Abstract

The invention provides an experimental apparatus and method for static-pressure rock impact tunnel destroy. A static-pressure loading device and a dynamic-pressure loading device are respectively used for experiments on a rock test piece; dynamic-pressure loading experiment can be carried out under static-pressure loading conditions; so the technical problems of low safety performance, an incomprehensive experimental scope and incapacity of perfectly simulating actual conditions in the prior art are overcome. The experimental apparatus and method provided by the invention can safely and accurately carry out rock impact tunnel destroy experiments; and the experiments have good repeatability and better accord with deep mining engineering conditions of an actual mine.

Description

technical field [0001] The invention belongs to the field of rock mechanics, and in particular relates to a static pressure rock impact funnel destruction experiment device and method. Background technique [0002] With the increase of people's demand for resources, the intensity of mining is gradually increasing, and the shallow resources are decreasing day by day. The mines at home and abroad have entered the state of deep resource mining one after another. During the mining process of deep mines, the rock mass is destroyed under the joint action of in-situ stress and impact loads such as explosions, and in-situ stress will affect the efficiency of ore mining or roadway excavation. Therefore, it is necessary to study the problem of rock impact failure under initial stress. [0003] At present, the loading methods used in the study of rock impact dynamics mainly include explosives and Hopkinson rod devices. Among them, explosives can be used in field deep rock mass blasti...
