INTRODUCTION

Truck haulage now a days is the most widely recognized methods which is utilized for moving metal/squander in open-cast mining tasks. The truck haulage is normally the costliest unit activity in a truck shovel open cast mining. The progression in computer coding innovation has progressed to a point wherever are several truck dispatching frameworks that would provide the capability of propelling truck-shovel efficiency and future reserve funds. Attempting a dispatching framework in a mine can give operational gains by minimizing waiting times and acquire other useful points of interest through great monitoring, ideal steering. Limit of the utilized truck-shovel armada relies upon the dispatching technique being used, the complexity of the truck shovel framework and various different factors. It is an extremely basic circumstance in mining that significant number of examination of the accessible systems is embraced before dispatching is taken. In many number of cases, computer reenactment is the better pertinent and viable strategy for relating the option dispatching procedures. In shovel dumper mix framework the primary destinations are To expand the profitability and to diminish the time of activity. These are finished by: • Minimizing shovel wait time (MSWT): The vacant truck in this goal is doled out to the shovel which will wait for a truck the longest time, or is relied upon to be inactive next. • Minimizing truck cycle time (MTCT): The essential point of this methodology is to allocate an accessible void truck to the shovel which will give the base an incentive to consummation of the normal truck cycle time to amplify the absolute tons or ton-miles per unit of time. • Minimizing truck waiting time (MTWT): The essential point of this methodology is to allocate an unfilled truck to the shovel where the truck stacking activity will be started first. • Minimizing shovel saturation (MSS): The essential point of this procedure rule is to dole out the trucks to the shovel at equivalent time interims to keep a shovel working without waiting for trucks. The truck is dispensed to the shovel which has the most minimal proportion of the present inclusion against wanted inclusion. industry with a portion of over 80% and 54% separately of complete generation in Coal India Limited and SCCL, calls for inside and out investigation of the various ways and strategies for expanding the creation and Performance of surface mining frameworks in the up and coming years. Regardless of whether there will be any surface Mining frameworks of disparate sizes and improvement, there is no wary that surface mining frameworks from little scale to medium scale and uber estimated mines, would call for unmistakable contributions of new innovation to be viable exorbitant, eco-accommodating and meet the creation needs. In taking a stab at new degrees of working in the aggressive condition, innovation will be the corpus level for change, where computer innovation will assume a focal job. Benchmarking of surface mining tasks overall unveil a yawning hole between the exhibition capability of the better of the mines and the most manufactured of the mines and there exists a jussive mind-set need to traverse this hole. Since, the size of activities in opencast coal mines in India has developed significantly; the traditional strategies like surveying, arranging and working the mines ought to be moved up to arrive at the requests. A total host of driving technology products and systems for good, efficient management of surface mines have evolved in the past decade [1].

Computers used on board mining equipment must contend with difficult environmental conditions. When the machines are unattended in the field the temperatures can range from the very cold to the very hot. When the machine is in operation, it is subjected to vibration and sometimes to relatively high dust levels. To be useful to the operator it must be easy to use and be visible under varying ambient is necessary to hold the operating system, system software and complex designs. The computer ought to have a touch screen for simple activity. It must be sufficiently quick to process pail positions and update screen foundations in a creation circumstance.

Radio telemetry systems are expected to transmit GPS amendment signals, to download structures to the machines and to transfer as assembled DTMs when the activity is finished. Numerous GPS study units use VHF signals for GPS rectifications. These radios are useful for inclusion however have insufficient data transmission to transmit complex structures. UHF radios working at 400 to 900 MHz give enough transmission capacity to transmit plans. Remote LAN radios working at 2.4 GHz enable machines to be associated into the mine's intranet framework, or even into the web for remote association. Remote LAN systems have extraordinary transmission capacity however are constrained to viewable pathway correspondence and distances as much as 2 kilometers. A portion of the constraints of remote LAN can be overwhelmed by fit systems in which each machine is a repeater. On the other hand a double framework can be introduced with UHF or VHF for the mission basic GPS amendment factors and other information reserved until the LAN association is established.

At the point when machines are associated with the intranet, downloading structures is a straightforward intuitive procedure. Intranet association additionally enables supervisors and engineers to sign in and see precisely the screen that the administrator is seeing, and along these lines answer any inquiries or concerns. Intranet associations for this reason can be installed on supervisors' vehicles.

