Abstract
In the process of coal mining,the development height of overburden"two zones"(collapse zone and water-conduc-ting fissure zone)is an important parameter for the prevention and control of water hazards in mines,and it is of great signifi-cance to accurately predict and control the development height of the"two zones"to ensure the safe production of mines and to prevent water hazards accidents.Taking the 2207 comprehensively mechanized working face of No.2 coal seam in Qingwa Mine as the research object,UDEC numerical simulation software was used to construct the model and carry out the excava-tion simulation to analyze the damage of overburden rock at different advancing distances of the face,and measure the height of the overburden rock development of the two zones after the mining of the comprehensive mechanized working face,and through simulation,the height of the collapse zone ranging from 13.7 to 16.2 m,and the height of the fissure zone ranging from 46.2 to 50.7 m were obtained.In order to verify the accuracy of the simulation results,empirical formula calculations and in-site measurements were carried out,showing that the numerical simulation results are basically consistent with the empirical formula calculations and in-site measurements.关键词
