Title: Coal Resource Previous HitDataNext Hit Processing, Old and New Techniques: ABSTRACT

Author(s): P. A. Burgess

Article Type: Meeting abstract

Abstract:

The use of Previous HitdataNext Hit-processing techniques in coal resource evaluation is characterized by a gradual adaptation of computer techniques rather than by any revolutionary breakthrough. The main thrust of the Previous HitdataNext Hit-processing effort is the use of computers to store and retrieve the large volumes of Previous HitdataNext Hit associated with core-hole analyses. The Previous HitdataNext Hit are of two types: (1) assay Previous HitdataNext Hit from coal seams; and (2) codified lithologic descriptions of the stratigraphic sequence of interest. The automatic contouring of assay isopleths is now a routinely accepted procedure; the limitations of the contouring algorithms have been offset by the ability to generate quickly large quantities of maps. The trend now is toward increasingly sophisticated use of available options such as trend analysis and the different geostatistical algorithms for interpretation, estimation, and classification.

In regard to stratigraphic Previous HitdataNext Hit, the main emphasis is a graphic Previous HitdisplayNext Hit of information to aid the geologist in interpreting the stratigraphic sequence. Some attempts have been made to automate the interpretation. In the near future, we expect to see the routine use of interactive graphic devices to aid the geologist in his work. The type of tool envisaged is analogous to the stratigraphic interpretation of Previous HitseismicTop records by petroleum explorationists.
