Abstract (sommario):

Nowadays, coal mining is extending to deeper and deeper levels, facing ever increasing coal seam gas contents, much higher gas emissions and outburst risks. Capturing coal seam gas before it migrates into atmosphere has been seen as an effective approach to simultaneously improve mining safety, reduce greenhouse gas emissions, and produce clean energy. Thick seams account for a considerable share of global coal reserve. The application of longwall top coal caving (LTCC) method to extract thick seams generally yields a much higher productivity and is more efficient in comparison to a mechanised

Abstract (sommario):

Rock gas outbursts are a coal mine dynamic phenomena similar to rock bursts, however, they involve the active participation of large quantities of asphyxious and explosive gases under pressure. These events have occurred in the Sydney coal field, Cape Breton, Nova Scotia, where they have resulted in injury and economic hardship.<br>Because these phenomena are life threatening and not well understood and because geophysical methods have been identified as a means of studying these phenomena, an intrinsically safe microseismic monitoring system and method suitable for underground coal mines has

Abstract (sommario):

This thesis discusses an experimental study involving sorption studies using methane, carbon dioxide, and a multicomponent gas mixture representative of in situ gas composition. Using the isotherms for pure methane and carbon dioxide, isotherm and variation in gas composition with desorption for gas mixture were established using a numerical technique. When using gas mixture, composition of the desorbing gas at each pressure level was monitored. Results indicate that during desorption, methane concentration decreased as the pressure was decreased while carbon dioxide concentration increased. E

Abstract (sommario):

Gas diffusion in coals plays an important role in enhanced coalbed methane production, but a consistent picture of diffusion behaviour in coals is yet to emerge. There is no agreement on the most appropriate model, pressure dependence of diffusion coefficients, or the physical explanation to why CH4 diffusion is slower than CCh. The aim of the work towards this Thesis is to determine sorption kinetics more accurately, model them more systematically over a wider range of experimental conditions and resolve discrepancies present in the literature to explain (i) why uptake of ga

Abstract (sommario):

Coal Seam Gas (CSG) is a form of natural gas (mainly methane) sorbed in underground coal deposits. Mining this gas involves drilling a well directly into an underground coal seam, and pumping out the water (CSG water) flowing through it. Presently, CSG is under exploration in New Zealand (NZ); however, there is concern about CSG water disposal in NZ mainly because of the controversy that this activity has generated in some basins in the United States (US). The first part of this thesis studies CSG water from a well in Maramarua (NZ) and compares it to water from US basins. The NZ CSG water fro

This thesis describes a study of reactive transport processes in fractured rock in response to high pressure gas injection and displacement. This is achieved through the development and application of a theoretical and numerical modelling platform. A dual porosity, dual permeability framework has been formulated based on a mechanistic approach, which considers the coupled hydraulic, gas/chemical and deformation behaviour of fractured rock. The fracture network and porous rock matrix were treated as overlapping continua with distinct transport and storage properties. Flow in each continuum was

Abstract (sommario):

The permeability of coal is one of the most important basic parameters in the simulation of gas transport in coalbeds and in the evaluation of the commercial feasibility of coalbed gas reservoirs. However, the permeability of coal and its variation as gas is produced are still not well understood. Unlike that in conventional gas reservoirs, the gas permeability of a coalbed is influenced during gas production, not only by the simultaneous changes in effective stress and gas slippage, but also by the matrix shrinkage associated with gas desorption. The objective of this work was to investigate

Former manufactured gas plants (FMGPs) are a ubiquitous source of environmental con- tamination.

Coal tar contains a complex mixture of organic and inorganic compounds, many of which are toxic and carcinogenic. It is estimated that over 3000±1000 FMGPs exist in the United Kingdom alone, yet there are few recent publications detailing the analysis of coal tars. The complex composition of coal tar is known to vary due to a number of factors, including production method, temperature and coal t

Abstract (sommario):

Coal seam gas associated water (CSGAW) which is a main by-product of CSG production typically contains significant amounts of salts. The chemical composition of CSGAW is complex and may also contaminated with drilling chemicals contain heavy metals, carcinogens such as benzene, toluene, ethylbenzene and xylene, and radioactive elements like uranium. CSGAW has potential environmental issues; therefor it is unsuitable for further uses without proper treatment. The release of CSGAW to the land and rivers without proper treatment may drown vegetation, and endanger the aquatic life and environment.
