Definitions
- the present invention relates to special purpose vehicles and, more particularly, to underground mining vehicles adapted for working in potentially explosive atmospheres.
- Explosive or hazardous atmospheres are quite common in industrial processes and in particular in underground coal mines.
- the presence of an explosive mixture in the ambient air may not pose an immediate risk to personnel but machinery working in the area must be protected to prevent the accidental ignition of the explosive atmosphere. This technique is called explosion protection.

- Figure 12 is a table indicating weight savings due to various design and equipment choices used in a second preferred embodiment of the invention.
- the present invention is directed at a self propelled underground mining vehicle specifically for use in coalmines where potentially explosive gasses may be present.
- the vehicle of- the present invention is particularly suited for the transport of a small number, typically between one and three personnel, including the operator, and their equipment. This allows for the design of a smaller, lighter vehicle in which significant weight savings are achieved through the use of appropriate technologies to bring the vehicle's unladen mass to under 2000Kg.
- the vehicle To meet the requirements of underground mines, and particularly underground coalmines, the vehicle must be proof against the emission of sparks to allow it to operate in potentially explosive atmospheres.
- Four principle techniques are utilized in the vehicle of the present invention to meet this requirement , while significantly reducing it weight. These are, aspects of the engine/motor control system, flame traps, explosion proof enclosure of electrical equipment and/or intrinsically safe electrical components .
- a preferred embodiment of an underground mining vehicle 10 of the present invention is powered by a relatively small and light diesel engine 12. Power is transmitted in this instance to the rear wheels 14 by a transmission 16 integral with the rear transaxle 18.
- spark arrestor 20 is fitted between the air filter 22 and the intake manifold 24.
- Water flame trap .26 both prevents any sparks from reaching the external atmosphere and assists to cool the exhaust gasses.
- Detailed views of the water flame trap 26 and its installation according to the invention, are shown in Figures 2 and 3.
- known flame traps are designed to fit into the machinery of the vehicle, often formed as cube-like structures with flat surfaces and. sharp corners. This arrangement demands the use of relatively heavy construction materials- For example, a flame trap with an overhaul volume of 125 litres could weigh in excess of 120Kg (without water and fittings) . Also typically, the volume of these flame traps is relatively large so as to carry all of the water required for a reasonable duty cycle within the trap.
- the main body 30 of the flame trap 26 of the present invention comprises a cylinder 31 with hemispherical ends 32.
- This main body shape which is essentially that of a pressure vessel, allows it to withstand high internal pressures while minimizing the material tensile strength (and therefore the weight) required for the main body 30-.
- Figure 4 shows the relationship between pressure vessel diameter and vessel strength. It must be noted that a flame trap needs to be of a sufficient volume to . allow for sufficient water both in volume and depth to prevent .the
- this invention seeks to minimise the diameter of the vessel design and provide sufficient volume by a suitable length of the cylindrical shaped portion of the flame trap body, there is a limitation as to the minimum diameter of the flame trap.
- the smaller engine required to drive the smaller and lighter vehicle 10 of the present invention produces a significantly reduced volume of exhaust gas.
- the result is a lower volume of potentially explosive gas and a lower level of explosive energy which the flame trap is required to withstand, allowing the gross flame trap weight to be further significantly reduced.
- the flame trap main body 30 is partially filled with water and is connected to the exhaust of the diesel engine via a flameproof joint 34.
- the exhaust gases are then directed internally within the main body 30 to the bottom of the main body where they escape underwater, rising towards the top of the main body 30. From here they exit through the discharge outlet 28.
- the main body 30 may be opened via a flame proof joint 36 to allow the flame trap to be cleaned.
- the joint 36 may be bolted or screwed or similarly fastened but must be flame proof so as to prevent ignition of the atmosphere external to the flame trap. This joint may be located in different areas of the flame trap .if desired.
- the flame trap 26 is fitted with one or more water level sensors 37 which are designed to ensure that the engine can only operate while there is sufficient water in the flame trap.
- the flame trap 26 is further provided with a method of draining the water from the body via one or more valves 38. This allows the testing of the water, level sensor/s and float valves that may.be fitted to flame trap.
- a further reduction in the size and weight of the " flame trap of the present invention is achieved by the use of a top-up water header tank 40 (as shown in Figure 3) , connected by water conduit 41 to the inlet 42 of the trap 26.
- the water header tank 40 is located above the flame trap (as can be seen in Figure -1 ⁇ and is vented 43 so that it may provide top water to the flame trap. This provides that not all the water for a duty cycle of the vehicle need be accommodated in the flame trap body itself, but may be automatically topped up from a lightly constructed top-up water tank 40 through a one-way valve at fill point 42,
- the dry weight of the flame trap of the present invention is reduced from the typical figure quoted above of in excess of 120Kg, to 25Kg.
- the exhaust emissions are preferably further conditioned by an exhaust gas particulate filter (not shown) such as disclosed in US5,904,042 or US5,272,874.
