities are offered in the field of fire prevention, closing and disposal of mine works, fill and so on. A thorough assessment of the criteria and their compliance during implementation creates a basic prerequisite for the use of underground waste with the verification that there will be no release of hazardous pollutants from the source of harmful substances as well as that the elements of the environment will not be endangered and the use of waste will be safe.
