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 invention relates to a water disaster real-time grading forewarning method and system based on mine electric method monitoring. According to the water disaster real-time grading forewarning methodand system, monitoring data are processed automatically in real time through 3D-resistivity inversion; according to the real-time changing situation of the coal measure stratum resistivity obtained through inversion, grading judgment is conducted on the water gushing risk of the working surface automatically, and grading forewarning information is sent automatically in real time; and automation and intellectualization of water disaster forewarning of the working surface are achieved, monitors can conveniently master the development condition of a water-conducting channel in the stoping working surface in real time, the water gushing hidden danger is checked timely, and thus the powerful guarantee is provided for life safety of miners and property safety of the mine party.

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...
