Presplit blasting used in surface coal mines is different from that of other openpit mines. The best presplit results will be achieved from the surface coal mines with horizontal coal seams or having remarkable weakness plane in the contact position of coal and rock, as long as explosive charge is concentrated at the bottom of hole .

This Bureau of Mines report looks at the use of millisecond delays in blast design and their effect on the resulting ground vibrations and airblast. A total of 52 production blasts were instrumented and monitored at a surface coal mine in southern Indiana.
Blasting began in 2007 at the Premium Energy mine less than a mile to the south of their home; the project was part of the King Coal Highway, a massive coal mining and highwaybuilding project that is still incomplete. The Premium Energy blasts came roughly three or four times per week in 2007 and 2008, according to the Kirks, and continued ...
BLASTING IN SURFACE COAL MINES Blasting overburden and coal in open pit mines is still considered to be an art. Even though much research has been done in areas related to surface mine blast design and anal ysis, very little of this research seems to have been applied in blasting practice.

Blast mining is a minigame, which grants Mining and Firemaking experience. Participating in the minigame requires favour with the Lovakengj House. Blast mining requires dynamite, which is made from volcanic sulphur, juniper charcoal, saltpetre, and a pot, then adding a ball of wool to the resulting dynamite pot.
