Impact of the pollution abatement measures taken on conservation ofnatural resources and on the cost of production

Following abatement measures have been adopted at the Nongtrai Limestone Mine:The mining at Nongtrai limestone Mine of Lafarge Umian Mining Private Limited(LUMPL) is carried out by using advance drilling and blasting techniques. Drillingprogram in mine is fully related to the production requirement by conventionalmethod.

• Blasting is carried out with proper planning and utmost safety aspects under the strictsupervision of blasting expert holding first/second class Manager's certificate.Blasting is performed only during the day time as per norms and conditions. It lastsfor a few milliseconds to less than 2 seconds.The non electric (NONEL) shock tube initiating system and noiseless trunk line delay(NOT) are used on the top for hole to'hole delay. In addition, pre-splitting techniqueis used before the main blast. This helps in creating a barrier thus reducingtransmittance of ground vibration waves.

• A continuous wind monitoring system has been installed to know hourly winddirections. Based on prevailing wind directions at the time of blasting, the direction ofdetonation is adjusted. This results in maintaining lower transmittance of any noiseand dust levels.In order to ensure that the ground vibrations remaining within low levels, LUMPLmonitors ground vibrations with every blast using seismographs imported fromCanada. Based on the results further modification in blasting is done from time totime. As per the monitoring results, the peak particle velocity of 0.23-3.78 mm/sec isobserved at distance of 200 to 300 m, which is much lower than the Indian Standardlimits as prescribed by DGMS(Tech.) Circular NO.7dated 29 September 1997).LUMPLalso use blast muffing mat as and when required to arrest any fly-rock. Blastmats reduces noise, shock and eliminate escape of any flying debris.

• No secondary blasting is done this is eliminated altogether with the use of hydraulicrock breakers.Provision of bag filters on crusher to minimize air emissions from the crusher.To control fugitive dust emissions during transportation of mined limestone throughdumpers, an Automatic sprinkling system installed along the haul road, water foggerin dump hopper and LBCwhich operates successfully.A greenbelt is maintained all around the mine site and plantation is done in thesurrounding area, which cools the area and acts as a barrier for maintaining low dustand noise in the surroundings. LUMPLhas planted a total of 27518 local plant saplings(with 70% survival rate from 2004 to March 2014).A continuous wind monitoring system has been installed to know hourly winddirections, rainfall, temperature and humidity.5 nos. of Sewage Treatment Plant (STP) and 1 no. of Effluent Treatment Plant (ETP)are operational.Rain water harvesting system constructed at two locations Le. the roof top of thetransit camp area and roof top of the office area. Water being discharge and stored ina separate tank for reuse.Study of ground water management carried out by the installation of vibration wirepiezometer' in three locations .Ground water being monitored on monthly basis withthe help of this equipment.

PART - IAny other particulars for improving the quality of the environment

Besides maintaining greenbelt around the limestone mine, LUMPL constructed aborder fencing all around the sinkhole to conserve, preserve and improve ecology ofthe area.

• To create environmental awareness and natural resource conservation LUMPLcelebrates World Environment Day every year.
