Повышение эффективности работы щебеночных карьеров на основе оптимального обеспечения фронтов балластировочных работ

Abstract

Objective: To develop a theoretically justified methodology for transshipping process parameters determination as well as to improve ballast quarry operational efficiency on the basis of optimal provision of ballasting job operation fields. Methods: Operation of crushed quarries and ballasting facilities was studied through the methods of mathematical statistics as well as correlation analysis of technical and economic as well as organizational process parameters. Results: Areas of effective interaction of ballast quarries and ballasting facilities were determined. Operation lengths of shuttle-service trains running with engineering materials from loading terminal to detraining point were optimized. Effective load values of shuttle-service trains were estimated. The results are presented in table and graphic forms. Practical importance: Effective cost value area for ballast materials is recommended in contractors for practical application. Profitability of deliveries from crushed quarries was improved by providing ballasting job operation fields; guidelines on bedding of lines at railway stations and station blocks were developed as well as standards for October railway were introduced.
