Research on Rock Movement Observation Technology for the 3306-1 Filling Working Face
The surface subsidence caused by coal mining poses a threat to the ecological environment and property safety of mining areas,and has a certain impact on the safety of downhole mining.In order to study the surface movement,deformation,and impact on surface buildings caused by filling working face mining in mines,a surface movement and deformation observation station is established in the mining area.Through surface deformation monitoring,the surface deformation law caused by downhole mining is studied,and accurate prediction of future surface movement and deformation is made.Key data on the impact of filling mining on surface movement are obtained through observation,statistics,and analysis of the surface movement angle and deformation value of the working face.The maximum subsidence value of the monitoring point is 58 mm,and the maximum lifting height of the"abnormal bulge"in the area is 76 mm.This lays the foundation for studying the surface movement and deformation laws under the condition of paste filling mining technology,and helps to provide technical basis for the wall deformation and damage of surface buildings.
