Method of monitoring rock pressure and test arrangement for carrying out the method |
摘要 |
Working points in coal mining which are in danger of rock burst require constant monitoring. First the rotatability of a tube inserted into a drill hole and subsequently the cross-section or the passage of the deformed tube are determined via sounding rods. To this end, test bores for the accumulation of drill cuttings are made parallel to the drill-hole sounding while avoiding bench tests.
