[0119] overview

[0120] now refer to figure 1 and figure 2 An overview of the mining machine 3 is described. The mining machine 3 includes a ranging system 100 to determine relative position data of the mining machine 3 to an object 7 with the object's position. The object 7 may be any object, such as a wall 12 of a mine detectable by the ranging system 100 .

[0121] now refer to figure 2The ranging system 100 of the mining machine 3 is briefly described. The ranging system 100 includes an electromagnetic output device 102 to provide a first beam 104 of electromagnetic radiation along a first beam path 106 to the object 7 . The first beam 104 is reflected from the object 7 to provide reflected electromagnetic radiation 110 . The ranging system 100 also includes an electromagnetic input device 108 to receive the first beam of reflected electromagnetic radiation 110 from the object 7 to determine a distance 114 from the ranging system 100 to the object 7 . The distanc...

Abstract

The invention relates to a mining machine including a range finding system and a method for monitoring the position of the mining machine. The range finding system comprises an electromagnetic output (102) to provide a first beam (104) of electromagnetic radiation along a first beam path (106); an electromagnetic input (108) to receive reflected electromagnetic radiation (110) of the first beam from an object (7) for determining a range (114) of the range finding system (100) from the object (7); and an enclosure (120) including a side wall (122) that surrounds a central axis (136) of the enclosure (120), the side wall (122) transparent to the electromagnetic radiation provided by the electromagnetic output (102). The electromagnetic output (102) and electromagnetic input (108) are disposed within the enclosure (120) such that the electromagnetic input (108) is located outside a second beam path (124) of a second beam (126) of electromagnetic radiation defined by a specular reflection (128) of the first beam (104) on the side wall (122). The mining machine (3) also has a data port (40) to output relative position data of the mining machine (3) to the object based on at least the determined range (114).

Description

technical field [0001] The present disclosure relates to mining machines with ranging systems. Background technique [0002] It may be necessary for the excavator to move to different locations in the mine as required. Some mining machines are vehicles that are navigated through workings in a mining area. The environment in a mining site can challenge known methods of determining vehicle location. [0003] Mining areas can include dusty conditions where traditional lane markings for roads can become obscured by dust and other debris. Further, mines may operate underground or in other low-visibility conditions that may affect visual observation. Furthermore, due to the obstruction of the soil or multiple signal paths, it will be difficult to use navigation based on satellite transmission signals (or local transmission signals). [0004] Other navigation methods may be used, such as dead reckoning for position based on accelerometer and gyroscope results. Further, speedom...
