| Abstract: | At 3102 working face of No.9 Mine of Hebi Coal Mining Group,the gas emission is 20.6m3/t.By applying cross hole drilling and extracing in a same coal seam,double-side drilling yard extracting and backward shallow borehole extracting as well as strengthening local ventilation control and monitoring system management,the gas concentration in return air is reduced to 0.6%,total volume of 5.69 million m3 gases extracted.This brings big social and economic benefits. |
