The invention discloses a magnetic suspension ring ruler roadway deformation monitoring and early warning device which comprises a detector body. The detector body is provided with an electromagneticcoil, an electromagnetic casing pipe, a measurement point fixing head and a controller. The electromagnetic coil spirally sleeves the surface of the electromagnetic casing pipe, and a central casing pipe is arranged on the internal central line of the electromagnetic casing pipe; the surface of the controller is provided with a main switch, an early warning lamp, a displacement displayer and a coil switch; a deviation calculation and overflow alarm program is set in the controller. An actual testing result indicates that the magnetic suspension ring ruler roadway deformation monitoring and early warning device is firm and stable in structure, the identification and calculation speed of the controller is high, electromagnetic coil positioning is accurate, and it can be completely achieved that the roadway deformation monitoring device uses a graduation ruler as a measurement unit and uses an elastic soil as a location survey element and is suitable for popularization and application.
Description
technical field [0001] The invention relates to the technical field of mine roadway construction, in particular to a magnetic suspension ring ruler roadway deformation monitoring and early warning device. Background technique [0002] In recent years, the shallow and easy-to-mine mineral resources have been nearly exhausted; deep mining is an inevitable trend of underground mining. However, with the increase of mining depth, high ground stress will bring great harm to the stability of the roadway. Therefore, accurately reflecting the deformation of the roadway and predicting the deformation and failure of the roadway have important reference value for the selection of the roadway support scheme. Usually, due to the problem of the reference point in the monitoring of roadway deformation and displacement, there is a large error in the measurement data, which brings great difficulties to the later maintenance of the roadway. [0003] The invention adopts the principle of elec...
