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 .树脂加长锚固高强锚杆支护能提高围岩力学参数 ,提供较高的支护阻力并具有较大的延伸率 ,适应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进巷道的稳定 ,并成功地应用于工程实践 . Through the analysis of stope stress in the fully mechanized top coal caving mining face and the strength strengthening theory of surrounding rock with bolt support, the control mechanism of surrounding rock along the roadway driving along fully mechanized caving face is proposed. Reinforcing bolting with high anchorage can improve the mechanics of surrounding rock Parameter to provide higher support resistance and greater elongation to meet the high-stress and large deformation of gob-side entry fully mechanized caving mining faces.The use of high-strength rock bolt support system can effectively maintain the fully mechanized top-coal caving roadway Stable, and successfully applied to engineering practice.
