Abstract
The problem of roof water damage in Datong Coking Coal No.1 Mine seriously affects the normal production and personnel safety of the coal mine.In order to accurately evaluate the water-richness distribution characteristics of the roof aquifer,the downhole network parallel electrical method technology system is used to detect the height of the water conducting fissure zone in the Permian Shihezi Formation aquifer.Based on the sediment control method,the planar distribution and lateral spatial distribution characteristics of the aquifer are analyzed,and an evaluation system is constructed for four key indicators:sedimentary environment impact index,sand mudstone interlayer ratio,sandstone thickness,and geophysical water body richness anomaly index.The Analytic Hierarchy Process(AHP)is introduced for weight allocation to draw a comprehensive zoning map for evaluation.The results show that the evaluation system can accurately divide the water-richness areas of the roof aquifer,and effectively verify them through the actual measured data of mine water inflow.The evaluation results have relatively good consistency with the actual pumping test results.关键词
