摘要
在采动应力影响下,含瓦斯煤岩渗流特性的变化会对瓦斯的抽采产生较大影响。从现场实测数据入手,主要侧重于研究在采动应力影响下对瓦斯抽采效果的影响和影响范围确定的途径和方法,为钻孔设计和提高瓦斯抽采系统抽采效率提出了建议。
Influence by mining induced stress, the change of seepage characteristics of coal and rock containing gas will have great influ- ence of gas extraction, from the perspective of the field measured data, this paper mainly focused on the research on dynamic stress un- der the influence of the impact on the effect of the gas extraction,and method of determining the influencing scope of gas drainage. Be- sides,some suggests were also proposed for the design of boreholes and the improving of the gas drainage effects.
