Study on Rock Pressure Deep Coal-seam Working Face

摘要：

The engineering examples of Donghai mine 32＃ seam left 9 working face, adopt the method combined theoretical analysis, field observation and numerical simulation, through theoretical analysis and practical investigations on the rules of roof strata activities, behavior of superincumbent strata and the distribution of abutment pressure of 32＃ seam left 9 working face, obtain various parameters of roof activity on this working face, range of behavior of superincumbent strata and characteristics of abutment pressure distributions, provide reference for surrounding rock control in coal face when the same coal mine of LongMay MINING GROUP CO.LTD goes deeper mining.

关键词： roof strata activities behavior of superincumbent strata abutment pressure numerical simulation
