How do you blast in mining?
Solid blasting in mining is a method used for blasting in coal faces. It consists of 12 to 15 shot holes, drilled in a pattern in the coal face equal to the gallery width. Certain explosives and millisecond delay detonators are used for solid blasting.
What is BCM and DCM?
Boundary conduction mode (BCM) and discontinuous conduction mode (DCM) control strategies are widely used for the flyback microinverter. The BCM and DCM control strategies are investigated for the interleaved flyback microinverter concentrating on the loss analysis under different load conditions.

What unit is MCM?
Glossary Term: MCM
MCM is an abbreviation for thousands of circular mils, an old measurement of wire gauge. 1 MCM = 1 kcmil = 0.5067 square milimeters. A mil is 1/1000 inch. A wire 200 mils in diameter is 40 MCM.
What is toe mining?

What is ANFO mining?
ANFO (/ˈænfoʊ/ AN-foh) (or AN/FO, for ammonium nitrate/fuel oil) is a widely used bulk industrial explosive. It consists of 94% porous prilled ammonium nitrate (NH4NO3) (AN), which acts as the oxidizing agent and absorbent for the fuel, and 6% number 2 fuel oil (FO).
What is DCM and CCM?
Continuous-conduction-mode (CCM) means that the current in the energy transfer inductor or transformer never goes to zero between switching cycles. In discontinuous-conduction-mode (DCM) the current goes to zero during part of the switching cycle.
What is DCM?
Dilated cardiomyopathy is a type of heart muscle disease that causes the heart chambers (ventricles) to thin and stretch, growing larger. It typically starts in the heart’s main pumping chamber (left ventricle). Dilated cardiomyopathy makes it harder for the heart to pump blood to the rest of the body.
How many m3 are in a ton?
1.133 cubic metres
1 ton (40 cubic feet) = 1.133 cubic metres.
How do you calculate CBM?
Length x Width x Height = CBM
This is the formula used to measure your cargo volume in CBM (m³). Say, you have a carton that is 2 metres long, 2 metres wide and 2 metres high. Then, its volume is 2 x 2 x 2 = 8 m³.

What is overhang mining?
Context in source publication
phenomenon of roof beds overhanging (cantilever) behind the shield line is associated with the occurrence of strong and thick layers, which are most often sandstones or conglomerates, in the roof of a mined seam.
What is a bench face in mining?
