Abstract:Based on the observation task of mine pressure in the 103 fully mechanized mining face of the Dayu coal mine in Shanxi Province, three methods of monitoring prediction, numerical simulation, and laboratory inspection were comprehensively adopted. The on-line resistance monitoring system of the support was arranged to analyze the distribution of support force; and the numerical value of the overburden on the top plate was established. The model simulates the movement and destruction of various rock layers in the working face; the physical and mechanical tests of coal and rock provide the basis for the classification of the roof. Through the above means to explore the mine the first mining face mining pressure law, to provide a basis for a reasonable choice of coal mining parameters, support methods and roof management methods.
