[0002] The downward sublevel filling mining method refers to sublevel stoping from top to bottom, constructing a false roof of the next sublevel during stoping of the previous sublevel, and stoping the next sublevel under the protection of the false roof. This method is suitable for ore bodies with stable rock. When the ore body is inclined, if the above method is used for mining, the empty area needs to be filled first, and the filling body on the false bottom is used as the roof of the next sublevel, and then the subsequent mining work is carried out. In order to ensure the smooth progress of the mining work, it is necessary to ensure the high stability of the roof, and the stability of the roof is directly affected by the deformation amount of the filling body. Therefore, it is necessary to monitor the deformation amount of the filling body during the filling process.
