Enhancing Efficiency of Direct Dumping by Cast Blasting of Overburden Rocks
The article reports the modeling results on direct dumping of overburden by cast blasting. The cast factor variation as function of seam occurrence and explosion block parameters is found. Potential improvement of cast blasting to displace overburden to mined-out pit area is described. The ways of e...

| description | The article reports the modeling results on direct dumping of overburden by cast blasting. The cast factor variation as function of seam occurrence and explosion block parameters is found. Potential improvement of cast blasting to displace overburden to mined-out pit area is described. The ways of enhancing efficiency of direct dumping in gently dipping coal extraction by combination of truck-and-shovel system with direct dumping in Kuzbass are identified. |
