CHAPTER-3
TOPOGRAPHY AND GEOLOGY
(i) Topography:
The lease area is falling in the Mahanadi river bed on western bank. Since, the sand area falling in the river bed, the general surface level of the lease area is comparatively lower than the surroundings. The general surface level is around 270 mRL on the river bank and in the lease area on river bed the surface level is about 264 mRL, thus the area is about 6 m below from the general surface level. The flow direction of River is from south west to north east direction.
(ii) Regional Geology –
The River Mahanadi is start from Granites of Archaean age and thereafter flowing through the Chhattisgarh Basin, which are belonging to mainly Raipur and Chandrapur Groups of Chhattisgarh Supergroup. Thus, almost the River length is flowing through the rock formations of Chhattisgarh Supergroup. The alluvium forms a narrow belt along the Mahanadi River, comprising, sand, gravel, clay and silt in varying proportions. The characteristics features of this valley fill alluvium is, its occurrence along the left bank of the River attaining a thickness ranging from 15 to 40 m. The intera-cratonic Chhattisgarh Basin is crescent shaped and covers about 33,000 sq km area in almost the center of the Chhattisgarh and adjoining parts of Orissa. The basin has a maximum length of about 300 km along ENE-WSW direction. The maximum thickness of sediments is estimated to more than 2 km and is epi-continental or stable shelf type. The sedimentary rocks and associated formation which is occurring in nearby villages is forming a part of Chhattisgarh Synclinorium. The general trend of Chhatisgarh basin is NE to SW.

(iii) Local Geology: River & Drainage - The lease area forms the river bed of Mahanadi River which flow towards north east direction.
Transportation of Sand - The sand is not a insitu materials but being carried out by flowing water during the monsoon every year from various catchment areas of the river and getting accumulated at convenient locations like bends, escarpments etc. and as such the sand of the lease area is a carried material brought from various locations and getting accumulated at convenient places in the flow direction of the River. The size of the accumulated sand varies due to the time factor taken by the river as well as the quantity of flow water. The depositions normally take place on winding course (bends)/meanders/loops/circuitous journey (of a river) in flow direction.
The maximum and minimum width of River bed is about 1580 m and 1376 m respectively and the maximum and minimum width of the mining lease area is about 285 m and 140 m respectively.

CHAPTER-4
RESERVES
Give estimates of geological reserves alongwith grade under proved, probable and possible categories by standard method of estimation supported by analytical data.
The lease area is 40,000 sqm and the thickness of the sand bed is more than 6 m (Source: Information by Sarpanch Gram Panchayat Kumhari) The proved thickness of sand bed is considered 3 m and below this, further 3 m thickness has been considered as probable thickness. As the replenishment of sand in monsoon season is a regular process. Based on the last five years observation, it’s experienced that the average 3 m sand has been replenished every year.
The parameters considered for reserve estimation are as under: a. The general surface level of the lease area is 270 mRL which falls on river bed. b. Sand deposit area has been marked on 1:1,000 scale. c. The topographical mapping was carried out at 1 m contour intervals. d. The process of accumulation of sand is a continuation process thus every year during rainy season in this area. e. The reserve has been estimated by area of influence method. f. The proved thickness has been considered as 3 m g. The probable thickness has been considered as 3 m h. The B.D. of sand (ordinary) has been considered as 1.7. i. The lease area has been recently surveyed on dated 24/08/2016. j. The reserve of the river bed can be estimated by the available sand area in the total lease area and multiplied by the average estimated thickness.

Total Sand Resources area as under:
(i) Total Proved Mineral Reserve: The lease area is 40,000 sqm and thickness of ordinary sand is considering 3 m from surface. Hence, the estimation of total mineral resources is as under:
Sand bearing area Thickness of Volume B.D. Tonnage sand bed (sqm) (cum) (T) (m)
40,000 3 1,20,000 1.7 2,04,000
(ii) Total Probable Mineral Reserve: Further 3 m thickness has been considered for this category. Hence, the estimation of total mineral resources is as under:
Sand bearing area Thickness of Volume B.D. Tonnage sand bed (sqm) (cum) (T) (m)
40,000 3 1,20,000 1.7 2,04,000
The estimation of blocked out resources: The lease area is already 55 m away from the river bank, where mining operation will restricted. Hence, no reserve will be blocked.
Thus, the reserve and resources of sand (ordinary) is as under:
Category Total Resources Blocked Resources Mineable Reserve 1,20,000 cum 1,20,000 cum Proved --- (2,04,000 T) (2,04,000 T) 1,20,000 cum Probable ------(2,04,000 T)

Anticipated Life of the Mine:
The Proved Mineral reserves (ordinary sand) of 1,20,000 cum (2,04,000 tonnes) and the proposed production rate of about 1,00,000 cum (1,70,000 tonnes) per year. Due to continues sand deposition in the area during rainy season there will not be much depletion in the reserve of sand, hence reserve is likely to be remain same every year and in future also.

