Main support types for paste filling: ZC3800/22/40D, ZC4000/16/32, ZC6000/22/43D, ZC6000/23/45D, etc.
Advantages of paste filling: Solve the problem of air leakage in goafs and eliminate hidden dangers of spontaneous combustion of residual coal; control roof subsidence, eliminate stress concentration and facilitate roof management; change the movement law of overlying strata and prevent rock burst disasters; reduce the development height of cracks in the upper and lower "three zones" and mitigate the risk of mining under confined water.
The main support body for front coal mining and the rear filling isolation support body adopt a split design. The front and rear supports are connected by pushing jacks, enabling parallel operation of front coal mining and rear filling.
