Zusammenfassung: | The invention discloses a different-scale crushing coal rock compression carrying experiment method under the effect of variable pre-tightening force. The method mainly comprises the following steps of putting a fixing device onto the bottom loading axis of a rigid experiment machine; determining the installation position of a slide moving device according to the coal rock body scale parameter; performing monitoring device debugging and horizontal pre-tightening force applying according to the designed coal rock body anchoring parameter; performing crushing coal rock body material charging andfilling and leveling in a carrying box; performing a single-shaft compression carrying experiment on the crushing coal rock body under the effect of the pre-tightening force; analyzing the collectedhorizontal and vertical direction data of the crushed coal rock body. The method has the characteristics that the operation is easy; the steps are reasonable; the experiment is precise, and the like.The carrying characteristic |
