Impact ground pressure simulation device and wireless data acquisition system

Abstract

The invention discloses an impact ground pressure simulation device and a wireless data acquisition system; the device includes a test machine cavity design and a wireless data monitoring system design; the device is characterized in that the test machine cavity includes an opening mechanism, a partial opening surface, an all opening surface, a test machine cavity and a non-transformation pressurechamber; the wireless data acquisition system includes a wireless stress acquisition device, a wireless vibration recording device, a wireless high-speed camera, a wireless high-speed camera, a wireless high-speed camera, a host, a server, and a wireless transmission device. The device has the original design of the pressure chamber opening surface and the opening mechanism. The two high-speed cameras are arranged at two sides of the vertical direction of the opening surface horizontally and are located at a distance 2 m away from the two sides of the pressure chamber; one high-speed camera is arranged in a manner directly facing to the opening surface, and is 2 m way from the surface, so as to record the impact ground pressure process. In the process of implementing the experiment, people are not needed in the field, and thus the safety of the people is ensured.

Description

Technical field [0001] The invention relates to the technical field of mine safety engineering. In particular, it involves laboratory simulation of rock bursts. Background technique [0002] Rock bursts generally occur in mining projects and underground projects, causing serious economic losses, casualties, and severe social impact. It is one of the industrial disasters that the society and the government pay attention to. [0003] Generally speaking, according to the stress of coal (rock) masses, mining induced rock bursts can generally be divided into three types. Among them, coal (rock) mass pressure bursts are the most common form of occurrence in the mining process, accounting for about 80 in total. %, such as Liaoning Fushun, Fuxin, Shandong Xinwen, Kailuan, Tangshan, Sichuan Tianchi and other coal mines, are the key issues in the study of rock burst. Academician Qian Qihu of the Chinese Academy of Engineering pointed out that a severe rockburst is like a small earthquake, ...

AI Technical Summary

Problems solved by technology

However, due to the rapid and violent characteristics of its occurrence, it is difficult to capture the disaster scene, and it is usually difficult to simulate it in the experimental situation, resulting in less relevant research

[0005] In summary, the occurrence characteristics of rock burst make it difficult to fully capture the whole process of occurrence in experiments and on site, resulting in a low level of rock burst simulation and prediction prevention technology
