[0002] The backfill mining method has been widely used in underground mining of metal mines, and the safe, efficient and cost-controlled backfill retaining wall construction method is still the direction of the industry's efforts. Due to the high danger of goaf areas, workers have poor safety when constructing backfill retaining walls in goaf areas. Once a safety accident occurs, it will seriously affect the normal production of the mine. Reducing the time required to construct backfill retaining walls means that workers are exposed to dangerous environments for a shorter time, which has significant safety significance. In addition, the backfill retaining wall construction method should be simple and convenient, otherwise the labor cost and material cost investment will be large, which is not conducive to the mine to control the backfill cost.
[0003] Traditional retaining walls used for underground filling in mines mainly include ordinary wooden retaining walls, brick retaining walls, concrete retaining walls and flexible retaining walls. These retaining wall processes are relatively complex, with long construction periods, and workers are exposed to the goaf for a long time, which is highly dangerous. The cost of retaining wall materials and labor is high, which leads to increased filling costs. At present, some retaining walls filled with mold bags have also appeared. After pouring the filler, it is difficult for such retaining walls filled with mold bags to achieve complete active connection under the action of gravity. There are often gaps at the connection point, which is prone to leakage. Utility Model Content
