Abstract: In view of the frequent occurrence of gas accidents in coal mine production in China, combined with the engineering
background, this paper obtained the height of caving zone and fissure zone of overlying strata in stope from empirical formula and
numerical simulation. On this basis, high-level boreholes were designed and constructed to extract gas from fracture zone. The
results showed that the extraction effect was stable and the problem of large gas emission from adjacent strata was solved.

Key words: caving zone; fissure zone; high-level borehole; gas extraction
