Abstract
Abstract An auger for use in a continuous mining operation having an elongate tubular member in communication with a fluid pressure source and a scroll mounted on the tubular member with spray mechanisms for spraying fluid into the air adjacent the peripheral edge of the scroll for preventing suspension of mined undesired contaminate particulate matter within the air adjacent to the continuous mining operation.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
227 words
An auger for use in a continuous mining operation for preventing suspension of mined undesired contaminate particulate matter within the air adjacent to the continuous mining operation, comprising: an elongate tubular member having a longitudinal bore formed therein and having a first end and a second end, said longitudinal bore of said tubular member adapted to be in communication with fluid pressure means adjacent said second end, said tubular member adapted to be rotated adjacent said second end; a scroll having an inner peripheral edge and an outer peripheral edge for use in mining materials from the mine, said scroll radially spiralling along the longitudinal axis of said tubular member from said first end to said second end with said inner peripheral edge being mounted with said tubular member such that rotation of said tubular member results in rotation of said scroll for mining materials from the mine while generating undesired contaminate particulate matter; spray means terminating adjacent said outer peripheral edge of said scroll and in fluid communication with said fluid pressure means for spraying fluid into the air adjacent said outer peripheral edge of said scroll preventing suspension of mined undesired contaminate particulate matter within the air adjacent to the continuous mining operation; and, anti-clogging means being affixed with said spray means for continuously preventing clogging of said spray means during spraying of the fluid.
Claim 2
Dependent Claim
227 words
An auger for use in a continuous mining operation for preventing suspension of mined undesired contaminate particulate matter within the air adjacent to the continuous mining operation, comprising: an elongate tubular member having a longitudinal bore formed therein and having a first end and a second end, said longitudinal bore of said tubular member adapted to be in communication with fluid pressure means adjacent said second end, said tubular member adapted to be rotated adjacent said second end; a scroll having an inner peripheral edge and an outer peripheral edge for use in mining materials from the mine, said scroll radially spiralling along the longitudinal axis of said tubular member from said first end to said second end with said inner peripheral edge being mounted with said tubular member such that rotation of said tubular member results in rotation of said scroll for mining materials from the mine while generating undesired contaminate particulate matter; spray means terminating adjacent said outer peripheral edge of said scroll and in fluid communication with said fluid pressure means for spraying fluid into the air adjacent said outer peripheral edge of said scroll preventing suspension of mined undesired contaminate particulate matter within the air adjacent to the continuous mining operation; and, anti-clogging means being affixed with said spray means for continuously preventing clogging of said spray means during spraying of the fluid.
Claim 3
Dependent Claim
30 words
The auger of claim 1, wherein: said spray means directs fluid from said fluid pressure means in a radial direction substantially perpendicular to the longitudinal axis of said tubular member.
Claim 4
Dependent Claim
36 words
The auger of claim 1, further including: bit means mounted adjacent said outer peripheral edge of said scroll for mounting appropriate cutting tools for cutting into and loosening the mined materials for removal from the mine.
Claim 5
Dependent Claim
54 words
The auger of claim 3, wherein: said spray means terminating adjacent to said bit means on said outer peripheral edge of said scroll to enhance the direction of fluid from said spray means at said bit means for preventing suspension of undesired contaminate particulate matter within the air in proximity to said bit means.
Claim 6
Dependent Claim
43 words
The auger of claim 1, wherein said spray means further includes: at least one body member adapted to be mounted with said scroll, said body member having an orifice formed therein, said body member being in fluid communication with said fluid pressure means.
Claim 7
Dependent Claim
51 words
The auger of claim 5, wherein said anticlogging means includes: insert means movably mounted in said orifice of said body member for agitation by the fluid flowing through said orifice to prevent clogging of said orifice with mined particulate matter during continuous mining operations and to enhance dispersion of the fluid.
Claim 8
Dependent Claim
40 words
The auger of claim 6, wherein said insert means includes: a cotter pin disposed within said orifice and adapted to be agitated by the fluid flowing through said orifice preventing clogging of said orifice and enhancing dispersion of the fluid.
Claim 9
Dependent Claim
55 words
The auger of claim 1, wherein: said scroll has a face for conveying mined materials along the longitudinal axis of the tubular member by rotation of said tubular member and said scroll therewith and a back portion in opposed relation to said face, said spray means being mounted on said back portion of said scroll.
Claim 10
Dependent Claim
40 words
The auger of claim 9, further including: channel means mounted on said back portion of said scroll for providing the fluid interconnection therebetween said longitudinal bore of said tubular member having said fluid pressure means therewith and said spray means.
Claim 11
Dependent Claim
25 words
The auger of claim 9, wherein: said channel means is mounted on said scroll substantially radially perpendicular to the longitudinal axis of said tubular member.
Claim 12
Dependent Claim
247 words
A continuous mining operation, comprising: a continuous miner for excavating and conveying mined materials from within a mine, said miner being movable to a variety of mining locations; an elongate tubular member having a longitudinal bore formed therein and having a first end and a second end, said tubular member adapted to be mounted with said continuous miner adjacent said second end, said longitudinal bore of said tubular member adapted to be in communication with fluid pressure means adjacent said second end, and said tubular member adapted to be rotated by said continuous miner adjacent said second end; a scroll having an inner peripheral edge and an outer peripheral edge for use in mining materials from the mine, said scroll radially spiralling along the longitudinal axis of said tubular member from said first end to said second end with said inner peripheral edge being mounted with said tubular member such that rotation of said tubular member results in rotation of said scroll for mining materials from the mine while generating undesired contaminate particulate matter; spray means terminating adjacent said outer peripheral edge of said scroll and in fluid communication with said fluid pressure means for spraying fluid into the air adjacent said outer peripheral edge of said scroll preventing suspension of mined undesired contaminate particulate matter within the air adjacent to the continuous mining operation; and, anti-clogging means being affixed with said spray means for continuously preventing clogging of said spray means during spraying of the fluid.
