District Survey report (DSR) will be prepared in every district foreach minor mineral. The District Survey Report will guide systematic andscientific utilization of natural resources, so that present and future generationmay be benefitted at large. The purpose of District Survey Report (DSR)"identification of areas of aggradations or deposition where mining can be allowed; and identification of areas of erosion and proximity to infrastructural structures and installations where mining should be prohibited and calculation of annual rate of replenishment and allowing time for replenishment after mining in that area". The District Survey report (DSR)will contain mainly data published and endorsed by various departments andwebsites about Geology of the area, mineral wealth details of rivers, detailsof Lease and mining activity in the district along with sand mining andrevenue from minerals. 3 4 1. INTRODUCTION The Andaman and Nicobar Islands, located in the south-eastern part of the Indian mainland geographically, float in splendid isolation in the Bay of Bengal. It lies between Latitude 11.7401°N and Longitude 92.6586°E. This Union Territory is a chain of around 572 Islands and Islets. Most of these Islands (about 550) are in the Andaman Group, 28 of which are inhabited. The Nicobars comprises of around 22 main islands (10 inhabited). The Andaman and Nicobars are separated by the Ten Degree Channel which is 150 Km wide and are southward extension of Arakan Yoma Range (Myanmar) [ArakanYoma, itself is an extension of Purvanchal Hills]. Port Blair,the capital and gateway to the Islands lies in South Andaman Island and falls under South Andaman District. It offers water-based activities like snorkelling, scuba diving, sea-cruises, and glimpses of the history and culture of the region. The Andaman Islands are an Indian archipelago in the Bay of Bengal. Approximately 300 islands are known for their palm-lined, white-sand beaches, mangroves and tropical rainforests. Coral reefs are mostly surrounded in Nicobar Islands. The indigenous people of Andamans were the Great Andamanese, who collectively represented at least 10 distinct sub groups and languages; the Jarawas, the jungle (or Rutland Jarawa); the Onge; and the Sentinelese (the most isolated of all the groups). The indigenous people of the Nicobars (unrelated to the Andamanese) have a similarly isolated and lengthy association with the islands. There are two main groups, the Nicobarese, or Nicobari living throughout many of the islands; and the Shompen, restricted to the interior of Great Nicobar. The Islands are having a tropical climate. The South-west Monsoon sets in Andaman Nicobar Islands towards the end of May and the North-east Monsoon in November. The Barren Island (only active volcano in India) and Narcondam Islands, north of Port Blair, are volcanic Islands. These islands are also having remembrance of freedom fighting days and historically significant landmarks viz. Cellular Jail, Netaji Subhas Chandra Bose Island, Viper Island, Hopetown and Mount Harriet. The Andaman & Nicobar Islands have a Geographical area of 8249 sq.km, out of which an area of 7171 sq.km (87%) is notified as forest under Indian Forest Act, 1927 and this rich Eco-system support a variety of Flora and Fauna with in itself. Out of the total area 7171 sq.km notified as forest 70% is totally protected in the form of Tribal Reserve, Biosphere Reserve, National Park and Sanctuaries and further in the form of mangrove conservation working circle and protection working circle even within the area covered by Working Plans. 5 The Andaman and Nicobar Islands have been declared as two of the218 endemic bird area of the world. As many as 270 species and sub-speciesof birds have been reported existing in these islands, 106 of them beingendemic. The Andaman Wood Pigeon, Andaman Padauk and Dugong aredeclared as State Bird, State Tree and State Animal respectively. There are about 96 Wildlife Sanctuaries, nine National Parks and one Biosphere Reservein the islands. A mini-zoo exists in Port Blair for exhibiting unique animalspecies of these islands. A Biological Park is also developed at Chidiyatapu foreducating people and creating awareness among them for wildlife. Theseislands are blessed with the bounties of both south-west and north-eastmonsoons. There are many direct flights from Chennai, Delhi and Kolkata to Port Blair. Most of the inhabited Islands are interconnected by helicopters. Recently, sea planes have alsobeen proposed in limited number of destinations. 6 2. Overview of Mining Activities Mining site at Madhupur (Diglipur Tehsil), Shyamnagar (Diglipur Tehsil), Harinagar (Mayabunder Tehsil) and Panchawati (Rangat Tehsil) areidentified mining area at North & Middle Andaman District. a. Madhupur Area at Diglipur An area 2.00 ha of Govt land bearing Survey No.49/P recorded in Form AM as hilly land at village Madhupur is identified for conduct of quarrying without the use of explosives. The above proposed quarry consists of total 08 blocks with each block of area 0.25 ha. Marked as –Block A,B,C,D,E,F,G & H. The quarry plan for the above quarries have been already approved by the Competent Authority. b. ShyamnagarArea at Diglipur An area 1.00 ha of Govt land bearing Survey No.102/1/P recorded in Form AN as hilly land at village Shyamnagar is identified for conduct of quarrying without the use of explosives. The above proposed quarry consists of total 04 blocks with each block of area 0.25 ha. Marked as –Block A,B,C&D. The quarry plan for the above quarries have been already approved by the competent authority. c. Harinagar Area at Mayabunder An area 2.00 ha of Govt land bearing Survey No.4/1/P recorded in Form AM as hilly land at village Harinagar is identified for conduct of quarrying without the use of explosives. The above proposed quarry consists of total 08 blocks with each block of area 0.25 ha. Marked as –Block A,B,C,D,E,F,G&H. The quarry plan for the above quarries have been already approved by the Competent Authority. d. PanchawatiArea at Rangat An area 01.50 ha of Govt land bearing Survey No.49/P recorded in Form AM as hilly land at village Panchawati village is identified for conduct of quarrying without the use of explosives. The above proposed quarry consists of total 06 blocks with each block of area 0.25 ha. Marked as –Block A,B,C,D, E &F. The quarry plans for the above quarries have been already approved by the Competent Authority. Altogether, in North & Middle Andaman Island 26quarry blocks have been identified. The selected area haslimited spatial extent, recognizable through topographic expressions, smallhillocks, mounds, ridges over shorter intervals having narrow depressions etc.The extraction from this area would be of minor minerals only i.e. earth andstone boulders. Physical inspection has revealed that there are sufficientdeposits of these minor minerals at the site. Quarrying in this area is not exactlymining but is more like digging and levelling. This would ultimately result ingetting flat land bounded by hillocks having a gradient of 45 degree angle. 7 The selected quarry area was inspected by a group of Govt. officials at different locations. Based on the levels taken, plots of size 0.25 Ha have been carved. All the 26 blocksare having the size of 0.25 Ha. 3.
