Abstract In order to ensure the safety during crossing the four abandoned roadway in the mining of No.18206 Face, the method of anchor net cable composite support by way of supporting scheme optimization design. At the same time, Erection of wood cribs were carried out on the roof. Through the digital equipment support dynamic pressure observation before and during the running of the abandoned roadway, the changes of working resistance and initial support force were got by real-time collection of dynamic pressure data for analysis in different stages. On this basis, timely support was adopted on roof support to ensure the safe construction.

Key words： mining face abandoned roadway support reform optimization
