Deep granite rock burst positioning measurement system and deep granite rock burst positioning measurement method based on WSN

Abstract

The invention provides a deep granite rock burst positioning measurement system and a deep granite rock burst positioning measurement method based on WSN. The deep granite rock burst positioning measurement system comprises a plurality of sensing stations, a wireless router set which is electrically connected with the plurality of sensing stations, a coordinator, a gateway, a server and a client. The sensing station comprises a plurality of sensing nodes which are arranged on a tunnel in the rock body of granite. The sensing nodes are used for measuring rock body surface displacement, rock body surface pressure, rock body deep displacement and rock body deep temperature / humidity. The wireless router set, the coordinator, the gateway and the server are successively connected electrically. The gateway and the server are connected with the client. The wireless router set transmits data which are acquired by the sensing nodes to the server through the coordinator and the gateway. The server processed the acquired data and generates an alarm for abnormal data in a coordinate graph. Dynamic information of the rock body is monitored through a wireless sensor network, thereby measuring the position of rock burst, greatly improving measurement efficiency and furthermore ensuring safety of personnel.

Description

technical field [0001] The invention relates to the technical field of rockburst location measurement in deep rock mass engineering, in particular to a WSN-based deep granite rockburst location measurement system and method. Background technique [0002] At present, the construction of deep underground space is in the ascendant worldwide, and it has become a common trend worldwide to seek development space in the deep part of the earth. The problem of deep rock mechanics has become the focus of research in the field of rock mechanics and underground engineering at home and abroad. During the excavation and unloading process of the deep surrounding rock, the elastic strain energy stored in the rock mass will be released suddenly, resulting in rockburst phenomena such as bursting, peeling, ejection or throwing damage. The manual excavation of the underground stope destroys the initial stress balance state of the rock mass. Due to the one-way or two-way unloading, the stress o...

AI Technical Summary

Problems solved by technology

The above-mentioned invention patents are only for measuring the displacement and deformation of the deep surrounding rock under the action of high ground stress, and have not yet achieved the measurement of the mechanical properties of the rock mass and the location of the rockburst during the actual deep rock mass excavation process.
