105 READER: REPORT ON THE RAMPUR COAL-FIELD. 



an experimental shaft was sunk on to it and several tons of 

 coal extracted. I have not seen any report on the tests made 

 with the coal extracted, but from the appearance of the coal 

 stacked near the shaft, I would have judged the seam as worth- 

 less: subsequent experiments confirmed this. The original depth 

 of the borehole was only 60 feet, it having been thought unlikely that 

 there was more coal at a greater depth. As explained previously, 

 Mr. Griesbach, Director of the Geological Survey, was not satisfied 

 that there was no more coal at a greater depth, and Government 

 acting on his advice sanctioned the deepening of the Kodopali 

 borehole until the Talchir rocks were struck. This borehole was 

 stopped at a depth of 485 feet, before reaching the Talchirs. 



The coal proved by the borehole, at a depth of 15 feet, and in 

 the shaft, was described as evidently the same as the Durlipali 

 and Eeb river seams. The Kodopali Diamond Drill boring 

 appears to have been put down on this assumption and is therefore 

 supposed to have proved nearly 500 feet of measures below the 

 Durlipali seam. 



Now beyond a similarity in the appearance of the seams and a 



Kodopali No. 4 , Diamond very rough alignment of the Kodopali boring 



Dull boring. w ; th the strike of the Durlipali seam, there 



are no grounds that I know of for correlating the Durlipali and 

 Kodopali exposures, and when it is remembered that the distance 

 from the Durlipali outcrop to the Kodopali boring is three miles, 

 such an assumption can be, to say the least, only of little worth. 

 There can be no doubt that the ground proved by the Diamond 

 boring is near the base of what I have made my third zone, but at 

 present there are no datd sufficiently well substantiated to fix the 

 exact horizon of the top of the hole. My own opinion is that it is 

 some 200 feet or more above the top of the Durlipali seam. Be that 

 as it may, the borehole verifies the Director's opinion that coal does 

 exist below the seam proved in the shaft, and generally gives 

 results sufficiently encouraging to justify further exploration of the 

 lower Barakars.
