CODE OF PRACTICE FOR PRESERVATION OF COAL QUALITY FROM MINING FACE TO SIDING

CODE OF PRACTICE FOR PRESERVATION OF COAL QUALITY FROM MINING FACE TO SIDING

Quality is an important aspect for our consumers. As our consumers such as NTPC, Kaniha are very conscious in this regard. Under ISO 9001/14001 costumer satisfaction is an important criterion for surviving any industry. Since our company is also competing in free market economy so it is very essential for us to preserve the quality from grass root level. The code of practice will help us to identity any deficiency or area of improvement by which we may solve our problems and achieve our goal by supplying coal with assured quality.

1.0   (A).Coal Bench In-charge of conventional face shall ensure that the face shall be cleaned before cutting by Dozer or other mining machinery and drilling in coal bench shall be made in such a way so as to avoid any shale band. If any unavoidable thickness of shale band come into picture, then it may be segregated by help of any excavator to load the shale band and throw them separately, if possible.

(B).Coal Bench In-Charge of Surface Miner face shall ensure that that the face shall be cleaned before cutting by Dozer or other mining machinery and cutting in coal bench shall be made in such a way so as to avoid any shale band. If any   unavoidable thickness of shale band come into picture, then it may be segregated by help of any excavator to load the shale band and throw them separately, if  Possible. No reject coal shall be loaded into any vehicle carrying coal to siding.

2.0   The Blasting Officer shall ensure that blasting shall be made in such a way that

Proper fragmentation of coal will occur. He will also check the depth of the hole made in the bench. If depth is more than the predetermined depth of the bench, he shall use the decking method to avoid the propagation crevices, fissures or cracks in shale band so that an intermingling of shale with coal may be avoided.

3.0Manager shall be responsible for maintaining the declared grade of coal. For this purpose he should deploy sampling personnel to take coal sample of seam/face/ stock at CHP periodically. He shall maintain the analysis results to check the quality variations along with the cross section of the seam. He shall not allow any carboneous /shale materials, or Rejects in case of Surface Miner face to be loaded into any tipper. Moreover, when it comes to his notice about such transportation, he shall immediately stop the vehicle and take necessary action against the defaulters.

4.0.The CHP-In-charge shall supervise the running of CHPs with due proper consideration to quality and size (-100mm). If any obstruction such as big boulders or stone, shale etc during crushing operation is noticed then it shall be ensured that from which face the coal had been carried and information shall be given to Manager and Project Officer for further action. The CHP- Incharge shall also not allow any such tippers to dump the material near CHP stock.           

5.0. Despatch Office shall be held responsible for dispatching accurate quantity and accurate quantity and declared quality of coal not only in Local Sale vehicle but also in siding tippers. He shall personally check the pit stock as well as some representatives’ tippers at random basis to check the quality variation. If any abnormalities are found, then he shall consult with Manager and concerned Coal Face In charge. The rectification report shall be intimated to Project Officer. Moreover, he shall arrange to take coal sample periodically as per his convenience and maintain the record of analysis results. These results may be produced before any consumers, if they require.

6.0. All Shift In-charge shall be held responsible to ensure   loading of quality coal into tippers. They shall obey the instructions of General Shift In-charge, their seniors and any higher authority of MCL and comply the instructions accordingly.

7.0. The Nodal Officer (Siding) shall be held responsible for proper stocking of coal, maintaining the grade and under load/ over load of rakes. If some trips carrying poor quality coal, he shall stop the tipper and inform the Manager about the quality. If some trips have already been unloaded at siding platform then these trips may be clearly demarcated by either red flags or conspicuous branches of bushes/ trees. These materials shall not be loaded into rakes at any cost. 

8.0.All the loading contractors are responsible to track cleaning, empty wagons checking, door closing of boxes and standard height loading as well as proper levelling and rectification work, if found, any under / over loading they shall be give direction to their pay loaders/authorised munshis regarding obey the standing orders siding personnel and maintain discipline for loading of coal with quality assurance.

9.0All Transporting Contractors are responsible to transport assured quality coal. If any extraneous materials such as stone, shale are found in their vehicles. The vehicle will be stopped at siding and returned back to the place where it was loaded. This, the contractor will be responsible.

10.0    The security personnel shall be held responsible to prevent entry of the un-authorised persons / tipper helpers within siding premises, checking the pilferage of coal /mining machineries from siding , patrolling weighbridges frequently and checking the gate pass including stamping. They are also responsible to maintain the “law and order” situation and maintain the discipline within the siding premises.

11.0 The Official personnel are held responsible to proper maintaining of Red register (over/under loading) siding position register, D/note and RR register receiving progressive, Billing register, Remarks register and Attendance register and DC bill. They are responsible to, whatever, works related to run the siding smoothly. They shall also   prepare “Sales Register” and “Coal Despatch and Customer Payment Register” viz. are an essential requirement under ISO: 9001: 2000 cl.8.2.4 and 8.3. They shall  prepare Data Analysis Plan by different analytical tools every month in terms of  plotting line graphs to separately so the trend of penalty payment and grade slippage  as well as trend of sales realization against value of coal despatch by the Project over the  year.

12.0All the quality personnel shall be held responsible to maintain the quality of rakes loaded as well stock stored in siding, and maintain the analysis reports. They shall identify and report non confirming coal under format 9.16 under ISO: 9001:2000 cl 8.3 when grade slippage is noted in more then 40% samples tested in the month and quality deviation due total penalty payment during the month of Indian Railway amounting to 5% or more of the total freight charges due to under loading and /or overloading of wagons.  He shall be responsible for taking samples of each rakes and submit the analysis result in a month to Manager & Project Officer, LOCP. He shall maintain consumer remark register as well as registers required under ISO 9001: 2000 cls.8.2.4 and 8.3. In case of non conforming coal (i.e.when the grade slippage is noted more than 40% sample tested in a month), he shall identify and a report to Project Officer under format 9.16 under ISO 9001: 2000 cl 8.3

13.0This code of Practice shall be implemented with immediate effect.
