Twenty-one papers from the proceedings have been entered individually into EDB; one had been entered previously from other sources. (LTN)

The faculty and staff are striving to overcome technical problems inhibiting the production of coal from the surrounding coal basin, such as the high-sulfur content of typical Illinois coals, subsidence of undermined lands, and the declining productivity of mechanized coal mining operations. Particular emphasis is given to solving coal production problems of the Illinois Coal Basin, which are somewhat different than those of the other US coal fields. Current faculty research emphasizes three areas: (1) rock mechanics and ground control; (2) coal processing; and (3) production engineering in surface and underground coal mines.

Specifically, we were to establish technology for fabricating cost-effective but marketable materials, like countertops and decorative tiles from the sludge. In addition, we were to explore the feasibility of forming siding material from the sludge. At the end of the project, we were to establish the potential of our products by generating 64 countertop pieces and 64 tiles of various colors. The tiles were to be mounted on commercial boards.

About 140 m. tons of coal is produced annually from the Illinois Coal Basin, which is located in ... more About 140 m. tons of coal is produced annually from the Illinois Coal Basin, which is located in Illinois, southwestern Indiana, and western Kentucky. A vast majority of recoverable reserves and production from the Illinois Coal Basin is, however, high-sulfur coal. Illinois, Indiana, Kentucky, and Missouri are among the top ten sulfur dioxide producer in the U.S. and will give to significantly reduce emissions over the next decade to meet the requirements of the CAAA~ This could be achieved through the use of FGD and FBC processes rather than switching over to low-sulfur western coal. The use of these clean coal technologies will significantly increase generation of coal combustion residues which must be disposed of or utilized. Over the next ten years, it is expected that Illinois coal users alone may produce about 15 m. tons of coal combustion residues annually. Therefore, there is an urgent need to determine cost efficient, environmentally safe methods of handling and disposal and utilization of these residues. The development of these methods will not only aid the coal industry in the midwest but throughout the U. s. This paper describes the research program "Disposal and Utilization of Coal combustion Residues from Illinois Basin Coal Users" (DUCCR) which was recently approved by the State of Illinois to deal with the issues related to disposal and utilization of coal combustion.

Using 23% F-fly ash and CFB fly ash in conventional concrete, 48 foundation piers for supporting a photo-voltaic array were constructed. The fly ash-cement concrete mix implemented has demonstrated strength properties that are comparable to that of conventional concrete. Synergy between F-fly ash and CFB fly ash is indicated for the achieved results that compare favorably to conventional concrete. Very low swelling has been measured for samples made from the implemented mix. The installation is performing up to expectations for the past 2.5 years. This successful demonstration holds a significant promise for other similar applications.

The developed combustion residuebased lightweight structural material will be used to replace wooden posts and crib members in underground mines. This report outlines the work completed in the first quarter of the project. The density gradient centrifbge @GC) has been used to separate a power plant fly ash sample into fractions of different density. Each of the fly ash hctions obtained by DGC, an aliquot of the unseparated fly ash and an aliquot of a magnetic component of the fly ash, were digested in strong acids following the procedures outlined in ASTM 3050. Preliminary experiments have also been carried out to study the effect of mix proportions and curing regimes on the strength and density on the developed material. The DGC separation test reveals that most of the fly ash sample (approx. 90%) has a density above 1.9 g/cm3. Indeed, nearly half ofthe sample has a density greater than 2.4 g/cm3. Since only a very small amount of this fly ash has a reasonably low specific gravity, it appears unlikely at this time that enough low density material would be isolated to significantly enhance lightweight concrete production using fiactionated material. A series of mixes have been made using fly ash, sodium silicate, cement, sand and water. Preliminary tests show that both cement and sodium silicate can be used as the binders to develop residues-based lightweight concrete. To date, compressive strength 1,290 psi have been achieved with a density of 133 pcf, with 50 g of cement, ash and 300 g of sand. Most of the work during the first quarter was done to the characteristics of the component materials. Tests are now being designed the required characteristics during the second quarter.
