Rubberized explosives are flat sheets of solid but flexible material, a mixture of a powdered explosive (commonly RDX or PETN) and a synthetic or natural rubber compound. Rubberized sheet explosives are commonly used for explosive welding and for various other industrial and military applications. Rubberized explosives can be cut to specific ...
The most commonly used explosives in mining today are ANFO based blends due to lower cost than dynamite. Before the advent of tunnel boring machines (TBMs), drilling and blasting was the only economical way of excavating long tunnels through hard rock, where digging is not possible.
A mining simulator is a type of simulation used for entertainment as well as in training purposes for mining companies. These simulators replicate elements of real-world mining operations on surrounding screens displaying three-dimensional imagery , motion platforms , and scale models of typical and atypical mining environments and machinery.
PETN is a very powerful explosive material with a relative effectiveness factor of 1.66. [2] When mixed with a plasticizer, PETN forms a plastic explosive. [3] Along with RDX it is the main ingredient of Semtex. PETN is also used as a vasodilator drug to treat certain heart conditions, such as for management of angina. [4] [5]
A detonator is a device used to make an explosive or explosive device explode. [1] Detonators come in a variety of types, depending on how they are initiated (chemically, mechanically, or electrically) and details of their inner working, which often involve several stages.

The tip moves at 7 to 14 km/s, the jet tail at a lower velocity (1 to 3 km/s), and the slug at a still lower velocity (less than 1 km/s). The exact velocities depend on the charge's configuration and confinement, explosive type, materials used, and the explosive-initiation mode.
The composition of the two most common variants differ according to their use. The 1A (or 10) variant is used for mining, and is based mostly on crystalline PETN.The versions 1AP and 2P are formed as hexagonal booster charges; a special assembly of PETN and wax inside the charge assures high reliability for detonating cord or detonator.
