Evaluation of Control Effect of Confined Water Hazard in Taiyuan Formation Coal Seam Mining in Huanghebei Coalfield

The shallow-layer resources in the Huanghebei Coalfield have been depleted, and deep coal seam of Taiyuan Formation (lower group) is main continuous resource mining at this stage. With annual increase depth, exploitation lower groups being met with influence high ground stress, water pressure, temperature, strong disturbances, as a result which threat inrush particularly serious. Based on grouting data coalface floor aquifer, paper proposes an evaluation method for control rushing into floor. By comparing test mine electrical exploration through ArcGIS, results show that pressure threshold based ArcGIS twice reconstruction layer optimal solution. research can provide reference prevention group Coalfield.
