A fuzzy method for selecting underground coal

2012-11-30  One of the crucial decisions affecting productivity of the mine is the mining method selection. Longwall mining is quite common in underground coal mining, and it allows the use of mechanization. As application of mechanization increases, production also increases and the number of workers decreases. Thus, the organization of work is easier, and the number of accidents decreases

Activated carbon, what is activated carbon,

Activated carbon (also called activated charcoal, activated coal or active carbon) is a very useful adsorbent. Due to their high surface area, pore structure (micro, meso and macro), and high degree of surface reactivity, activated carbon can be used to purify, dechlorinate, deodorize and decolorize both liquid and vapor applications.

Selecting a CCD Camera for Spectroscopic

CCD detection systems specifically designed for spectroscopy are sometimes referred to as cameras. However, they incorporate CCD sensors which typically have larger pixels and are longer than the CCDs used for imaging applications. Imaging CCDs typically are 6 mm x 4 mm with pixels smaller than 10 μm square. Spectroscopic CCDs are often 25 mm
