Jet Fan Ventilation in Very Deep Cuts - A Preliminary Analysis

Future coal mining systems will be able to cut from crosscut to crosscut where advances could exceed 100 ft. However, limitations arise when ventilating such mining systems. In deep advance mining, there would be no workers at the face to advance ventilation tubing or curtain manually.

Occurrence of phosphorus minerals in Australian coal seams ...

They sometimes occur alone, but in many cases are intimately associated with kaolinite and possibly quartz. Later-formed veins filled with either apatite or aluminophosphate minerals also occur in some coal seams, particularly in the more vitrinite-rich sub-sections. These typically cross-cut the pore-filling accumulations.

Fluid–Solid Coupling Characteristics of Gas-Bearing Coal ...

Chinese coal seams are characterized by high gas content and low permeability. The permeability of coal seams should be improved to achieve maximum extraction of coalbed methane. This study explores how coal and gas behave when subjected to hydraulic slotting. A fluid–solid coupling experimental system of gas-bearing coal subjected to hydraulic slotting was first established. Then, the fluid ...

Scottish Coal v Royal and Sun Alliance

Mining through a cross-cut poses a higher risk of collapse than more conventional mining methods. Scottish Coal obtained specialist advice on the appropriate support system but, as it turned out, did not follow that advice. In May 2000, the cross-cut collapsed during the mining process. Mining equipment was lost and some 29,000 tons of coal ...

7 Questions About Sample Rate Sweetwater

If the sample rate is 44.1kHz, the highest frequency that can be captured and stored is a bit less than half of the sampling frequency, or around 22kHz. Remember that the accepted standard for the human hearing range is from 20 Hertz to 20,000 Hertz or 20kHz , though in practice, most of us don’t hear frequencies that high.
