The LLL is a world-class surface and underground facility located approximately 60 miles southeast of Pittsburgh, Pennsylvania. The FSF is constructed to simulate a U.S. coal mine entry and crosscut. The main tunnel is 46.6-m-long and the crosscut is 12-m-long. The entries are 2.2-m-high and 5.5-m-wide.
In the second stage, coal from the hopper enters the conveyer belt through the funnel-like structure. A series of conveyor belts (refer to Fig. 2) take the coal to the raw coal silo from where coal is fed into pulverizing mill. The length of the conveyor belt is 80 m, and it travels at a speed of 1 m/s. It is important to detect the foreign ...
