Figure 3. Shear stresses in collector construction in the function of dumped material Figure 4. Shear stresses in collector construction in the function of dumped material Figure 5. Shear stresses in collector construction in the function of dumped material Figures 2 to 5, show shear stresses distribution in the massif and in the section along collector. It can be seen from these Figures that the shear stresses caused frac- ture in the collector cover. Figures 6 and 7 show vertical stresses increased with the increase of dumped material. No 1,2010. 33 MINING ENGINEERING
Figure 6. Vertical stresses in the function of load increment Figure 7. Vertical stresses in function of load increment Calculation of collector cross-section was made for construction type I (coating thickness 45 cm). Model of finite elements for collector cross-section is shown in Fig. 8. Figure 8. Numerical model for the collector cross-section No 1,2010. 34 MINING ENGINEERING
