RANIGANJ COAL FIELD. 



[Chap. IV. § 4. 



It is about 80 or 100 feet above the top of the last detailed section. 



The coal is said to have been very inferior. The 

 New ditto or Salunchi. . , 



seam now worked at the Chmakuri or Salunchi 



colliery is 600 or 700 feet higher, and none is known to intervene 



between the two. The new or Salunchi seam is altogether 10 feet 



thick,* but only 7 feet of the upper portion is worked. The section of 



the old engine shafts is said to be f : —

The quality is good. The seam has been worked for a distance of 

 at least a mile along the out-crop, to a depth of about 100 or 120 feet. 

 Deeper workings have now been commenced, the coal at a small depth 

 having been nearly exhausted. 



The out-crop of this seam probably stretches for 1 or 2 miles to 

 the East, and may perhaps be found just South of the villages of 



* This I learn from the section in the possession of the Bengal Coal Company, and which 

 is given below. The lower seam, 3 feet 6 inches thick, is also given in the sections of Messrs. 

 Williams and Homfray, but as it is not worked, no complete section of the seam is exposed, 

 and I have never seen it. It appears to be wanting South of the Damuda, at Hirakund. 



f About 50 feet above the Chinakuri seam, a bed of coal, about 1 foot thick, occurs, which 

 is omitted in this section. It is seen in the stream West of the colliery, and was found in 

 sinking for the new engine shafts.
