沙曲矿煤层单巷掘进工作面防突方案研究
he Anti-outburst Scheme of Single Roadway Driving
本文在煤巷掘进工作面煤和瓦斯突出机理的出发，着重分析突出煤层掘进工作面周围煤层及围岩的应力变化规律，同时对定掘进工作面周围应力区域进行划分，研究煤巷掘进工作面的防突措施作用机理，在此基础上借助有限元方法利用ANSYS软件建模分析了掘进工作面周边围岩的应力集中影响区域，从而提出掘进工作面防突技术方案。
his article from the start of coal and gas outburst occurring mechanism,focuse on analysis of ground stress variety in surrounding rock and coal seams around heading face especially in the first driving, meanwhile stress areas surrounding heading face is compartmentalized, on the basis of which ANSYS software establishs 3D model by finite element method to analyze the range that stress concentration influenced around heading face and recommend the technological scheme of outburst prevention in heading face.
