Reasonable Mining Deployment Adjustment of Feitian Coal Mine

For the difficult gas governance and excavation and unreasonable regional outburst prevention measures in a partition area of Feitian Coal Mine, through rational argumentation of mining sequence and regional outburst prevention measures, the first layer is changed to 16^# coal seam from the original 6^# coal seam; mining sequence is adjusted for "uplink within groups and downlink in groups " way. The heading face in the first mining layer used the through beds hole to pre-drainage strip coal seam gas; the mining face used bedding drilling to pre-drainage strip coal seam gas.After the adjustment,the extractive deployment tends to be reasonable.
