综放工作面的瓦斯涌出特征分析

摘要

高瓦斯工作面采用综放开采时，其瓦斯涌出及分布规律相比于普通分层开采工作面存在特殊性。论述了综放工作面瓦斯的涌出规律、分布特征以及运移规律等，分析了高瓦斯综放工作面的瓦斯来源、分布、运行规律，瓦斯上浮效应、瓦斯集聚点及开采过程中瓦斯涌出规律等主要特征，为综放开采制定瓦斯防治措施等方面提供了理论依据。%Mechanized caving mining was used in High Gas Faces,the distribution rule and gas emission com-pared to ordinary layer mining working face has the particularity,distribution characteristic and migration law in mech-anized caving face,analyses gas source,distribution,the main features of operating law,gas floating effects,gas gath-ering points and gas emission law during the process of high gas mechanized caving face mining,The conclusion pro-vides a theoretical basis for controlling measures of the caving mining gas and other aspects.
