The Uses of Peat for Fuel and Other Purposes

Description: From Introduction: "The bulletin sets forth the results of an investigation that was undertaken to determine whether peat, a fuel widely used in some countries, could be made serviceable in the United States, where, through labor and economic conditions differ from those in peat-using countries, there are opportunities for the introduction of a fuel selling at prices that should make the mining and shipment of peat to near-by markets profitable."

Disposal of coal preparation wastes: environmental considerations. [17 refs]

Description: The mineral wastes from coal preparation and mine development constitute a major environmental problem. Over 3-billion tons of these materials have accumulated in the U.S., and the current annual rate of waste production of 100 million tons/yr is expected to double within a decade. The total number of active and abandoned coal waste dumps is estimated to be between 3000 and 5000. About one-half of these pose some type of health, environmental, or safety problem. Structural weaknesses in coal re… more

Laboratory Velocity Measurements Used for Recovering Soil Distributions from Field Seismic Data

Description: Recent advances in field methods make it possible to obtain high quality compressional (P) and shear (S) velocity data for the shallow subsurface. Environmental and engineering problems require new methods for interpreting the velocity data in terms of sub-surface soil distribution. Recent advances in laboratory measurement techniques have provided high quality velocity data for soils at low pressures that can be used to improve interpretation of field data. We show how laboratory data can be u… more

Comparing geophysical measurements to theoretical estimates for soil mixtures at low pressures

Description: The authors obtained good estimates of measured velocities of sand-peat samples at low pressures by using a theoretical method, the self-consistent theory of Berryman (1980), using sand and porous peat to represent the microstructure of the mixture. They were unable to obtain useful estimates with several other theoretical approaches, because the properties of the quartz, air and peat components of the samples vary over several orders of magnitude. Methods that are useful for consolidated rock … more

Evaluation of European empirical methods for subsidence in US coal fields

Description: The purpose of this study was to assess the applicability of European subsidence methods for the emerging US longwall practice. Subsidence prediction in Europe has typically used either graphical methods (United Kingdom) or mathematical methods. The mathematical methods utilize either profile or influence functions. The graphical methods were developed in the United Kingdom (UK) by the National Coal Board (NCB) from subsidence data obtained from numerous mines. Although a large data base in the… more

Phase equilibria for complex fluid mixtures

Description: After defining complex mixtures, attention is given to the canonical procedure used for the thermodynamics of fluid mixtures: first, we establish a suitable, idealized reference system and then we establish a perturbation (or excess function) which corrects the idealized system for real behavior. For complex mixtures containing identified components (e.g. alcohols, ketones, water) discussion is directed at possible techniques for extending to complex mixtures our conventional experience with re… more

European empirical methods applied to subsidence in U. S. coal fields

Description: The empirical methods commonly used in Europe to describe the shape of subsidence troughs are tested against the field data of the York Canyon Mine in Northern New Mexico. This mine is in a flat lying seam under rugged terrain. The subsidence data consists of time-correlated measurements of surface displacements above two longwall panels. While the profile fits from the graphical methods (United Kingdom) do not agree with the measured profiles, the profile functions of the error integral type u… more

Inorganic contents of peats

Description: Peat, the precursor of coal, is composed primarily of plant components and secondarily of inorganic matter derived from a variety of sources. The elemental, mineralogic, and petrographic composition of a peat is controlled by a combination of both its botanical and depositional environment. Inorganic contents of peats can vary greatly between geographically separated peat bogs as well as vertially and horizontally within an individual bog. Predicting the form and distribution of inorganic matte… more

Package Equivalent Reactor Networks as Reduced Order Models for Use with CAPE-OPEN Compliant Simulation

Description: Engineering simulations of coal gasifiers are typically performed using computational fluid dynamics (CFD) software, where a 3-D representation of the gasifier equipment is used to model the fluid flow in the gasifier and source terms from the coal gasification process are captured using discrete-phase model source terms. Simulations using this approach can be very time consuming, making it difficult to imbed such models into overall system simulations for plant design and optimization. For suc… more
