　　基于深部煤巷生产地质条件，采用数值模拟方法研究了锚杆受力与其位置、安装角度的关系，揭示了深部煤巷锚杆受力分布规律。肩角锚杆轴力较大；构造应力越大，肩角锚杆轴力越大，肩角锚杆最易发生破断失效；安装角度对肩角锚杆轴力影响较大，安装角度越大，其最大轴力越大。基于肩部锚杆受力分布特征，提出了肩角围岩控制技术：掘巷初期，肩角锚杆安装角度应尽可能小，避免杆体穿过煤层与顶板交界面；煤层沿顶板发生滑移后，补打倾角较大的肩角锚杆，将煤层与顶板锚固在一起，加强控制肩角围岩。

Based on the geological condition of a deep coal roadway,study was carried out on the relation between the rock bolt stress with its position and fixing angle by using the numerical simulation method,and the distribution law of rock bolt stress in the deep coal roadway was revealed. The shoulder bolt was featured by its larger axial force;the greater the tectonic stress,the greater the axial force of the shoulder bolt, as a result, the shoulder bolt was broken most easily. The fixing angle has great influence on the axial force of the shoulder bolt,the greater the fixing angle,the greater the maximum axial force. Based on the stress distribution characteristic of the shoulder bolt,the control technique for surrounding rock in shoulder area was proposed. At the beginning of the roadway excavation,the fixing angle of the shoulder bolt should be as small as possible in order to avoid the bolt body to pass through the bedding face between coal seam and roof;after the slippage of coal seam along roof,it is necessary to fix the shoulder bolts with a bigger dip angle so as to fasten the coal seam and roof together and strengthen the control of the shoulder surrounding rock.
