The steel formwork is arranged on the support, and the support is divided into an upper support, a middle support and a lower support. The upper support is movably connected to the front end of the middle support, and the lower support is movably connected to the rear end of the middle support. The upper lifting oil cylinder is arranged between the middle support and the upper support, and the lower lifting oil cylinder is arranged between the middle support and the lower support. The utility model adopts a steel structure wall body composed of a support and an oil cylinder, and realizes the filling retaining wall of the mine through the upper lifting oil cylinder, the lower lifting oil cylinder and the telescopic support. The utility model has high structural strength, is easy to operate, is convenient to install, is convenient for underground workers to operate, shortens the preparation time of filling work, can be reused, and reduces the filling cost.

When protecting the mine slope, if completely using concrete masonry, the distribution of vegetation is limited during vegetation restoration. If using stone cage structure for protection, the protection strength will be greatly reduced. Therefore, a composite retaining wall structure needs to be designed to ensure the stability of the mine slope protection and not to affect the growth of vegetation restoration.
