Abstract: Based on engineering geological conditions thr ough different resemble material simulated experiment on different overhead caving schemes, it is proved that for monolithic overhead forced caving to reduce collapse distance at the first time in the working face is feasible. The study results indicate that it is possible to realize the continuously mining, and eliminate the hidden trouble caused by outstanding top of big area. Meanwhile, the influence of face adva nce on overhead and regularities of underground pressure phenomenon are revealed under conditions of thick loam of the earth's surface layer overburden on shall ow buried coal seam with individual prop. The study results provide the reliable basis for Nanliang coal mine to realize continuously mining under conditions of mono-hydraulic pressure pillar long working face.
