Prof. K. Pathak, Department of Mining Engineering IIT Kharagpur-721302 [email protected] Mineral Production is bound to increase in the coming years! construction aggregates is expected to rise 2.9% annually, reaching almost 28.7 billion tones by the year 2013. The power generation demand is going to increase the demands for coal, steel and copper. India aims to add about 100 gigawatts (GW) of power generation capacity by early 2017. April 1, 2010, India's total installed generation capacity stood at 159.40 GW. Only 6 percent of India's total power mix now comes from renewables. India is Asia's third-largest power producer coal imports have grown rapidly India's coal demand was 597.5 million metric tons in the fiscal year to March, 2010. India’s refineries processed 186.562 barrels per day of oil and local gas output was 47.57 billion cubic meters. With about 57 Mte of steel production (4.64 % of wolrd production in 2009) India and with expected growth rate the domestic iron ore consumption will be 190 Mte as per National Steel Policy. (India’s iron ore reserve is about 252 Bte in 5 Zones) The mineral sector has shown a positive growth of 9.75% during the current financial year i.e. April- March 2009-10 as compared to that of the previous year. The mineral production in March 2010 was higher by 10.96% as compared to that of the corresponding month of previous year India's mineral production from mining and quarrying sector in March 2010 registered a growth of 14.41% compared to that of the preceding month. Mineral Business Growth should be compatible with facilities for Mineral Movements This higher level productions are distributed in various geographical ‘Mineral belts’ and their users are located at different places requiring multiple handling and transporation of bulk materials. Mineral Belt Location Minerals found Coal, iron ore, manganese, mica, bauxite, copper, kyanite, chromite, beryl, apatite etc. This region posses India's 100 percent Kyanite, 93 percent iron ore, 84 percent coal, 70 percent chromite, 70 percent mica, 50 percent fire clay, 45 percent asbestos, 45 percent china clay, 20 percent limestone and 10 percent manganese. North Eastern Peninsular Belt Chota Nagpur plateau and the Orissa plateau covering the states of Jharkhand, West Bengal and Orissa. Central Belt Manganese, bauxite, limestione, marble, coal, gems, mica, Chattisgarh, Andhra Pradesh, graphite etc. exist in large quantities and the net extent of Madhya Pradesh and the minerals of the region is yet to be assessed. This is the Maharastra. second largest belt of minerals in the country. Southern Belt Karnataka plateau and Tamil Ferrous minerals and bauxite. Low diversity. Nadu. South Western Belt Karnataka and Goa. North Western Belt Rajasthan and Gujarat along Non-ferrous minerals, uranium, mica, beryllium, the Aravali Range. aquamarine, petroleum, gypsum and emerald.

(2006), "Mineral Resources", India: A Comprehensive Geography, pp. 630-659, Kalyani Publishers, ISBN 812722636X. Distribution of locations of Bulk material handling loads in India 4 Ports and Road/ Railway Connectivity for Rapid Movement of Exported or Imported bulk materials is of paramount importance for India’s economic growth INDIA: Transport Sector Key Statistics Transport Sector Bottleneck Units As of 2009 Length of Roads Km. 3,516,452 Main Roads Km. 666,452 Paved Roads % 47.3 Access to All-Season-Roads % 61 km/1,000 sq. km. Km. 1115 Road Density Rail Track Length No. of Ports Turnaround time 63,327 199 Days 3 Airports 125 International 11 Roads are congested and of poor quality Rural areas have poor access and mines are in rural and forest areas The railways are facing severe capacity constraints, delays are common. Besides they are easy target of extremists. Urban centers are severely congested, unplanned urbanization leaving no/little scopes for facility expansion Ports are also congested lack rapid bulk handling facilities Road and rail monitoring and maintenance are not using advanced technology No attempts visible for maintaining roads and standardizing trucks capacity to optimize energy efficiency At present in most cases only two trains run between two stations with the present signaling system, with advanced technology it may be possible to run 6/8 trains between two stations while ensuring 100% safety. Scopes of using higher capacity wagons (including lower tare load/ higher-volume wagons depending on commodity carried), track renewals enable higher axle loading on select corridors to be explored A major question of near future How to handle movement of large quantity of bulk materials economically and environmentally friendly? Major modes of ore transport practiced in India are Will Need Modernization like advanced Wagons, Control system, safety monitoring to cater large scale transport of iron ore, coal, alumina, Cu concentrate etc. • RAILWAY • ROAD • WATER WAYS • COASTAL SHIPPING • PIPE LINE Inadequate and poor quality roads will have to be transformed rapidly. Caters 65 % of all freight and 80 % of passenger Not used effectively Bulk ports are mainly for export import Minimal use, almost nil other than crude oil transport. Not many slurry pipe lines. RAIL TRANSPORTATION ISSUES & CHALLENGES Inadequate rail capacity for handling both domestic requirements and to handle bulk materials for export and import. Lower Haulage capacity leading to higher lead time Matching demands of passenger and freight train Frequent Changes in rail freight affects the planning of mineral producers and consumers Threat of exorbitant Punitive charges for overloading leads to under loading of rakes and thus loss due to dead freight payment. Lack of rail connectivity to ports and long time lines for rail projects. Critical situation during natural but anthropogenically induced calamity: Mumbai Flood How to protect transportation systems from such situations is a technical challenge India has scope to improve inland water ways and ports. INLAND WATER WAYS • Almost not used for Bulk material transport • East and North East India can explore its economics Waterways……………. India has a large number of perennial rivers and a very long coastline of 6100 km. Types :- (a.) Inland water transport (b) Ocean water transport National Waterways :1.The Ganga river - Allahabad to Haldia - 1620 km. 2. The Brahmaputra river - Sadiya TO Dhubri - 891 km. 3. The West Coast Canal - Kollam to Kottapuram - 14 km. 4. The Champakara Canal – Kerala -13 km. 5. Udagmandalam Canal - Kerala -22 km. Major Sea Ports :- At the time of Independence - 5 sea ports Sea ports at West Coast Seaports at East Coast 1. Kandla 1. Tuticorin 2. Mumbai 3. Nhova Sheva (Jawahar Lal Nehru) 4.Mormugao 5. Mangalore 6. Kochi 2. Chennai 3. Ennore 4. Vishakhapatnam 5. Paradip 6. Haldia PORT INFRASTRUCTURE: POSSIBLE SOLUTIONS TO CHALLENGES • Port capacities to be augmented to gear up for higher exports of all commodities • Modernization of all machinery and mechanization • Develop higher drafts to take advantage of handling vessels of higher capacity with lower unit freight costs. • Compress time lines in port projects implementation • Matching port capacities with rail-road infrastructure to remove bottlenecks • Develop facilities for railway rakes to go inside the ports for unloading / loading and dispensing with interchange/exchange yards to reduce cycle time. • Seamless movement in/out of port for both road and rail to cut down waiting time and increase throughput.

