The Role of In-Situ Stress in Coalbed Methane Explorationte has on coal seam permeability, and hence gas/water producability. Similar understanding is also emerging from other parts of the world. The aim of this contribution is to elaborate the context in which stress appears to influence coal seam permeability in Australia, and to investigate some of the

Mechanical and Thermal Control of Cleating and Shearing in Coal: Examples from the Alabama Coalbed Msociated mechanisms of formation is essential for effective coalbed methane exploration and field management. Natural fractures in coal can be divided into two general types: cleat and shear structures. Cleat has been studied for more than a century, yet the mechanisms of cleat formation remain poor

10 and France in 1845. In eastern Australia methane-related mine disasters occurred late in the 19th century with hundreds of lives lost in New South Wales, and as recently as 1995 in Queensland‘s Bowen Basin. Ventilation and gas drainage technologies are now in practice. However, coalbed methane re

The Relation between Gas in Coal Seams and Artificial Coalification Gas Under Hydrothermal Pressureorigin of coal and its chemical properties at atmospheric conditions by artificial coalification experiments. T. Yamazaki and R. Abe reported the experimental results of the gas evolutions from raw coal during the artificial coalification process following the procedure presented by C. Yakakawa.
