As a typical geological structure, the fault often threatens safe mining of coal mines. In order to investigate permeability evolution significant normal under disturbance thick seam footwall and propose scientific reasonable (rock) pillar retention plan, this paper took YinJiaWa Fault (YJW Fa), large fault, in Fucun Coal Mine, Shandong Province, China, as research object, conducted coupled fluid solid simulation study on using COMSOL Multiphysics, based revealed data rock mechanical...
According to the data of draining test, we simulated Ordovician limestone aquifer seepage field by MODFLOW module GMS (Groundwater Modeling System).After numerical simulation model building, successfully formed test and dynamic changes in water level recognition inspection.The results reflect that lateral connectivity hydraulic connection fissure crevasse is weak aquifer.The study provides theoretical base practical references for safe mining No.11 coal seam which threatened confined water.
Mine water disasters are one of the main threatening safe mine operations. If a fault becomes guide channel, it often causes serious inrush accidents in mining. Therefore, accurate evaluation hydraulic conductivity is very important for prediction and prevention disasters. To prevent control ensure mining coal seams presence faults, this paper takes F22 Jinqiao Coal as an example; proposes three highly applicable methods based on analysis water-rock stress, difference hydrochemical...
