LOG INTERPRETATION MODEL OF DETERMINING COALBED COAL QUALITY PARAMETERS

On the basis of the mothed of log equivalent volume model and the laboratory analysis information of coal samples, the authors develop the log interpretation model of determining coalbed coal quality parameters by the probable model method(multi variate liner regression method). The F test result shows that the equations which have been established are efficacious. The agreement between the coalbed coal quality parameters predicted by the interpretation model and those determined by the coal sample laboratory analysis can be seen clearly by the interpretation example. The conclusion is that the method which is concise and convenient to apply is effective, precise, and the study result is satisfactory.
