| The main physical-mechanical properties of the coal grounds and dependence of their stable capacity on the humidity, temperature and vibration actions have been investigated. It is shown that solid characteristics of these grounds, characterized in first turn by the resistance from displacement trd and its derivations C and j, decrease under the action of temperature, humidity and vibration. Under the rise of temperature from 14 up to 40°Ñ cohesion decreases in 1.32 times and angle of internal friction decreases in 1.48-1.9 times. Ground water - saturation can lead to full waste of the solid properties (C=0, j=0). Decrease of resistance from displacement trd under the action of vibration depends on the value of amplitude 2a more essentially at range of 0.01≤2a≤0.1. At the fixed value of this sign increase of concentrated pressure (litastatic loading) lead to the growth of trd in 1.36-2 times. |
