index distinguish structural zone and upper limestone ordowiku determination, upper zones fill limestone ordowiku based on reservoir depth of residual coal more than 300 m, according to the indexes of unit value of structural differentiation borehole water qunderground drainage borehole test value q and the value penetration test are divided into three types of upper zones fill limestone ordowiku; hydrophobic zone fill thin waterproof stanza completion and zone added in water.waterproof zone filling may be directly used as the waterproof layer; a thin metal zone filling may be used after correction to the weather zone completion by spoinowanie.index to distinguish structural is obtained in a conventional way is relatively simple hydrological tests and to obtain and easy-to-use by field staff.
