Holes for blasting vary in size from an inch to several inches depending on the application. Depth will vary across applications as well. The effective diameter of a blast will depend on the size of the charge, the depth in which it is placed and the type of material that is being blasted. And all of this will vary as widely as the application. In commercial mining applications, it is unusual to make a single hole and pack a single charge to make a shot. This ups the challenge to estimate the amount of material that will be displaced, but the professionals who do this blasting can make these estimates.

Do blackholes have a diameter Why or Why not?

Yes, black holes have a diameter, which is referred to as the event horizon. The event horizon is the region beyond which nothing, not even light, can escape the immense gravitational pull of the black hole. This diameter can vary depending on the mass of the black hole.


What is the length of a black hole?

The diameter is usually considered the diameter of the event horizon. The diameter of this event horizon is directly proportional to the black hole's mass.

How do you beat level 26 on boombot 2?

Blast a hole in the third column left of the exit, without setting off the TNT. Then blast your bot over into the space between the second and third columns, and as he is falling toward the hole, blast the second column a little higher than the hole, pushing him right and over into the exit.
