低透气性复合煤层群开采矿区的瓦斯综合治理与开发

本文介绍了高瓦斯、低透气性、复合煤层群开采矿区的瓦斯综合治理与开发，指出只要从安全、资源、环保的角度出发，在现场管理中给予高度重视，通过采用先进的地面原始煤层压裂井技术、地面垂直采空区钻井技术、灵活多变的井下抽采技术等多种方式，煤矿掘进工作面、采煤工作面的瓦斯是可以控制的，同时煤矿瓦斯也是可以得到有效的综合开发利用的。

Comorehensive Control and Development of Gas in Compound Multi-Coal Seams with Low Permeability in Coal Mining Area

This paper describes comprehensive control and development of gas in a group of high gas and low permeability coal seams. It points out that from the view point of safety, resources and environment protection, if only great attention is paid to the site management, and if the advanced surface hydraulic fracturing of virgin coal seams boreholes, the surface vertical gob wells and flexible underground gas drainage technologies are applied, and the gas hazards in heading faces and work faces can be controlled properly. At the same time, CMM can be effectively developed and utihzed.
