Embodiment

[0031] The monitoring data collected by the mine electrical monitoring system are generally potential or potential difference. Through three-dimensional resistivity inversion processing, three-dimensional resistivity data that can more directly reflect the electrical distribution of coal-measure strata can be obtained. During the development of the aqueduct, the resistivity of the area affected by it will gradually decrease. By analyzing the real-time changes in the resistivity of the coal-measure strata obtained from the inversion, the development of the water-conducting channels can be effectively judged, so as to achieve the purpose of early warning of the risk of water inrush.

[0032] Such as figure 1 As shown, the embodiment of the present invention provides an automatic real-time graded early warning method for water hazards in the working face based on mine electric monitoring. early warning.

[0033] Firstly, based on the geological data of the mining face, a three-...

Abstract

The present invention adopts three-dimensional resistivity inversion to automatically and real-time process the monitoring data, and according to the real-time change of the resistivity of the coal-measure strata obtained from the inversion, automatically classifies and judges the risk of water inrush at the working face, and automatically and real-time sends the classified early warning information, The automatic and intelligent early warning of water damage in the working face is realized, which is convenient for the monitoring personnel to control the development of the water guide channel in the mining face in real time, and timely check the hidden dangers of water inrush, which provides a powerful guarantee for the life safety of miners and the property safety of the mine Assure.

Description

technical field [0001] The invention relates to a method and system for real-time early warning of water damage, which belongs to the technical field of mine mining, in particular to a method and system for real-time graded early warning of water damage based on mine electrical monitoring. Background technique [0002] Water hazards in the working face are often induced by containing and conducting water geological structures. Water-containing and water-conducting geological structures will not cause water inrush accidents under static conditions, but under the influence of mining activities, due to changes in the distribution of in-situ stress, structural fissures in rocks will expand or new ruptures will occur. It will further develop into a water conduction channel between the coal seam and the aquifer, which will lead to the occurrence of water damage in the working face. Compared with coal-measure strata, the water-bearing and water-conducting geological structures gen...
