Forces on Permeable Conductors in Magnetic Fields

Blasting injuries in surface mining with emphasis on flyrock and blast area security.

PROBLEM Blasting is a hazardous component of surface mining. Serious injuries and fatalities result from improper judgment or practice during rock blasting. This paper describes several fatal injury case studies, analyzes causative factors, and emphasizes preventive measures. METHOD This study examines publications by MSHA, USGS, and other authors. The primary source of information was MSHA's...

A numerical analysis of effect of segmental lining joints on tunnel support internal forces under seismic loading

During an earthquake, the better performance of segmental tunnel lining, compared to the continuous in-cast concrete lining, is generally related to the joints between segments. In order to better understand the influence of the segment joints, their effect on the internal forces induced in tunnel lining simultaneously with the effects of the other influential parameters should be considered. I...

Gas Forces on Disc Valves

This paper describes the measurement of the force exerted by the gas on a model disc valve as the gas escapes from the valve due to the disc being pulled from the stationary valve seat. The work forms part of a wider investigation of the aerodynamics of disc valves and reference is made to this. INTRODUCTION In previously reported work (1) it was found expedient to simulate the valve opening ph...
