Investigation on Formation Mechanism of Separated Layer of Rock Covering and CalculationMethod of Separated Layer

ZHANG Jianquan et al.  
A theoretical investigation was carried out on the mechanical structure and conditions due to separated layer of rock covering based on the physico mechanical properties and structure of strata. The pos sible position of separated layer of rock cover was analyzed and the method for calculation of maximum sepa rated layer was suggested, which gives a guidance to the grouting in separated layers of rock cover to reduce the subsidence in the field.
