Problems solved by technology

[0007] However, in a mining environment, the operation of the fan arrangement produces a large amount of noise which is both unpleasant and dangerous to mining personnel as the noise itself may be damaging to hearing and may also mask what would otherwise be possible Heard of other potential hazards occurring

Embodiment Construction

[0029] The filter device of the present invention mounted on a bolter miner, which is an electric, track-mounted continuous mining machine designed to simultaneously excavate roads and install roof bolts, will now be described by way of example with reference to a preferred embodiment. This mining machine includes a set of cutter drums mounted on a hydraulically actuated frame to enable independent movement of the drums relative to the main frame and tracks. Accordingly, the filter device according to the invention is also mounted movably on the machine. The machine also includes a roof and rib bolter mounted on a stationary part of the main frame that is operable throughout the cutting cycle.

[0030] refer to figure 1 , the mining machine 100 includes a main frame 101 that provides support for an underframe or chassis (not shown) that supports a pair of endless driven tracks (not shown) for driving on the ground and along The machine 100 is propelled against the coal seam or...

Abstract

A dust filtering unit mountable at a mining machine (100). The filtering unit comprises a filtration duct (113) having a scrubber unit and demister where airflow through the filter unit is driven by an exhaust fan (114). Noise emission from the fan is reduced by a first flexible coupling (502) positioned between the fan unit and a filter duct and a second flexible coupling (703) mounting the fan unit at a filter support frame (109).

Description

technical field [0001] The present invention relates to a dust filter device mountable at a mining machine, and in particular but not exclusively to a mining machine having a dust filter device configured to minimize the operation of the filter device and / or the mining machine Transmission of vibratory forces between components. Background technique [0002] Various methods and machines have been developed to extract minerals and other valuable materials at and below the Earth's surface. Such machines are often operated at great depths in mines. [0003] In order to maximize excavation and mineral recovery efficiency, mining machines have been developed for specific purposes. While certain machines are configured exclusively to cut minerals from sediment or coal seams, others are configured to tunnel at depths underground to efficiently create mine shafts and provide access for mineral cutters. In particular, mobile mining machines have emerged as successful devices for p...
