摘要：The use of cement support is being currently introduced during drivage. The correct, competent choice of grouting mortar formulations according to mining and geological conditions and their timely use can reduce unproductive labor, time and money, increase productivity and timely commissioning of the mine. An analysis of chemical composition of grouting mixtures using coal and waste rock required for their production was carried out using IR spectroscopic, chemical and X-ray fluorescence analyzes.
