锚杆支护预紧力影响因素研究

The Study on Bolting Support Pre-tightening Force Infl uencing Factors

在理论方面论证了预紧力在锚杆支护系统中的重要性以及影响预紧力的因素,结合唐家会煤矿现场实际情况,研究了预紧力的影响因素并针对性地提出了提高预紧力的措施,为煤矿锚杆支护质量检查及支护设计施工提供了借鉴依据。

In theory demonstrating the importance of the pre-tightening force in the bolt support system as well as the inlfuence factors of pre-tightening force, and in combination with the practical situation of Tang JiaHui coalmine studying the inlfuence factors of pre-tightening force and puts forward the measures to improve the pre-tightening force, providing reference basis for bolt support quality check and support design and construction in the coalmine.
