The Integrated Control Countermeasures on Floor Heave of Broken Soft Rock with High Ground Stress

摘要：

　　The floor heave is one of the key issues of surrounding rock stability control during the deep well mining process.To solve the problem about floor heave occupying the most of roof and floor convergence deformation,the author analyzed the engineering geological conditions of broken surrounding rock and the floor heave features in PanEr Coal Mine East 2 mining area when it through the fault zone with high pressure.It pointed out that we should make full use of the reinforcement of the roof and laneway”s side to limit the deformation of the floor,and make use of overbreak,prestressed anchor cable,bottom comer bolt,deep hole grouting and backfill as direct bottom control countermeasures.
