煤巷锚杆支护对动压适应性的研究

Study on the suitability of bolting in coal gateways with the action of dynamic pressure

通过受动压作用煤巷锚杆支护的模型试验和数值分析研究发现：采动支承压力具有形成和发展过程，锚杆支护具有有效控制围岩和柔性支护的特点。

By means of simulation tests and numerical analysis, it is found that the abutment has the process of formation and development, bolting has the special features of flexible supporting and efficient controlling surrounding rock. Bolting is rather suitabl with the dynamic pressure.
