Through on-site inspection for the typical coal mines of each coal tectonic units in Southwest Guizhou as well as analysis of gas parameter, highlight information and gas control technology, the thesis makes the following conclusions. Namely, the overall state of coal seam gas occurrence in Southwest Guizhou mining area presents characteristics with high degree in north and west together with low degree in east. With regard to the existing problems in gas control of this region, it has put forward some suggestions. For example, people shall add test parameters for coal seam gas in most mines, find out status of the mine gas occurrence, make specialized design in terms of gas emission characteristics and perform strict management to ensure proper implementation. Moreover, people can carry out targeted research for outburst prevention indicator, establish suitable predictor system, optimize instrument and equipment, match with current advanced production technology, introduce professional talents and strengthen training for related technology and management personnel.

The Relationship

This paper takes gas as a geological-mass to study, using gas geology theory, by analysising the geological conditions of Yongju mine in ShanXi, combining with the coal seam gas content data which measured underground to study the relationship between geological conditions and gas occurrence, reveal the gas occurrence factors: geological structure, roof and floor lithologic of coal seam, buried depth of coal seam and thickness of coal seam. Finally, using the measured data of gas content and gush, regression analysis, the gas gush is forecasted, playing a guiding role in the gas control and production safety .

This case study research examines informal adult learning in the Lock the Gate Alliance, a campaign against mining for coal seam gas in Central Gippsland, Australia. In the field of the campaign, circumstantial activists learn to think critically about the environment, they learn informally and incidentally, through socialization with experienced activists from and through nonformal workshops provided by the Environmental Nongovernment Organization Friends of the Earth. This article uses Bourdieu’s “theory of practice,” to explore the mobilization of activists within the Lock the Gate Alliance field and the practices which generate knowledge and facilitate adult learning. These practices have enabled a diverse movement to educate the public and citizenry about the serious threat fracking poses to the environment, to their land and water supply. The movements successful practices have won a landmark moratorium on fracking for coal seam gas in the State of Victoria.

AbstractCoal and gas outbursts are the result of several geological factors related to coal seam gas (coal seam gas pressureTo classify the outburst hazard level of a coal seam by means of statistical methods, this study considered the geological parameters of coal seam gas and statistical data on the amount of material involved in coal outbursts. Through multivariate regression analysis, a multivariate regression equation between the outburst coal quantity andUsing a significance evaluation of the aforementioned factors, the relative contributions of the gas-related geological parameters to the outburst hazard level of a coal seam were found to follow the orderThis work provides a scientific basis for evaluating the outburst hazard level of a coal seam and adopting feasible and economical outburst-prevention measures.