Steel producers intervention in development of ports and berth facilities is needed for improving productivity, turn around time, capacity to handle larger vessels and other operational parameters of efficiency. New technology need to be investigated to meet the transportation needs of India’s Mineral Sector RopeCon Conveyor: The Latest Innovation in Bulk Material and Unit Load Handling- a combination of conveyor belt and aerial ropeway RopeCon is a long-distance continuous conveyor system suitable for the transportation of bulk materials and unit loads of any kind. This product is the result of well-proven transport technology combined with Doppelmayr's decades of experience in the ropeway industry. • • • • Sinberi Gold : Papua New Guinea Application areas: Single conveyor lengths up to 20,000 m Capacity up to 10,000 tonnes/hour Easy traversing of streets, railway tracks, rivers and other obstacles Tower spacing up to 2,000 m Jamaica, bauxite "Mt. Olyphant", Jamaica "Zöchling“, Austria Examples of Use of RopeCon "Tüfentobel", Switzerland, St.Gallen "Lenzing", Austria (for wood chips) "Strengen", Austria Scopes of RopeCon in India Application of this system can be useful for transport of iron ore from Barbil area of Orissa to the port for exporting. At present the NH 33 is highly congested due to road transport of the ore. Traffic jam in the area causes extreme problems leading to wastage of diesel and emission of greenhouse gases. Long time is wasted on the transport. A techno-economic feasibility can be studied for a centralized export depo at a suitable receiving station near Joda and a ropecon terminal near port. Even an integrated ship loading system can be examined. Feasibility studies may also be carried out for Tata Steel’s new mines at Khanband for transportation of the processed ore from the proposed processing plant to steel plant at Tata Nagar. Modern technology is needed at Toll Gates and Weigh Bridges To meet the projected mineral movements on roads along with the expected increased traffic density, toll gates and interstate boarder gates will be nightmare in future if it is left like the present. Toll gates must be electronic. Automatic identification of moving vehicles in the gates and deduction of prepaid toll from the special deposit system linked with bank would save some vital time. Electronic vigilance and surveillance of traffic movements will have to be used for elimination of traffic jams on the highways. The weigh bridges will have to be a matter of the past with introduction of on board weighing and RF based data transferring system. Illegal mining, theft of produced coal through the loop holes of manual security system will be eliminated by introduction of tracking ssytem. To solve the challenges of Bulk Material handling associated with growth in mineral sector RESEARCH AND DEVELOPMENT NEEDED IN MANY AREAS……. • RS GIS For Bulk Material Handling • Developing power generating road • Safety in Bulk Material Handling • Pollution control in Bulk Material Handling • Assessment of energy demands • Energy efficiency enhancement in Bulk Material Transport • Alternative technology development for bulk material handling • Techno-economic modeling for bulk transports • Facility planning and site locations for bulk material handling • Logistic planning • Supply-chain management for bulk material handling Research needed….. • Initiation of feasibility study for alternative system: Detailed techno-economics Truck Ramp Transfer Point Unloading/Reloading Bin Truck Ramp Transfer Point Conveyor Crusher Plant Combination System Mobile Slope Conveyor Some systems that may be in India in near future Go Green: Closed Belt of Pipe Belt Mobile Grasshopper Conveyor : Eliminate Trucks and Diesel A GREEN BULK MATERIAL HANDLING CONCLUSION • • • • • • Rail ways need to initiate Designing / modifying tracks and rolling stock to higher axle load will increase throughput Usage of lighter material like steel in place of iron for rolling stock could increase tare to pay load ratio to 1: 3.4 thereby increasing quantity hauled/rake Expediting facilities for manufacture of higher axle load wagons , new technology bogies , couplers , draft gears and other equipment to get rolling stock suitable for 30.0 - 32.5 Tonne axle load . Development of rapid loading unloading system Use state-of-the-art technologies for forecasting rainfall, measuring runoff, traffic operating systems. On-line flood forecasting and traffic operation system(s). Steps to be taken to improve road density and quality Industry status will have to be accorded to road transport operators Roadside amenities and Emergencies services will have to be improved urgently Development of high load carrying roads and vehicles will enable movement of higher quantity per vehicle Rail connectivity to ports like Belikeri, Karwar, Krishnapatnam needed to avoid more truck movements and diesel consumption and CO2 emissions. Participation by the steel industry in creation of railway Infrastructure would be necessary Thanks All are doing good with their best capacity but better options are always there and we must study, investigate, experiment and implement to manage the changes associated with growth.
