Experimental Research on Critical Force of Crushing and Sorting Coal Mine Gangue

Abstract:

First, The pressure test on two actual coal mine irregular and different particle sizes of coal and gangue, through the experimental data, using MATLAB software to give a graphic simulation and assumptions test of normal distribution, by the graphics and hypothetical test confirmed that coal and gangue had obvious demarcation, namely the critical force of crushing and storing coal gangue. In a coal mine as an example,and acquisiting more irregular and different particle sizes of coal and gangue were broken by static experiments and dynamic crushing experiment, using the experimental data obtained pressure distribution and pressure distribution curve equation,by equation to solve the crushing critical force FL of the size of 50-90mm coal and gangue,through mathematical and graphical analysis proved the rationality of FL,and providing a basic data for the future work.
