| 摘 要： | 通过对综放工作面采场应力分析，运用锚杆支护围岩强度强化理论，提出了综放工作面沿空掘巷围岩控制机理，树脂和长锚固高强锚杆支护能提高围岩力学参数，提供较高的支搞阻力并具有较大的延伸率，适用综放工作面沿空巷道高应力和大变形特点，采用高强锚杆支护系统能有效地保持综放沿空掘巷道的稳定，并成功地应用于工程实践。

| Abstract: | The mechanism is put forward that is controlling surround rock of gateway driven along goaf in fully mechanized top coal caving face based on analysis of stress distribution around a coal face and theory of consolidating rock strength with bolt support. The stability of the surround rock is guaranteed by high strength bolt support bonded with resin grout. The high strength bolt is adaptive to high stress and large deformation of surrounding rock, because it can increase the strength of the surrounding rock, provide with high resistance support and big percentage elongation. Ended with an engineering instance, a new kind of successful supporting technique is introduced. |
