numerical analysis - Opis:
- Numerical analysis of data from boreholes, applied during compilation of the "waste storage" database for the Geoenvironmental Map of Poland in 1 : 50,000 scale, allows quick and objective retrieval of comparable results. The goal of the borehole analysis is to find the proper insulating layers conforming to the waste storage standards, according to criteria specified in the Proclamation of the Ministry of the Minister of Environment dated on 24th March, 2003. The final result of such analysis is locating a natural geological barrier for depositories of neutral (O), hazardous (N) or other (K) wastes, with the most important insulative characteristics (depth of layer top, its thickness and lithology, presence of glacitectonic disturbances). The numerical analysis of data consists of 8 stages. Stage I assigns lithology of particular stratum to relevant insulation category (O, K, N). Stages II-III involve combining of the adjacent strata into stacks with the same or different insulation category and calculating their thickness. After excluding stacks thinner than 1 m (stage IV), checking the thickness of layers conforming to the hazardous waste storage standards (V) and taking into account the glacitectonic disturbances within the analyzed layers (stage VI), a natural geological barrier is delineated (stages VII-VIII). The practical advantage of the analysis is that the method is fast and gives unbiased, repeatable results.
