   This paper addresses the monitoring results in the maingate No. 080 5253 at the Paskov Mine, in the Czech Republic. In the main longwall gate in question, the convergence of the mine affected by longwall mining 080 210, movement from loosening of the rock layers using extensometers, and the load steel frame construction reinforcement by dynamometers is monitored. In addition to in-situ measurements, research laboratory measurements were carried out to evaluate the influence of geological conditions, based on the RQD parameter of boreholes drilled before the extraction. The results show that geology, the character of the overlying rocks, and rock stress ratios play important roles in the effectiveness of the combined rock bolt and steel frame supports.
   The effective action of the reinforcements also shows significant adverse effects on floor lift, and these factors are reflected in the extension and retraction of anchors in the overburden and significant deformation of the profile.
