Abstract Based on the difficult mining of isolated island in 10-211 working face of No. 10 coal seam in Mugua Mine, the stress in different recovery mining was analyzed by theoretical analysis and numerical simulation. The analysis showed that the influenced scope was 8~9 m mainly affected by goaf side stress, stress released in mining, with non-significant effect, periodical pressure was 40~45 m, pre-support 4~5 m in isolated island mining. The mining stress law of Mugua Mine was got, which provide theoretical data for the similar isolated island mining.
