Based on specific situation in Yinyan Tin Mine during the transition of caving to cut?and?fill stoping, theoretical study was conducted on the safety thickness of isolation layer by using thickness?to?span ratio, the simplified Timoshenko beam theory and Protodyakonov′s theory. After that, the minimum thickness of isolation layer was verified by means of numerical simulation. The study results are of great signification to underground safe production.
