Abstract Based on the mining needs of Taichang Mining Industry of Yangquan Mining Group, blasting parameter was optimized, which improved advancing rate and reduced advancing cost. according to the mining condition of Taichang Mining Industry, parallel cut and oblique cut were analyzed and compared, similar parallel cut was more adaptable to the mine. Blasting parameters were optimized based on similar parallel cut, the result showed that unit consumption of explosive and detonator reduced by 13% and 5% separately, blasting hole utilization rate and the rate of hole marks were improved by 24% and 205%, the cost of roadway advancing reduced 239.47 RMB/m.
