Research on Heaving Floor Mechanism and Control Technology of Soft Rock Floor in Hengyuan Coal Industry
摘要
Abstract
Aiming at the difficult problems of large deformation amount,long duration,and high governance difficulty of heaving floor in weakly cemented soft rock roadways,taking the heaving floor governance project of soft rock roadways in Hengyuan Coal Industry as the basis,methods such as on-site actual measurement,surrounding rock mechanics characteristic testing,theoretical analysis and so on are adopted to systematically reveal the deformation characteristics and evolution mechanism of heaving floor of soft rock roadways,classification control strategies for heaving floor and a coupling technology system of"surrounding rock pressure relief+collaborative support"are proposed,and key support parameters are optimized.The on-site industrial test results show that after implementing this technology,the maximum deformation amount of the roadway heaving floor is controlled within 60 mm,and the deformation of heaving floor is effectively curbed.The research results provide theoretical basis and technical support for the heaving floor governance of weakly cemented soft rock roadways,and have significant engineering application value for ensuring safe and efficient excavation of deep roadways in coal mines.关键词
