Actions to improve coal seam gas drainage performance
Coal seam gas drainage is affected by many factors which may be generally divided into two groups, geological factors and operational factors. Studies conducted in the Bulli seam found geological factors had a dominant impact on coal seam gas drainage while operational factors had a secondary impact, affecting the amount of optimum gas drainage performance achieved within the limitations impose...
متن کاملGas Permeability Evolution Mechanism and Comprehensive Gas Drainage Technology for Thin Coal Seam Mining
A thin coal seam mined as a protective coal seam above a gas outburst coal seam plays a central role in decreasing the degree of stress placed on a protected seam, thus increasing gas permeability levels and desorption capacities to dramatically eliminate gas outburst risk for the protected seam. However, when multiple layers of coal seams are present, stress-relieved gas from adjacent coal sea...
متن کاملHealth Effects of Coal Seam Gas - Tara
I visited Tara on 11 and 12 October as requested, to undertake a review of individuals who believe their health has been adversely affected as a result of coal seam gas exploration being undertaken in the region. Queensland Health provided the consultation room with the Tara health facility, and also advertised my attendance, and made appointments for those families and individuals who telephon...
متن کاملExtraction of Pressurized Gas in Low Air-Conductivity Coal Seam Using Drainage Roadway
A drainage roadway was constructed in the fractured zone beside an air-return roadway of a mining site. However, drainage roadways serve only one working face and are discarded after mining, thus weakening sustainable mining practices. To improve the sustainability at mining sites, this paper proposes a new drainage roadway that can serve two adjacent working faces. A schematic layout of the pr...
متن کاملEstimation of coal seams gas content for evaluating potential use of methane drainage system in Tabas coal mine
Methane gas emission, accumulation, and explosion are the most important risk factors in underground coal mines. Hence, having a knowledge of methane gas emission potential in underground coal mines is of crucial importance in preventing the explosion risk, loss of life, and property, and providing miners' safety. The purpose of this work is to provide the prediction maps for the C1, C2, and B2...