CHAPTER- 5 (a) DEVELOPMENT AND PRODUCTION PROGRAMME
Maximum depth of removal of ordinary sand/bajri (3 mtrs from surface or up to water table/bed rock whichever is less)
The depth of removal of sand will be restricted upto 3m.
Outline briefly, year wise development and production for first five years including precautions to be observed to prevent haphazard excavation of pit, scattering of waste and sub-grade mineral and avoidable loss of mineral in ground.
The five years of the mining plan period will be 2016-17 to 2020-21.
The proposed method of mining was open-cast mechanized by using excavator-tipper combination. The excavation of sand and loading of the same will be carried out by excavator of two cum capacity. The sand will be extracted by phased manner, two stages maintaining pit slope less than 300.
The excavated sand will be directly loaded into truck/tipper/dumpers.
Since, there will not be pit formation, hence development of pit is not considered and sand is deposited directly in every monsoon. As mentioned previously, lease area located within the river bed and there will be continuous deposition in the area every year during monsoon and sand will get refilled wherever mined out area during the year. So the mining activity need not be properly lined out as seen the other mineral cases. In the case of sand mining, the mined out areas will get refilled during monsoon and again mining can be carried out in same location.
Since, the working will be carried out only about 8 months and working days considered as max. 200 days in a year.
No drilling and blasting is required, since the sand is a loose / semi-compact / incompact formation.
The production of sand has been proposed to about 1,70,000 tonnes (1,00,000 cum) per annum.
Total lease area is 40,000 sq m (4.00 Ha), and the whole area is available for mining.
Total mineable reserves of sand is 1,20,000 cum (2,04,000 T) thus per hectare about 30,000 cum (51,000 T) sand is available for extraction in a season.
Considering the replenishment of sand and available reserve, about 1,00,000 cum (1,70,000 T) sand can be safely extracted per year.
Thus, annually 1,00,000 cum (1,70,000 T) in 4.0 Ha area or say about 25,000 cum (42,500 T) sand per hectare per year can be extracting from this site.

Requirement of excavator / loader for loading of ROM.
S. No. Particulars ROM 1 Production during a year 1,00,000 cum
2 Excavation per day (taking 200 days) 500 cum 3 Bucket capacity of Excavator(C) 2 cum 4 Fill Factor (F) 0.9 5 Swell factor for broken mass (S) 0.76 (76%)
6 Overall efficiency = (Availability x utilization x operating 0.46 (46%) efficiency) (n) 7 Cycle time in seconds for loading by excavator 2 minutes (t) 120 seconds Formula: Ah = hourly production of 1 cum excavator 8 = (3600 x C x F x S x n)/ t Say 19 cum = (3600 x 2 x 0.9 x 0.76 x 0.46)/120 = 18.88 cum 9 Handling required per hour = 500/ 8 (hours) = 62.5 62.5 cum
10 Therefore nos. of excavator required = material handling / Say 3 nos. hourly production = 62.5 / 19 = 3.28
Haulage and Transporting:
For transportation of loadable sand from lease area to consumers, mostly 20 cum capacity dumpers/tippers will be utilized.
S. No. Particulars ROM 1 1,00,000 Production during a year cum 2 Excavation per day (taking 200 days) 500 cum 3 Dumper capacity 20 cum 4 One dumper can carry (as safety measures) 18 cum 5 Nos. of trips required per day (500 / 18 = 27.77) Say 28 trips Note: Transportation of sand will be carried out by user; hence there is no requirement of truck, tipper/dumper to the lessee.

CHAPTER-6
RECLAMATION PLAN
Describe briefly the year wise reclamation plan, giving the proposed plantation programme, scope of backfilling of worked out pit.
The river bed material normally consists of sand (< 2 mm size), small gravels (> 2mm < 20 mm size) and gravels (>200 mm size). These materials comes down mostly rolling over the river bed from steep stream/river slopes and settles down when the velocity of flowing water decrease at the confluence of hilly & plain areas. The deposition of these materials diverts the river flow in different direction thus forming islands varying sizes. These islands are dynamic in nature and their location is not fixed. The river flow may strike left or right bank of the depending upon the rate of discharge, type and volume of river bed material (RBM) brought from a rain storm etc. this phenomenon may not become significant in a year or two but has its effect over longer period of time.
Principally the extraction of annual quantity of RBM should not be exceeding the RBM brought during the monsoon of that year. However, the recommended quantity of extraction of RBM is limited to 30 to 90% of the RBM brought during the monsoon.
Methodology of extraction of RBM is more critical / relevant than quantity of extraction of RBM. Improper method of extraction of RBM of even less quantity may be more critical.
As the replenishment of sand in monsoon season is a regular process. Based on the last five years observation, it’s experienced that the average 3 m sand has been replenished every year.
Development works undertaken on river/stream bank becomes vulnerable due to frequent striking of river/stream flow on river bank. It therefore becomes necessary to guide the flow to the centre of the river/stream. Extraction of RBM with proper and careful method is one of such measures to channelize the flow to the centre so as to avoid stream bank erosion. The other measures are treatment of catchment with suitable soil and water conservation measures so that the soil/gravel are not carried out down from their location; following drainage line treatment viz spurs, retards, wattling, planting of suitable vegetation on river bank etc.
Plantation will be carried preferably on the River bank and also along the road used for transportation or the area proposed by the Gram Panchayat.
