神东矿区浅埋大采高工作面支架-围岩耦合关系及支架适用性研究
Study on the coupling relationship between support and surrounding rock and the app-licability of support in shallow buried high mining faces of the Shendong Mining Area
摘要
Abstract
Objectives To address the challenges of controlling surrounding rock in shallow-buried,high-intensity mining faces in the Shendong mining area,this study investigates the coupling relationship be-tween supports and surrounding rock structures.Methods The research combines theoretical analysis with field measurements,employing the"masonry beam"mechanical model of overlying rock to analyze the in-teraction between supports and surrounding rock in high-mining faces.Results The study examines mining pressure patterns,optimal support working resistance,and its applicability under specific conditions in the mining area.Findings indicate that the self-weight and rotational deformation of fractured roof rock masses significantly influence the dynamic load on the roof.The combined stiffness of the"immediate roof,sup-port,and floor"affects the fracture location of the main roof,reducing both the force and duration of roof pressure acting on the support.A coupling relationship between supports and surrounding rock exists,char-acterized by stiffness,strength,and stability.Conclusions A"support,protection,and mining three-factor method"is proposed to evaluate the applicability of supports.Methods such as estimating rock self-weight,analyzing measured end-of-cycle support resistance with an added standard deviation,and applying the rock beam transmission theory are used to validate the working resistance of supports.These findings pro-vide a scientific basis for support selection and applicability evaluation under similar conditions.关键词
