Experimental method of simulated impact type rock wings

摘要

In an experimental method for simulating the impact type rock blades, comprising the steps of fabricating a rock test sample having a through hole or a half bore, comprising the steps of loading the three directions of the initial static load stress to the rock test sample, rocks the the disturbance load to the test sample is loaded 0.5-10 minutes, a step of observing whether delamination on the inner surface of the through hole or half hole rock test sample appears, the peeling phenomenon on the inner surface of the bore appeared, in the case where and it is further disrupted and the static load to the process of the fracture was observed and recorded, in the case where it did not appear, until the rock test sample enters the process of destruction, to be loaded into rock test sample improves stress value, or continue repeating the experimental procedure to improve the disturbance load strength, and to process the observation and recording of the destruction, the simulated impact type rock comprising the steps of terminating the impact rock splashes experiments, experimental methods of wings. According to the experimental method, it is possible to induce rock wings phenomenon rock test sample success under the action of the disturbance force. Also by studying the mechanism of rock wings phenomena rock test sample to determine the basis for progressively understand and recognize the nature of the actual rock wings phenomena.
