摘要
Abstract
This article summarizes the current progress in research on borehole pressure relief from four aspects:theoretical analysis,indoor experiment,numerical simulation,and on-site application.Based on macro level(including mechanical response and failure characteristics)and micro level(crack evolution),summarize the current relevant indoor experiments and numerical simulation studies on borehole pressure relief,and point out that the essence of borehole pressure relief is the initiation-expansion-penetration of cracks between adjacent pressure relief holes;From the perspective of on-site application,it is discussed that borehole pressure relief can greatly reduce the impact risk of surrounding rock.Indoor tests of hole anchor collaborative are carried out.When the pre tension force of the anchor rod and the distance between the holes and anchors are within a certain range,the combination bodies can maximize the release of elastic performance while ensuring strength and stiffness;A prospect is made on the urgent research direction of borehole pressure relief and scour prevention,and relevant indoor experimental studies are carried out on the combination rock bodies of hole anchor under the real-time drilling condition.The phenomena of energy release in surrounding rock caused by real-time drilling of pressure relief holes are reproduced in order to reveal the collaborative mechanism of pressure relief and anchoring.The research results can provide new ideas for the development of borehole pressure relief technology in the future.关键词
