NIOSH is developing bit and chuck isolators to reduce vibration, and thus noise radiation of the drill steel, with the longer term goal of reducing roof bolting machine operator noise exposure. Laboratory testing has shown that operator ear sound pressure levels may be reduced by 3 to 7 dB, depending upon the test configuration and drilling ...
A Russian company, focused on developing highly bespoke mining machinery for coal and pot ash mines, required highly robust hydraulic cylinders to be placed inside the state of the art machines. They were producing a run of three different machines, with each machine weighing up to 300 tons.
The research continued through development of intelligent proximity detection for continuous mining machines and is now focused on developing proximity detection system design guidelines for mobile equipment. All of this research has been published in detail as the work has progressed but there exists no summary or overview document.
Abstract The paper presents the process of a seat model development for mining machine operators. The lack of availability of such numerical models was the motivation for the authors as the cabin seat with the integrated seat belt is a fundamental safety equipment.
The photo below is a makeshift, home made mining machine. The graphics cards are those rectangular blocks with whirring fans. Note the sandwich twist ties holding the graphics cards to the metal pole.
The framework provides a guide for designers and manufactures of sheet metal machines in developing the new machine. To develop the framework, research used various tools such as reviewing ...
