Blog Article

To evaluate the safety performance of bolt support scientifically, the factors affecting bolt support are systematically analyzed, the comprehensive evaluation index system is established from four aspects: support parameters, Market dynamics and future prospects of the automobile industry in Saudi Arabia quality of bolt and fittings, construction management and monitoring level, and the safety evaluation model of bolt support is constructed; the AHP and entropy weight method are combined to determine the weight of each index, and the safety evaluation system of bolt support based on AHPentropy Return to Sports and Sports Activities after Treatment of Osteochondral Lesions of the Ankle in Elite Athletes weight method is established and its application program is developed.The safety evaluation method and application program proposed in this paper are applied to the safety evaluation of bolt support in a coal mine in Shanxi Province, and the results are in agreement with the actual situation.This article studies the correlation.
