Abstract

A detection method for monitoring mountain slippage and mine earthquake geological hazards. The problem of signal hysteresis and inaccurate information data in the existing monitoring and judging methods of mine earthquakes, micro earthquakes and mountain slips is solved. It is characterized in that a certain number of inspection wells (7) with built-in steel casings (8) are drilled in the monitoring area, and the controller (3) connected with the ground control measuring instrument (1) and the pusher (4) is placed in the In the inspection well (7), several magnetic sensitive sensors (6) reliable on the steel casing (8) are symmetrically connected under the pusher (4) through the support arm (5), and the controller (3) controls The pusher (4) fits several magnetic sensors (6) on the inner wall of the steel casing (8), and the ground control measuring instrument (1) continuously measures the stress change information at the magnetic sensors (6). It has the characteristic of using ferromagnetic properties to reflect changes in ground stress.

Description

Technical field:

[0001] The invention relates to a microseismic geological detection technology, which belongs to a detection method for monitoring mountain slippage and mining earthquake geological disasters. Background technique:

[0002] With the continuous changes in nature and the continuous exploitation of underground mineral resources, some mountains have slipped, and the geology is also constantly changing, and mine earthquakes and micro-earthquakes often occur. At present, there are many methods for predicting and judging mine earthquakes, micro-earthquakes or mountain slips: deep well seismometer measurement, electromagnetic wave earthquake precursor observation, manual observation and brush rod detection, etc. However, the deep well seismometer measurement can only have detection signal output when vibration occurs, and has the disadvantage of hysteresis and passiveness. The effect of electromagnetic wave earthquake precursor observation is not obvious in mine ear...
