Reliability, availability and maintainability (RAM) analysis of a dragline

11 Mar 2020 / by DEEPAK KUMAR, SUPRAKSH GUPTA and PAWAN KUMAR YADAV

Dragline is one of the crucial heavy earth moving machines (HEMM) which is used in opencast mine. It has significant role in opencast mine to improve the overall production and remove the overburden; performance of dragline depends on the reliability, availability and maintainability (RAM) of the subsystems.

Study and analysis of a full-scale laboratory successive alkalinity producing system for ironremoval during the treatment of acid mine drainage

11 Mar 2020 / by M. D. PATEL, R. K. JADE and P. K. DEWANGAN

The Successive Alkalinity Producing System (SAPS) is widely accepted for the treatment of acid mine drainage (AMD). The effectiveness of SAPS depends upon many parameters such as hydraulic retention time (HRT), influent quality, characteristics of organic substrate and their design aspects etc. In this laboratory SAPS column study, four synthetic AMD solutions were treated for …

Finite element based modelling and analysis of dragline boom structure

11 Mar 2020 / by ASIT SHUKLA and PIYUSH RAI

Dragline is the most widely used machine in opencast mining. It is used for removal of overburden in coal mining. During the digging process machine experiences various loadings on its front end structure, which typically consist of boom, bucket and wire ropes. These loads tend to develop stresses in each cycle of the dragline and …

Solid waste management in urban mines based on resource reutilization mode of cleaner production

11 Mar 2020 / by D.Q. DENG F. F. JIANG Y. DUAN and L. PENG

Tailing-cement filling is used in Laixin iron mine for improved protection of the Earth’s surface, prevention of surface collapse, and sustainable development. The tailing is composed of over 40% particles with a diameter of –20 µm and is thus classified as extremely fine tailing. A proportioning test proves that the tailing is difficult to combine …
