  • Force chains in top coal caving mining ScienceDirect

    The top coal caving mining broke the equilibrium state of the initial force chain network With the advancement of the working face and withdraw of the top coal, the strong force chains near the coal face disappeared The vertical force chains above the main roof deviated and extended laterally, and finally formed an arching force chainThis paper provides a novel rockcoal interface recognition method based on stacked sparse autoencoders (SSAE) Given their different size and hardness, coal and rock generate different tail beam vibrations Therefore, the rockcoal interface in top coal caving can be identified using an acceleration sensor to measure such vibrations The end of the hydraulic support beam is an ideal locationRecognition of rock–coal interface in top coal caving
