Apr 07, 2010· Coal dust is highly combustible (and the smaller the dust particles in any given volume of air, the more explosive potential exists), and there are lots of ways to create it: the mining machines create clouds of dust as they attack the walls, the conveyors carry dust through the mine, and vehicles stir up dust on the floors, to name just a few.
The claymore is one of the most insidious weapons ever devised, responsibile for millions of limbs lost in the Vietnam War. This video will show you how to make a much safer prop version out of cardboard and papiermache to use in a film that still looks quite realistic.

Thousands of products are made with coal or coal byproducts, including aspirins, soap, dyes, solvents, plastics, and fibers such as rayon or nylon. Coal is an important ingredient in production of products that require activated carbon, carbon fiber or silicon metal.
There were also three basic types of coal mining operations that often dictated how the surface buildings were arranged. A deep mine would have shafts into the earth and Aframe hoists to transport material and men to and from the working portions. There should be at least two Aframe hoists.
he basic 4 x 8 layout has become something of a model railroading tradition. The concept behind it is pretty simple: 4 x 8foot sheets of plywood are readily available at lumber yards and homeimprovement stores, and with a minimum of carpentry skill, most anyone can build some sort of leg structure to support one, making for an easy train table.
Drilling Methods Used in Coal Mines Posted by: Jess Peláez in Drilling, Drilling and Drill Results For coal deposits, like most other minerals, drilling is a key to identifying in detail the grade and size of the resource, both prior to mine development, and during operations.
Building a coalhauling model railroad. Although Tony Koester built the Coal Fork extension as an addition to his Allegheny Midland, this layout would make a great model railroad by itself. Along with the track plan, you'll see how to build benchwork, get tips for handlaying track, learn how to build appropriate scenery and structures, and more.

visited to obtain data on their mining practice or design. Commodities included coal, sandstone, and limestone. Based on the visits, five case studies were developed to represent typical mining methods and effective ground control practices used in eastern surface mines. Benching was found to be a common technique to reduce the overall highwall slope angle.
Transportation networks in the region also restricted the growth of coal mining. Turnpikes proved too expensive for the coal trade and the James River and Kanawha Canal failed to make necessary improvements in order to accommodate coal barge traffic and streamline the loading, conveyance, and distribution of coal at Richmond's tidewater port.
