Coal waste materials inhibit direct vegetation establishment due to adverse physical and chemical properties, particularly low water retention and high potential acidity. The Moss No. 1 coal refuse pile is located in Dickenson County, Virginia, and was idled in the late `s with little topsoil resource available for final closure. Filtration primarily depends on a combination of complex physical and chemical mechanisms, not just sand. Media combinations are generally sand and anthracite coal. Multi-media or mixed-media filters generally use sand, anthracite coal, and garnet. In the high rate filter, the media size decreases and the top layers consists of a coarse File Size: 1MB.

Additional Physical Format: Online version: Stewart, Bill M. Physical property data on coarse anthracite waste. [Avondale, Md.]: U.S. Dept. of the Interior, Bureau. However, very little information has been developed on the properties and characteristics of anthracite waste.
During this Bureau of Mines research project, coarse anthracite breaker refuse from five sites in eastern Pennsylvania was sampled, and the physical properties, which indicate stability characteristics, were determined in the laboratory. Access to raw data. API Dataset FastSync.
Repository Physical property data on coarse anthracite waste / By Bill M. Stewart, L. (Lynn A.) Atkins and United States. Bureau of Mines. Abstract. Bibliography: p. Mode of access: Internet Topics: Anthracite coal. This research characterized and compared the physical and mineralogical properties of tailings of two ranks of coals: anthracite, a higher-rank coal, and bituminous coal, a lower-rank coal.
The physical properties of several common solid waste materials including poultry manure and compost were quantified under a variety of management practices and programs. Parameters relevant to the design and analysis of handling, transporting, and spreading equipment including moisture content, bulk density, angle of repose, maximum lump size.
In this study, various physical and mechanical properties of concretes were examined. These concretes were produced by the addition of C 16 (day compressive strength of 16 MPa) pieces as aggregate in weight percentages of (referred to total aggregate) 0, 30, 50, 70, and %.Cited by: Modern coal-quality data and geologic field observations are interpreted in terms of the coal geology in a small area near Pocahontas, Va.
Detailed chemical analyses and physical-property determinations of 12 channel-coal samples (reported on whole-coal and laboratory ash basis) indicate that the coals are mostly of high coking quality, lowCited by: 6. COAL RANK Anthracite coal is a dense, hard rock with a jet-black color & metallic luster.
It contains between 86% and 98% carbon by weight, & it burns slowly, with a pale blue flame & very little smoke Bituminous coal (in Indiana), contains between 69% & 86% carbon by weight Sub-bituminous coal contains less carbon, more. Chemical properties of MSW are very important in evaluating the alternative processing and recovery options.
Used primarily for combustion and waste to energy (WTE) calculations but can also be used to estimate biological and chemical behaviours. Waste consists of combustible (i.e. paper) and non-combustible materials (i.e. glass).File Size: KB. Information and data on the physical characteristics of solid wastes are important for the selection and operation of equipment and for the analysis and design of disposal facilities.
The major physical characteristics measured in waste are: (1) density (2) size distribution of components and (3) moisture content. The mechanical properties of most interest with respect to waste rock, mill tailings and coarse coal refuse are shear strength, moisture-density characteristics, and permeability.
A limited amount of data on these properties are available for waste rock, but the properties would be expected to be similar to those of conventional mineral aggregates of similar rock type and composition. Surface area of soil affects its physical and chemical properties and is largely determined by amount of clay present in soil: Specific surface area of soil particles Effective Area Specific Surface Area Particle Diameter (cm) Mass (g) (cm2) (cm2 g-1) Gravel 2 x x x Sand 5 x x x File Size: KB.
In this paper the physical and mechanical properties of coal-mine waste from different sites are described and the effects of these properties on the duty requirements of fill material are assessed. As a result of testing, it is concluded that if improving ground control is the only reason for backfilling, coal refuse alone does not appear to Cited by: Anthracite differs from ordinary bituminous coal by its greater hardness (–3 on the Mohs scale), its higher relative density of –, and luster, which is often semi-metallic with a mildly brown reflection.
It contains a high percentage of fixed carbon and a low percentage of volatile matter. Provide coarse aggregate for asphalt concrete base used in flexible pavements consisting of CCS, gravel, or crushed air-cooled slag.
Provide fine aggregate for asphalt concrete base consisting of natural sand or sand manufactured from stone, gravel, or air-cooled slag. Physical properties. With respect to high performance concrete produced with Coarse Mixed Aggregates in substitution of natural coarse aggregates: The coarse mixed aggregates had a higher absorption capacity and volume of voids, which significantly affected the final physical properties of the by: programmes.
For those Member States that have implemented waste inventory record keeping systems (the term WIRKS is coined in this publication to facilitate discussions of and references to these systems), their waste databases are used to record waste inventories according to national classification systems.
The present series of books has been produced based on the book “Biological wastewater treatment in warm climate regions”, written by the same authors and also published by IWA Publishing.
The main idea behind this series is the sub-division of the original book into smaller books, which could be more easily purchased and used.

Current practices of surface disposal consist of dual waste disposal systems, one for the coarse waste and one for the fine waste. Coarse waste is usually handled by truck, belt conveyor or aerial tram or a combination thereof, and de- posited directly on the waste pile. Although a vast number of studies investigated the improvement of the geotechnical properties of coal mine waste, the consolidation of fine-grained coal tailings slurry and its relationship with.3, and 4, which representing coarse, medium, fine and well gradation, respective-ly.
As can be derived from Table 2, three of the sands of each origin (1, 2 and 3) are poorly graded and the last sand group (4) is well graded. In order to ensure % coarse material inclusion, the soils in this study are washed under Sieve NoAn alternative fuel to replace foundry coke in cupolas was developed from waste anthracite fines.
Waste anthracite fines were briquetted with Si-containing materials and treated in carbothermal (combination of heat and carbon) conditions that simulated the cupola preheat zone to form silicon carbide nanowires (SCNWs).
SCNWs can provide hot crushing strengths, which are important in cupola Cited by:
