DRILLING :
1) Drilling machine shall be fitted with dust suppression, collection and disposal arrangement.
2) Deep wetting of drilling zones shall be done by water sprinkling before starting drilling. 3) During the drilling operations the efforts shall be made to reduce dust
P a g e 12 | 14 generation by taking appropriate measures
BLASTING
1. Proper blasting whole geometry shall be designed.
2. Blast site shall be wetted before and after blasting operations are completed.
3. Only optimum quantity of permissible explosives shall be used so that the vibrations do not damage the structures/houses if the quarrying operations are close to human habitation.
4. Blasting shall be conducted only during favorable weather conditions and only during the day time and permissible hours.
5. The blasting operations shall be given publicity in the local area through Davandi and other available media so that local people become aware of the blasting activities being undertaken in the area.
6. The vibrations should be monitored periodically in consultation with the local Mining authorities.
7. The storage of the explosives and its transfer to and from the quarry area shall be strictly in accordance with the conditions listed in the permission granted by Explosives Department
5.2 WATER POLLUTION CONTROL
Garland drains will be provided around the working pits to prevent entry of rain water inside pit. Selection of waste dumps site will be in non-mineralized zone of mining lease area. Water will be collected in the mines sump after deposition of silts in the catch drain. The drain will be de-silted regularly and maintained properly.
5.3 NOISE POLLUTION CONTROL
The latest machinery will be used in mining and due care will be taken to minimize Generation of noise. Scheduled and preventive maintenance of all machines will be carried out periodically to keep the original condition of the equipment so that noise generation from them can be reduced and controlled. This will help in reducing generation of noise during working of machines.
Drilling will be carried out with sharp drill bits to reduce generation of noise during drilling.
Controlled blasting with adequate charge per hole will be practiced to reduce generation of noise.
Plantation will be done on the sides of approach roads, around rest shelter and workshop area. The plantation work minimizes propagation of noise.
Earmuffs will be provided to all operators and employees working at higher noise zones.
Periodical monitoring of noise level of mining machines in the mining area will be done with the help of noise level meter.
Training at regular intervals for use of personal protective equipment like earplugs
& earmuffs will be imparted to all employees. All the operators will be provided with earplugs & earmuffs.
P a g e 13 | 14 5.4 GREEN BELT
33% Green belts surrounding the ML area and along the permanent roads shall be developed with tree species having broad leaves, with minimum of three rows, keeping 5x5 m interval. Spacing in between the tree saplings shall be used for development of under growth. Mostly local varieties of plants are proposed to be planted to improve the soil quality with humus and carbon.

5.5 LAND RECLAMATION
The total mining lease area is 3.68 Ha Of this only 3.109 Ha will used for excavation.
This excavated area will be used as water reservoir. The rest of the area will be converted to green belt with two row plantation. The post mining Land use of the area will improve the overall ground water regime and green cover in the area which create the positive impact on environment and enhance the aesthetic beauty.

7.0 CONCLUSION
The surrounding inhabitants are mainly agricultural dependent. The frequent drought prone condition leads to migration of the people to other areas. Unemployment and Under employment are the main problems of the inhabitants. Opportunities for jobs in activities such as mining serve as a source of permanent livelihood. In order to access the mine approach roads are developed and/or maintained by the operating Company, which is also beneficial to the surrounding population. The village roads are usually strengthened for transportation of minerals. The mined out area is also becoming source of water for villagers as good quantity of water is stored.
Thus in the interest of mineral development and to improve the social conditions of the local habitants this project should be allowed after considering all the environmental aspects.
