- Based on the study of cutting theory of shearer pick-shaped cutter used in thin seams, cutting tests under different fault conditions were done by using pick on the Cutting Test Bed of the Coal and Rock. The results show that: picking Cutting Torque in the coal seam and small fault interface increases with the increase compressive strength difference between the coal seam and small fault. Meanwhile, the mean increments of the cutting torque did not change exponentially, when the thickness of full fault is twice the thickness of top fault or bottom fault in the cutting tests. Through time-domain analysis and frequency-domain analysis of cutting load, it can be seen that probability density curves of pick torque obeys normal distribution in cutting coal seams and small fault. The drum speed affects load fluctuations a lot different forms of coal and rock has some impact on the load fluctuation.
