锚杆支护的主动、及时支护,主要体现在锚杆支护体系对巷道围岩施加较大的、及时的初期支护阻力,初期支护阻力提高了围岩的自承能力、有效控制了巷道围岩变形。锚杆支护体系的初期支护阻力是由锚杆的初锚力产生的,初锚力则是由安装锚杆时施加在锚杆上的预紧力产生的。锚杆预紧力是体现锚杆支护的主动性、及时性的主要指标。合理的预紧力可提高岩层的自支撑能力,保证整个锚杆支护体系充公发挥支护效能。

Bolting the active, timely support, mainly in bolting system imposed on the larger surrounding rock, the early and timely support resistance, the resistance of this initial support, improved self - rock beating capacity, effectively control the deformation of surrounding rocks. Early bolting system of support resistance is the initial anchor bolt generated, the initial anchor bolt is applied by the bolt when installed on the bolt preload generated. Bolt preload is reflected bolting initiative, the main indicators of timeliness. Reasonable pretension can increase the capacity of self - supporting strata to ensure that forfeiture of the entire play bolting support system performance.
