A coal seam affected by a mica-lamprophyre dyke is studied. Samples of strongly affected, partially affected and unaffected portions of the coal, at the actual contact of the dyke with the seam and at increasing distances from this point respectively are subjected to proximate chemical analysis and petrological studies including reflectance measurements by Seyler's method. Electrical conductivity of these samples is also measured. It is concluded that the coal affected by the igneous intrusive undergoes a progressive increase in rank and also suffers a natural process of carbonisation with gradual development of the characters of a coke, as it approaches the contact with the igneous intrusive.

Abstract


A coal seam affected by a mica-lamprophyre dyke is studied. Samples of strongly affected, partially affected and unaffected portions of the coal, at the actual contact of the dyke with the seam and at increasing distances from this point respectively are subjected to proximate chemical analysis and petrological studies including reflectance measurements by Seyler's method. Electrical conductivity of these samples is also measured. It is concluded that the coal affected by the igneous intrusive undergoes a progressive increase in rank and also suffers a natural process of carbonisation with gradual development of the characters of a coke, as it approaches the contact with the igneous intrusive.
