Blast SideCasting in Surface Coal Mines - Free download as PDF File (.pdf) or read online for free. Explosive casting is the technique used by many surface coal mines to control the displacement of overburden by means of explosive energy. The casting moves 30-80% of the overburden into the mined-out pit, while the remaining spoil is removed by draglines or other machinery.

the surface mines, blast patterns are established through trial blasts. The blast pattern proposed from trial blast often fails to achieve the required blast results.
