At present, the isolation and sealing work of the goaf area in the filling working face interacts with the front coal mining work. When filling the coal mine, the sealing and isolation speed of the area to be filled is slow, the labor intensity is high, and the efficiency is low, which restricts the efficiency of the paste filling coal mining working face. An important factor in production; when performing isolation and sealing work in goaf areas, coal mining equipment such as shearers and scrapers must be stopped. However, the structural form and basic functions of the existing paste-filled hydraulic supports cannot be effectively adapted to coal mining. Requirements to be carried out simultaneously with filling.