GPS set out the Mining Industry as a quick and savvy instrument for overview. A moving to a great extent scene is the easygoing organization of mining techniques; the shovels and dozers will evacuate the coal and metal, the shovel and dumper will reshape the mine's air foil. The steady changes happenings in mining industry can be gotten to by ongoing GPS and heavy equipment operators are provided with the updated operating information. In add on, GPS systems give a rapid and exact solution for substituting and asseverate control points and by calculating the volume of material moved. By using advanced GPS technology heavy machines like dozers draglines can be assessed and used. By using Modern GPS systems we can also track and monitor the scenario and position of dump trucks, given reports to their targets, movements and speed covered per distance and also the amount of the truck‘s load. GPS live now a days is decorous for observing and bumping of haul trucks or drills and for giving grade assure on shovels. The data obtained can also be tied to a GPS to observe the location position of every equipment, in real-time. As GPS is an all-weather real time, frequently usable, economical and very exact positioning technique, will be having great array of applications in Indian mining industry. The potential areas for using GPS in the Indian coal industry include Surveying Various advanced surveying skills such as satellite remote sensing, photogrammetric, field surveying methods using digital theodolites, short-and long-range EDM tools such as Total Station, etc. are now usable a day[2]. The main advantages when using satellite-based GPS survey skills are: • GPS measurement does not need point-to-point inter-visibility, whereas the ancient survey devices used to allow measurement line of sight. • The GPS approach offers a point location in 3 D. We can get the horizontal and vertical position in one measurement of the point, where as in ancient old surveying, we need 2 operations one is horizontal traverse for plan metric control and the other is a level loop for height control. kilometres. It can also provide the very exact accuracy anywhere on earth, and also in any. Whether condition at any point or any temperature conditions. GPS offers many rewards relatively when we compare with conventional survey methods. As there will be no necessity for a rod person, each surveyor will work alone when required. GPS also needs very much less setup time rather than any traditional surveying equipment, so the team can use its time more effectively. It will also keep a much more conciliatory schedule and can actuate from one area to the next or from one seam to another when it is needed[3].

SOFTWARE SYSTEM:

• Truck queuing– Increased fuel consumption and decreased performance result in unnecessary truck queuing. Active engineering model provides validated optimization of truck assignments in real time, reducing truck queuing at loading and dumping sites. • Hanging time for the shovel / excavator– A shovel or excavator does not load the truck with time and money lost every minute. For each excavator, the proper mathematical model accounts for the number of trucks, automatically allocating trucks and increasing the hanging time. • Unrealized plant capacity and/or poor blends–Incorrect head feed grade may lead to reduced plant equipment efficiency and may also result in damage to equipment. Effective mathematical system maximizes production whereas on the identical time with regard to the constraints of material mixing. • Inefficient change of switch–inefficient change of operator holds machinery out of operation and reduces efficiency. • Unnecessary travel time–Unnecessary travel Results in waste fuel and running time when removing and breaking needless equipment. Through determining the best path between starting and end points and using the correct guidance system, it is possible to eliminate excessive travel time. effective Engineering model proactively manages and schedule equipment and personnel. • Misdirected loads–This practically throws money away from sending material to waste dump. Likewise, dumping waste in a crusher will cause expensive downtime and affect the value of the mixture. An efficient system continually reconciles the grade of mining material. • Uneven benches–Uneven benches require substantial rework of the support equipment to prevent damage to the equipment being transported. To avoid such damage, continuous monitoring of the elevation of the track is necessary. • Improper blast design–blast design must be unique to product strength in order to avoid explosive waste and fragmentation inappropriate. The efficient system optimizes the layout of the blast. Real-time machine guidance ensures plan-based drilling by operators [4].

This is the fully computerised Global Positioning System. This has been used in NALCO mines for the last few years. This is used to locate the Positions of different equipment‘s within the range of the satellite. There is a Satellite installed for this purpose. This has a particular range. There are several zones called Dark Zones which are out of the range of the satellite or is in a weaker part of it. The GPS Based Truck Dispatch System implemented at Panchpatmali Bauxite Mine has been a great success in achieving its objectives.

The basic actions that the truck driver needs to take are to inform TDS when the truck arrives at a shovel, when it is loaded, when a dump assignment is required, to confirm arrival at the dump and return to a request shovel. Other required input is that related to the condition of the truck being experienced, downs or delays the amount of fuel put in the truck, etc. Communication with the driver is via a 32 character digital display on the operator interface panel.

The shovel operator has same facilities as basically the truck driver, except that he is required to indicate to TDS information pertaining to the loaded, and

The nerve center of the entire operation is the open pit lookout tower. Here there are computer terminals in use, which serves a different function in assisting the lookout operator to control the mining operation.

The crusher operator's primary function is to tell TDS what ore stockpile he's tipping on and when he starts and finishes crushing a load. Within its linear programming calculations, TDS uses the latter information to determine the feed rate of trucks to the right crushers and thus the proper feed rate of trucks to the ore shovels. In order to optimize the cycle time of the network with minimal waiting, TDS determines the optimal inventory to dump for each specific vehicle.

Mine engineering personnel are responsible for the upkeep of the TDS system, particularly to consider the primary pit configuration data like haul routes, composite data, production equipment information, etc. As with computer operating systems, TDS has many configurable system parameters which affect the efficiency with which it operates. It is the responsibility of mine engineering personnel to ensure that these parameters are set to optimize the efficiency of the dispatching operation at all times[6].

All digital inputs of the TDS hardware capture key information like Engine Run Hours, Idle Hours, Over Temperature and Over Pressure, which will assist maintenance. Operators are provided with an easy to use interface. Operators may also provide with audio visual feedback with regard to messages from the base during loss of communication with the base, and GPS unavailability.
