基于广义Hoek-Brown准则的地表移动变形规律
Influence law behind ground movement and deformation based on generalized Hoek-Brown criterion
摘要
Abstract
This paper aims to address the effect of the surface movement and deformation caused by coal mining activities in Wancheng Mining.The study involves determining the rock mass mechanical pa-rameters of Wancheng Mining based on the generalized Hoek-Brown criterion;establishing a numerical mining model of Wancheng Mining by using FLAC3D software;and analyzing the relationship between the coal mining activities and the surface subsidence in No.10 coal mine combining the observation data of the surface subsidence with the mining subsidence law of Wancheng Mining.The results show that caused by the mining in No.10 coal seam of Wancheng Mining,the subsidence coefficient is 0.81,the horizon-tal movement coefficient is 0.26,the tangent value of the main influence angle is 2.07,and the mining influencepropagationangleis79°.The findings of this study can provide a basis and reference for the mining design,coal pillar protection,preparation of operational procedures,surface structure protection,ecological restoration,and geological hazard management in coal mines with similar mining.关键词
