Precise Grouting in Multi-Bed Separations of Overburden Under Curtain Protection for Isolated Coal Pillar Recovery

Traditional overburden bed-separation grouting technology often leads to issues of grout leakage and insufficient control of surface subsidence, primarily due to its poor adaptability to specific mining conditions such as isolated coal pillar recovery, the development of stratigraphic faults and fra...
