Application of Water Content Detection Scheme of Coal Rock Layers in Roadway Excavation
In view of the low accuracy of traditional water content detection technology of coal rock layers in detecting the spatial location of hidden water sources,water damage accidents are easy to occur in coal mines,which seriously affects the safe and efficient production of coal mine enterprises,the method of parallel electrical method+double-roadway three-dimensional resistivity inversion technology was used to investigate and analyze coal mine hydrogeology and engineering geology.Through the analysis of the basic principle of electrical detection,the overall design of water content detection scheme of coal rock layers,the research on the data processing of two-roadway three-dimensional resistivity inversion and the application analysis of water content detection scheme of coal rock layers,the research on water content detection of coal rock layers has been completed.By comparing the detection results of coal mine A with the subsequent production data and records,it was found that the accuracy rate of water content detection data of coal rock layers reached 98%,which met the relevant requirements of coal rock water content detection.
