Problems solved by technology

[0002] At present, there are not only various types of sensors for stress-strain detection in engineering, but also each has its own characteristics and scope of application. Monitoring and forecasting instruments are rare, especially the real-time automatic monitoring of mining stress changes inside the coal (rock) mass in coal mines is almost blank. 1. During coal mining, there is still a lack of reliable and effective real-time automatic monitoring and forecasting equipment for safety accidents caused by changes in the internal stress of roadway surrounding rocks and coal pillars, etc.

Abstract

The invention relates to a stress monitoring device that includes stress sensing unit made up from stress transforming structure, information transforming structure, scanning driving structure and location restricting structure and information gathering processing unit. It is a convenient, high accuracy, and could monitor the inner stress of the rock mass in real time, and could automatically tele-monitoring. It could be widely used in exploiting coal mine, construction, irrigation works, road, tunnel and underground engineering.

Description

technical field [0001] The invention relates to a detection instrument, in particular a stress monitoring instrument suitable for real-time monitoring of the internal stress of rock (coal) bodies suitable for changes in mining stress inside coal roadways and coal pillars. Background technique [0002] At present, there are not only various types of sensors for stress-strain detection in engineering, but also each has its own characteristics and scope of application. Monitoring and forecasting instruments are rare, especially the real-time automatic monitoring of mining stress changes inside the coal (rock) mass in coal mines is almost blank. 1. During coal mining, there is still a lack of reliable and effective real-time automatic monitoring and forecasting equipment for safety accidents caused by changes in the internal stress of roadway surrounding rocks, coal pillars and other rock formations. Contents of the invention [0003] The invention provides a stress monitor w...
