Coal particle size and the degree of compaction significantly affect goaf heritage ventilated environment process spontaneous combustion coal, distribution are also affected by load application process, stress in is not uniform, resulting mined-out coal. It necessary to carry out experimental studies on coal crushing granularity under different loads loading processes clarify its law. Therefore...

The energy absorbing capability is one of the most important aspects of crushing behavior of a structure subjected to axial impact. In this paper, a simple practical method is introduced to enhance the crushing behavior of this kind of structure. The axial impact of metallic energy absorbing thin-walled tubes with special shaped cross-section is simulated using LS-DYNA software. The effect of c...

The present study deals with the utilization of fines generated from comminution process (crushing, grinding and screening) of the Run of Mines into value added products i.e. fluxed iron ore pellets. The study comprises to understand the physical and mechanical behavior of five distinguished chemical compositions of green and dried iron ore pellets with respect to a typical Mini Blast furnace (...

This paper develops a computational technique for finding the maximum allowable load of mobile manipulators for a given trajectory. The maximum allowable loads which can be achieved by a mobile manipulator during a given trajectory are limited by the number of factors; probably the dynamic properties of mobile base and mounted manipulator, their actuator limitations and additional constraints a...

in this paper, power system restoration in the presence of svc and tcsc in partial outage conditions is considered and a new method for maximum load restoration using different control variables is presented. control variables are tap of transformers, generation rescheduling and operating points of facts devices. objective function is restored load (to be maximized) and constraints are voltage ...

An apparatus is designed and fabricated for conducting experiments concerning fluidized segregation to verify a proposed design concept for a more efficient comminution machine. Previous studies have found that the fines distribute the intended crushing load imposed by the machine on the particle bed; thus, the load that must be applied to crush the larger particles increases. By removing the f...
