Abstract
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.关键词
