Such rivers generally have shallow and gradual incision. The Maini River exibited maximum incision up to 5m and flowing from SSE to NNW with river meanders and braiding are major regional topographic features that represents gentle slope due NNW. The proposed sand mining is located in the river bed of river Maini. The topography of the notified area is almost flat. Notified Sand mine area is geologically situated in the bed of Maini River in Kanker district predominantly comprising older granites, exposed forming bold and rugged topography represented by high hillocks and undulatatory terrain. Part of the area is peneplained, weathered and extensively occupied by the alluvial sandy soil cover ranging from 0 to 5m. Notified sand mine area is geographically situated in the river bed of Maini. In eastern part of almost horizontally bedded Chhattisgarh basin comprised of the equivalent of dongargarh granite of Palaeo Proterozoic age. Rocks of dondargarh granite formation are forming bold and rugged and gently southerly dipping topography in east of the river. The dondargarh granite formation is almost horizontally bedded, weathered and extensively occupied by the alluvial soil cover ranging from almost 0.5 to 4 m. Sand is deposited annually during the monsoon, which is mostly derived from the older rocks exposed in southern parts of the area. Sand of the area doesn’t allow exploration and mining by the conventional methods, owing to the unconsolidated nature of the sand dominantly comprising fragments of quarts, feldspar. Therefore, the anticipated reserves can only be classified in Recognized Resources Category. Dongargarh granite occurs as batholiths covering an area of about 8000Km2 in rajnandgaon-Kanker-Bastar and Dhamtari disrtricts forming the central part of Bastar Province. The proposed sand mine in situated at the Maini River bed, which originated upstream terrain near Nagri-Sihawa. The Mahanadi River main River of Chhattisgarh. It has large catchment area and spread in over 30,000 km2. The river bed comprised of unconsolidated alluvial placer deposit of sand and bajari found along the river bed. The rock formations thrusting invasion of Mahanadi is within the dondargarh granite formation of the Chhattisgarh Super Group rocks of dondargarh granite formation are farming bold and nugged and gently NNW dipping topography in eastern part of the river. The dondargarh granite formation is almost horizontally bedded without significant exposurs. The formation around the area are weathered and Group Formation comprising Gluconitic arenites, arkose gritty waks arenite and comglomerate. Paleoproterozoic Dongargarh Granitoids Granite and Equivalents Archaean Basement --------- Not Seen -------- 4.0 ESTIMATION OF RESERVE 4.1 Estimation of reserve: Unlike other mineral deposits, sand deposits are not in-situ deposits. The deposition of sand takes place every year during monsoon. The amount of sand sediment deposition in a particular river stretch may vary year to year depending upon a number of factors like rain fall in the catchment area, bed slope, amount of sand excavated from that area etc. Also the thickness of the sand bed in a particular stretch of a river is not of uniform thickness. So the methods of reserve estimation generally used for estimation of other mineral deposit which are in situ deposits cannot be used to estimate the sand reserve. Sand deposition in the area is not of uniform thickness, the thickness of the sand bed varies from 4.0 m to 6.0 m. The water level in the proposed mining area goes up to 3.0-4.0 m below the general sand level in the area during summer. The reserve of sand in the proposed mine is estimated based on the following facts and assumptions: 1. The lease area is 2.0ha or 20000 m2. Average width of the river is 120 m, Average length of lease area is about 400 m, and average width of notified area is about 50 m. 2. Sand deposition in the area is not of uniform thickness, the thickness of the sand bed varies from 4.0 m to 6.0 m. In most of the area it is more than 5.0 m. So, the average thickness of sand bed is considered to be 5.0 m for reserve estimation. 3. Minable reserve is estimated after leaving a layer of 1.0 m along the river bed 4. As per distance certificate given by Mining office it seems that river bank to lease area is 10m. Considering the above facts and assumptions, The present sand reserve in the lease area 20000 X 5 = 100000 m3 Minable reserve (av. thickness 2.0m) 20000 X 2 = 40000 m3 4.2 Annual Replenishment of Sand in the Lease Area: As per the Ministry and Environment and Forest OM No. J-13012/12/2013-IA- 1I (I) dated 24.12.2013, the annual replenishment of the sand in the lease area should be sufficient to sustain the mining operation at level prescribed in the Mine plan. The replenishment of sand depends mainly upon the catchment area of the river, annual rainfall in the catchment area erosion of rocks in the catchment area etc. The proposed area falls under the river bed of Maini River. As stated earlier, the proposed area for sand mining falls under the river bed of river Mahanadi. It has a large catchment area. The average rain fall of the catchment area of the river varies from 4000-5000 mm. All these factors indicate that the annual sediments replenishment capacity of the Maini is good enough to sustain the proposed production. 4.3 Anticipated life of the mine: As per the Chhattisgarh Minor Mineral Rules, 2015 There is no provision in the Chhattisgarh Gond Khanij Ret Ka Utkhanan and Vavsaya Viniyaman Nirdesh 2006 and said rules regarding grant of lease for a fixed period as in case of other mineral minerals. As the quantity of sand that will be mined every year will get replenished every year during monsoon, the sand reserve will not get depleted. 5.0 DEVELOPMENT AND PRODUCTION PROGRAMME 5.1 Development: The mine is a very small mine and does not require much development work. Only a ramp of mild gradient of 1 in 15 to 20 will be constructed from approach road at the river bank to approach the mine. The excavation of sand will be strictly carried out as per the restrictions imposed by Chhattisgarh Minor Mineral Rules 2015, Chhattisgarh Gond Khanij Ret Ka Utkhanan and Vavsaya Viniyaman Nirdesh 2006 and the additional conditions imposed by Govt. of Chhattisgarh vide Gazette notification dated 1.11.2013 and as the Ministry and Environment and Forest OM No. J- 13012/12/2013-IA-1I (I) dated 24.12.2013. The Government of Chhattisgarh has imposed the following restrictions on river bed sand mining vide Gazette notification dated 1.11.2013: 1. Mining shall not be carried out within 100 m of any bridge/ National Highway/ State highway. 2. Mining shall not be carried out within 50 m of any natural water recourse, dam etc 3. Mining shall not be carried out within 3.0 from the banks of the river 4. Mining shall be carried out up to maximum 3.0 m depth or bed rock in the river The Ministry and Environment and Forest OM No. J-13012/12/2013-IA-1I (I) dated 24.12.2013 imposed the following restrictions on river bed mining. 1. The mining activity shall be done manually. 2. The depth of mining shall be restricted to 3m/water level, whichever is less. 3. For carrying out mining in proximity to any bridge and/or embankment, appropriate safety zone shall be worked out on case to case basis to the satisfaction of SEAC/SEIAA, taking into account the structural parameters, location aspects, flow rate etc., and no mining shall be carried out in the safety zone so worked out.
