| Abstract: | Analyses the forming factor and feature of karst cave of the ordorician systemcalcarenite in Huaibei coal field in different times and divides the karst cave into erodecave phrealic cave, inflow cave and aquifer cave. Acording to the fracture mechanics oflayered sedimentary and reforming prosess of the cave, the auther puts foward the model of many cycle activte cause of 'formating of the carst calumar callapse in coal bearingstrata |
