Abstract: Based on surrounding rock stability control theory of mine roadway,according to seam formation features and space relationship of coal mining face,a FLAC 3 Dsimulation pane was established.There were two planes of mining first 1 late excavation 1 mining again and excavation first 1 late mining 1 mining again.An analysis was conducted on mining operation in No.8 seam and mining operation in No.9 seam affected to No.3093 tailentry gateway.An analysis was conducted on three aspects of adva nce support pressure,floor mining pressure and lateral support pressure affected to mining scope of No.2089 coal mining face and No. 3093 coal mining individually. The s tudy results showed that excavation first and mining second plan would have a depth of 3 m in the plastic zone of surrounding rock along roadway and roof subsidence val ue was 65 cm.The mining first and excavation second plan would have a depth of 0.5 m in the plastic zone of surrounding rock along roadway and roof subsidence value w. as 22 cm.Thus the mining first and excavation second plan should be optimized.
