UNDERGROUND LOAD & HAUL
JCHX all lithium battery electric 2 m 3 underground LHD at Bauma China in Shanghai .
than four hours of continuous loading operations or 70 buckets of ore pass operations . In a 3.2 x 3.2 section , it can complete the ore and waste discharge tasks of 2 sections . A full charge time is 30-40 minutes , and when the workers are on a shift change , the machine can remotely complete more work . The operating cost is about 60 % of a diesel LHD of the same class .”
The working environment for the operator is improved significantly as local high temperatures caused by an engine no longer exist ; JCHX : “ to sum up this product achieved energy-conservation , environmental protection , low breakdown , improved safety and higher economic benefits at the same time .”
The new colour scheme of the LHDs refers to the JCHX flag / logo , while the product has been officially named as “ King Ant ” with the corresponding Chinese name having been registered at Administration for Industry & Commerce . The red , blue and white used on the body are the basic colours of the Jinchengxin ( JCHX ) flag . The red stripe shows J when viewed from the back , and C when viewed from the bottom up . The red and blue stripes cross and show X , which stands for JCHX , which is the English abbreviation of the company ’ s name . The King Ant name reflects the fact that it is an articulated machine , capable of lifting things far heavier than its own weight , implying a strong product carrying capacity .
JCHX adds : “ In recent years , as part of government policy and national reform , more attention has been driven to environmental
protection , sustainable mining development as well as green mining technology … redesign and upgrading of mining equipment based on new energy to be clean , zero-pollution , highlyefficient and automated is inevitably a necessity . Under such circumstances we believe our lithium-battery-driven LHD has distinct advantages in terms of safety , environmental friendliness , operational convenience , maintenance accessibility , as well as automation .”
The successful commissioning of the 2 m 3 battery electric LHD ( which was initially given the name JCY-2 during trials but is now also using the King Ant brand ) was achieved on July 8 , 2019 at the Lujiang pyrite mine near Hefei City in Anhui Province , which is owned by Anhui Jinniu Mining . At the time JCHX said : “ JCY-2 is a battery-driven , free of pollution and highly agile LHD , which is designed and developed for the purpose of minimising environmental pollution , reducing equipment operation cost and protecting employees ’ occupational health .”
JCHX says some of the transverse drifts at the Lujiang project are quite long with comparatively small sections , which leads to greater ventilation demands which was the main driver for the JCY-2 machine development . During 2.5 hours of operation at the 8-0 ore pass on the -296 metre level , the battery was reduced from 100 % down to 47 %; 14 draws ( approximately 34 m ³) weighing 120 t were loaded with the loading point located 160 m from the ore pass . The fan was not activated during the operation of JCY-2 , while the ambient temperature remained unchanged . According to the charging data , it
Getman ' s A64 underground primary fleet service platform
Getman says its service vehicles are designed to help perform key maintenance and repair functions throughout an underground mining operation , reducing the need for other production and production support vehicles to return to the workshop and helping maximise the time those vehicles spend in production and development roles . Part of Getman ’ s A64 product platform , its underground service vehicles protect operator safety through their purpose-built designs . Getman ’ s A64 Service Lube Vehicle offers three standard tank layout variations ranging from four to five tanks . They also may be customised for more or fewer tanks , based on specified requirements . All lube vehicles feature pressurised grease service , compressed air service , and include convenient delivery hoses with nozzles on heavy-duty spring return reels . The A64 Service Mechanic
Part of Getman ’ s A64 product platform , its underground service vehicles protect operator safety through their purpose-built designs
Vehicle offers a fully customisable mobile workstation and comes standard with toolboxes , compressed air service , a heavyduty crane , deck space , and storage compartments for transporting replacement parts and work lights . Available racks for oxy / acetylene tanks , grease services , and vice clamps are available upon request . Additional equipment may be mounted based on specific needs . The A64 Service Fuel Vehicle includes a single 2,000 gallon ( 7,571 L ) tank for refuelling operations underground and includes internal tank baffling for improved performance during tramming . The highrate delivery function includes a delivery line and nozzle mounted on a spring return reel for improved operation . Alternate tank sizes are available for enhanced manoeuverability . The company told IM : “ Getman A64 Service Vehicle ’ s purpose-built design keeps safety at the forefront . Features such as crane stabilisation eliminate the need for operators to physically handle heavy loads . All daily vehicle services and checkpoints are accessible from ground level and work areas are well-lit to ensure proper luminosity during servicing functions . Outward facing sight gauges are visible from ground level , and all mounted equipment is located on the perimeter of the rear deck , minimising the need for climbing on equipment .”
