The developed Lakhra coalmine has total estimated reserves of 1,328m tonnes of lignite and sub-bituminous coal, of which 244m tonnes are measured and mineable.
Two representative coal samples from Lakhra coalmines labeled Lakhra-3 (L3) and Lakhra-6B (L6B) were pyrolyzed in their raw state and after treatment with tetralin. Initial experiments were carried out at 700 °C with 2 milligrams of 80 mesh size samples.
The Lakhra coal field lies 141km from Karachi in the North West direction, 35km north west of Hyderabad and 15km west from Jamshoro (in between latitudes 25 o30 / and 25 o45 / N and longitudes 68 o0/ 68 o15 / E) Coal field spreads over 1309 sq.km on both sides of Jamshoro-Dadu metalled road Coal seams are at shallower depth (50 to 450 m) in the ...
Lakhra coal is classified as lignite with medium ash, high sulphur, having average calorific value of 6057 Btu/lb, 3365 Kcal/kg. LPGCL. Lakhra Coal Development Company Limited (LCDCL) is operating under the administrative control of Ministry of Petroleum & Natural Resources, GoP. …
The Lakhra coal field is about 20 miles northwest of the ancient city of Hyderabad on the west side of the Indus River Valley in the southern part of Pakistan. The Lailian coal bed in the lower part of the Ranikot Formation under- lies an area of at least 64 sq mi on the Lakhra anticline, averages 3.6 feet thick, but is locally as much as 8.2 feet thick.
It is inferred that the Lakhra and Sonda coal fields, and perhaps even discrete coal zones, or beds, are continuous with one another, but confirmation of this requires additional drilling in the southern part of the Lakhra area. The calculated rank of the coal in both fields ranges from lignite A to
Lignite mud system is applicable preferentially in such conditions because of its low cost, inhibitive properties and tolerance to high mud weights. A study has been undertaken to evaluate the characteristic properties of lignite from Lakhra Coal mines, district Jamshoro, Sindh Province as drilling mud additive.
The Lakhra coal ranges from lignite A to sub-bituminous C, with high volatile matter (26.3 to 42.5%), high sulphur (1.8 to 6.5%) and high ash (7.4 to 25%). The gross calorific value ranges between 2,570 to 4,260 k.cal/kg of coal. Quality varies widely even within a specific seam. Lakhra coal demonstrates high moisture, high sulphur and low ...
Prior to the discovery of Thar coal reservoirs, Lakhra was the largest coal field of Brown Lignite coal with high ash and sulfur contents, i.e. 30% and 7%, respectively. The power generation ...
Lakhra coal is lignite with a calorific value ranging from 5503-9158 Btu/lb. A feasibility study conducted in 1996 found Lakhra lignite suitable for power generation, however, high content of moisture, ash, and sulfur has made it unsuitable for direct combustion and hence its …

Lakhra coal cluster is famous for lignite type coal extracted from mines. According to the report published by Sindh Coal Authority and as per discussions with industry players, the chemical composition of the coal is defined below: TABLE 4: COAL OF LAKHRA- CHEMICAL ANALYSIS 7 Description Content Moisture (AR) 28.9% Ash (AR) 18%
Abbas S G, Atiq M. Coal deposits of Sindh, in proceeding of Geological Survey of Pakistan–Sindh coal authority joint workshop on coal, granite, China clay and other resources of Thar, Karachi, May, 31, 2005. (Web consulted on 2007, 9–6).
In addition to this, there are lignite coal reserves in Lakhra, Sonda, Indus East and other coalfields of Sindh. The Lakhra coal field is thoroughly investigated and developed. Several public and private mining companies are mining coal from Lakhra. It has been confirmed that Lakhra coal is …
