Work of In-House Coal Sampling, consists of various jobs related to Collection, Transportation and Preparation of different Coal samples for Coal As received, Coal As fired, Mill Reject and Stock-Yards etc. with other associated work along with the regular cleaning of sampling arenas and equipment associated therewith at STPS, Sarni.

SAMPLING FOR “COAL-AS-RECIVED” FOR COAL RECEIVED BY TRUCKS, BELT AND RAIL MODE: Round the clock collection of increments (as directed and decided by coal sampling staff) from 10 to 20 loaded trucks/Belt/Rail wagon received from various sidings respectively at STPS Sarni. Transporting the same to Godhani sampling shed. The sample will be prepared as per ISI 436 (Part-I) 1964 under supervision of coal sampling staff.

SAMPLING FOR “COAL-AS-FIRED” FROM CONVEYER BELTS, FEEDED TO POWER HOUSES: Every shift collection from Auto Sampler at TP-10 for power house IV & from conveyer 6A,6B for PH-II & III and transporting the collected samples to Goldani sampling shed for preparation. The sample will be prepared as per ISI 436 (Part-I) 1964 and under supervision of coal sampling staff. Note: sampling & their transportation and preparation of separate consolidated sample for the power house in a day will be treated as ONE JOB/ ONE SAMPLE i.e. 365X 2 =730 jobs/samples in a year.

SAMPLING FOR “BULK-DENSITY” FROM SIX DIFFERENT COAL YARDS: Collection of samples for bulk density measurement, approx. 100 Kg. from each stock yard like MCC 4, 4X, 5 NO. yard, 13 No. yard, old stacker yard New stacker yard, transporting the same to Godhani sampling shed. The sample will be prepared as per ISI 436 (Part-I) 1964 under the supervision of coal sampling staff. Note: sampling from one stock yard in a month will be treated as ONE JOB/ONE SAMPLING, so it will be SIX JOB/SIX SAMPLES IN A MONTH i.e. 6 x 12 = 72 jobs/samples in a year.

SAMPLING FOR “COAL-REJECTS” FROM TWO DIFFERENT UNITS OF STPS: Note: sampling from one Reject yard of the Unit in a week will be treated as ONE JOB/ONE SAMPLING, so it will be TWO JOB/TWO SAMPLES IN A WEEK i.e. 2 x 4 x 12 = 96 jobs/samples in a year.

SAMPLING OF COAL FROM “COAL-FEEDERS” OF TWO UNITS, AS AND WHEN REQUIRED: Collection of increment various coal feeder of the units approx. 80 kg, the samples collected from per feeder will be transported to Godhani sampling shed. The sample will be prepared as per ISI 436 (Part-I) 1964 under the supervision of coal sampling staff. The expected frequency per unit is twice in a month i.e. 2 x 2 = 04 sample in a month and 4x 12 = 48 samples in a year. Note: sampling from Feeders of one Unit in a Fortnight will be treated as ONE JOB/ONE SAMPLING, so there will be maximum 02 JOB/02 SAMPLES IN A Fortnight i.e. 2 x 2 x 12 = 48 jobs/samples in a year.

COAL SAMPLING FROM DIFFERENT COAL STOCK YARDS FOR WEIGHTED AVERAGE OF GCV COAL AS RECEIVED POWER HOUSE WISE: Collection of samples approx. 100 Kg. from each stock yard like MCC 4, 4X, 5 NO. yard, 13 No. yard, old stacker yard New stacker yard, transporting the same to Godhani sampling shed. The sample will be prepared as per ISI 436 (Part-I) 1964 under the supervision of coal sampling staff (for weighted average of coal as received of PH- II,III and PH-IV). Note: sampling from one stock yard per day will be treated as ONE JOB/ONE SAMPLING, so it will be FIVE JOB/FIVE SAMPLES PER DAY i.e. 5 x 365 = 1825 jobs/samples in a year.
