隔水层裂隙演变机理与过程研究
Evolution Mechanism and Process of Aquiclude Fissures
摘要
Abstract
Taking the Shengdong mining area shallowly buried seam mining geological condition for example, we study the dynamic mechanism and the rule of soft aquiclude fissure evolution in overlying strata under coal mining conditions. Based on the analysis that water-resisting property of weathering the top of shallowly buried seam with thin bedrock and the rule of overlying strata fissure, we establish the flat mechanics model using the difference method in thin plate theory, application of strain analysis theory, collapse with the underlying risk characteristics of elastic foundation rock. In addition, we also study the movement law of long wall face rock in shallowly buried seam with a thin bedrock, obtaining the relationship between soft aquiclude rupture distance and elastic foundation constants and different exploitation of space corresponding elastic foundation constant limit. The research can provide a theoretical basis for water-keeping mining shallowly buried seam in western China.关键词