- an exhaust gas particulate filter such as disclosed in US5,904,042 or US5,272,874.
- Such particulate filtering systems are designed primarily to improve the exhaust particulate levels and allow personnel to work safely in areas subjected to the vehicle's exhaust fumes.
- the weight reducing strategies of the present invention firstly include the provision of all lighting by high efficiency light emitting diodes (LEDs) . These diodes are five times more efficient than incandescent bulbs and can be arranged in groups or clusters as shown in Figure 6 to form a complete vehicle light 50.
- the reduced power required by the LED- lighting allows a reduction in the size of .the alternator- or generator 44 (shown in Figure 1) used to generate the electrical supply to the lighting circuits.
- the light emitting diodes 52 also produce less heat and are,, in the present invention, made explosion proof by encapsulating the light emitting diodes 52 in a clear casting resin 54.
- Figure 6 shows a vehicle light 50 comprising a cluster of LEDs 52 encapsulated in clear casting resin 54, Safety is in 'any case also enhanced by the fact that LEDs are non sparking given that they are solid state devices.
- control system for the LEDs is housed behind the cluster of diodes 52 in a
- main body 56 which is made of a robust plastic such as PVC or similar. Internally the main body 56 may also use encapsulation or increased safety techniques to explosion protect the electrical circuits in the vehicle, light 50 and the electrical supply cable 58 to the light. This0 combination of materials results in. a vehicle lighting system that is as little as one eighth the weight of flameproof lighting systems.
- compressed air has been used on mining vehicles for a variety of functions, including engine starting and emergency shut-down.
- the emergency shut-down function alone requires a large number of components as shown in Figure 7, amounting to a considerable weight impost of some 56Kg on the vehicle.
- the vehicle of the present embodiment of the invention incorporates intrinsically safe electrical sensors to monitor temperature, pressure and level of the engine. These sensors together with the shutdown valve used on the vehicle amount to 5Kg with, the whole occupying a volume of only 2 litres compared with the 200 litres of the traditional arrangement. This reduced volume amounts to a significant overall weight saving of approximately 20Kg as well as requiring less mounting space and associated equipment .
- the vehicle is equipped with either a spring or an hydraulic starting system for the diesel engine.
- a spring or an hydraulic starting system for the diesel engine This eliminates the air compressor and air tanks required for compressed air starting and emergency shutdown systems typically used on mining vehicles.
- a preferred spring starting system by Kineteco weighs approximately 4Kg whereas equivalent air starters and their valving weigh between 11 and 18Kg, thus a weight saving in the present vehicle of at least 7Kg.
- An hydraulic starting system has a similar weight as that of an air starter, but still avoids the use of the air components of Figure 7 and still provides a weight advantage.
- Yet another area in which the present invention has been able to make considerable weight reductions is in the use of body panels, fuel and water tanks formed of light-weight polymer composite material, instead of the typically used steel fabricated panels and tanks.
- Figure 10 shows some of the principle areas of weight savings for this embodiment of the invention.
- the unladen vehicle mass is again limited to no more than 2000Kg.
- the vehicle chassis, body panels and passenger and load configuration are similar or the same as that of the first preferred embodiment described above, but in this instance the vehicle is propelled by means of an electric power source coupled to at least one electric drive motor.
- the battery or battery pack 70 employed in this embodiment of the vehicle comprises high power density to weight ratio designs, such as Nickel Iron, Nickel Metal Hydride or Lithium Ion,
- the battery pack is housed in a battery compartment 71 made from, a high strength to weight ratio material resistant to battery acid, such as carbon fibre composites or stainless steel.
- the power supplied by the battery pack 70 is carried by cables to a main circuit breaker flame proof enclosure 72.
- Flame proof enclosures are heavy and in this preferred embodiment the number and size of the flame proof enclosures are minimised.
- the main circuit breaker enclosure 72 is in fact, the only flame proof enclosure used on the mining vehicle of this embodiment.
- the main circuit breaker enclosure 72 contains moving components capable of producing arcing and sparking, thus requiring that a flame proof enclosure be used to house these components..
- the electrical current passes from the main circuit breaker enclosure 72 to the main control enclosure 74.
- This main control enclosure 74 is not flame proof but is required to provide mechanical protection for the control components it contains and is thus manufactured from high strength to weight ratio material. These components are all solid state and are either encapsulated or emersed to provide explosion protection of the electrical circuits to the external atmosphere.
- the main control enclosure 74 supplies the electric motor or electric motors 76 and, depending on the operator inputs, will drive the motor forwards, reverse, slow or fast.
- the electric motor or motors 76 are in the preferred embodiment of the non sparking type having a high power to weight ratio. These motors are lighter than flame proof motors of the same output.
- operator control inputs 78 are intrinsically safe and therefore not capable o£ generating a spark that could ignite the external explosive atmosphere. These intrinsically safe circuits thus do not require any explosion proof enclosures , again helping to minimise the weight of the underground mining vehicle.
