高瓦斯特厚煤层煤与卸压瓦斯共采原理及实践

Principles and Applications of Exploitation of Coal and Pressure Relief Gas in Thick and High-Gas Seams

论述了高瓦斯低透气性有煤与瓦斯突出危险特厚煤层和上覆采动断裂带有高瓦斯涌出的特厚煤层两种煤与瓦斯高产高效卸压共采模式、原理及其实践所取得的丰硕成果.阐明了现场考察得出的煤层采动引起远程上覆煤层卸压变形规律与卸压瓦斯抽采规律.

The high-gas and low-permeability thick seams were studied, where exist some danger of coal-gas outburst and high gas inflow. Two kinds of exploiting models of coal-gas and the principles were proposed, with which some program has been made in practice. In the course of site investigation, the discharging deformation rule of distant upper rock stratums caused by seam mining was obtained; at the same time, the rule of pressure relief gas rush was tested.
