SnapshotBastacolla Area is amalgamation of mines:
1) Amalgamated East Bhuggatdih Simlabahal Colliery now is not operational.
2) Bastacolla Colliery OC+UG. Bastacolla OCP-I Hired HEMM Patch is operational.
3) Bera Colliery now is not operational.
4) Dobari Colliery now is not operational.
5) Ghanoodih Colliery now is not operational.
6) Kuya Colliery OC+UG. Kuya OCP Departmental Patch is operational.
7) Rajapur/S-Jharia OCP. S-Jharia Hired HEMM Patch is operational.

Coal is producing departmentally and/or by outsourcing (i.e Hired HEMM. Operations of overburden removal and coal extraction are being carried out by the coal companies by hiring Heavy Earth Moving Machinery (HEMM) on wet leasing).

Summary:

Geology of Rajapur OCP/ SJ Colliery
Rajapur OCP/ SJ Colliery is located in the eastern part of Jharia Coalfield in Dhanbad district of Jharkhand.

i. Seam IX/X depth range varies from incrop to 75m and its thickness varies from 11.4 to 15.25m. The seam has been worked in most part of the Rajapur mine by both UG (pre-nationalization) and opencast method. The workings developed on B&P method, have been mostly exhausted by caving and small area SOP (standing on pillars)/on stooks due to low cover and hence not proposed for Highwall mining.

ii. Seam VIII C underlies seam IX/X with a parting varying from 2.0 to 11.00 m and its thickness varies from 0.16 to 1.03. The seam has been worked in most part of the Rajapur mine by opencast method and hence not proposed for Highwall mining. Fire is reported in the seam on the south west side of the mine.

iii. Seam VIII B underlies seam VIII C at a parting varying from 4.0 to 9.0 m and its thickness varies from 0.52 to 2.45m. The seam has been worked in most part of the Rajapur mine by both UG (pre-nationalization) and opencast method in northern part of the mine area. The workings developed on B&P method, have been mostly exhausted by caving and small area SOP (standing on pillars)/on stooks and hence not proposed for Highwall mining. Fire is reported in the seam on the south west side of the mine.

iv. Seam VIII A occurs below VIII B seam at a parting of 1 to 21 m and its thickness varies from 0.2 to 4.2m. The seam has been worked in most part of the Rajapur mine by both UG (pre-nationalization) and opencast method. The workings developed on B&P method, have been mostly exhausted by caving and small area SOP (standing on pillars)/on stooks and hence not proposed for Highwall mining. Fire is reported in the seam on the south west side of the mine.

v. Seam V/VI/VII/VIII underlies seam VIII A with a parting varying from 2 to 6 m and its thickness varies from 12.1 to 18.4m.The seam partly incrops in the area. The seam has been worked in most part of the Rajapur mine by both UG (prenationalization) and opencast method. The workings developed on B&P method, have been mostly exhausted by caving and small area SOP/on stooks and hence not proposed for Highwall mining. Fire is reported in the seam on the south west side of the mine.

vi. Seam IV Top underlies combined seam (V/VI/VII/VIII) with a parting varying from 24m to 40m and its thickness varies from 0.12 to 3.59m. This seam is virgin and hence proposed for Highwall mining.

vii. Seam IV Bottom underlies IV Top seam with a parting varying from 17m to 32m and its thickness varies from 0.2 to 2.42m. This seam is virgin and hence proposed for Highwall mining.

viii. Seam III Top underlies IV Bottom seam with a parting varying from 6m to 13m and its thickness varies from 2.51 to 6.99m. This seam is developed by underground method (pre-nationalization) in small patch in the northern part of the mine area. However, the seam is virgin in the area proposed for Highwall mining.

ix. Seam III Bottom underlies III Top seam with a parting varying from 9m to 18m and its thickness varies from 5.97 to 9.65m. This seam is developed by underground method (pre-nationalization) in small patch in the northern part of the mine area. However, the seam is virgin in the area proposed for Highwall mining.

x. Seam II Bottom underlies III Bottom seam with a parting varying from 16m to 25m and its thickness varies from 1.65 to 7.15m. This seam is virgin and hence proposed for Highwall mining.

xi. Seam I Top underlies II Bottom seam with a parting varying from 17m to 25m and its thickness varies from 1.25 to 4.46m. This seam is virgin and hence proposed for Highwall mining.

xii. Seam I Bottom underlies I Top seam with a parting varying from 1m to 4m and its thickness varies from 1.24 to 3.04m. This seam is virgin and hence proposed for Highwall mining.

Dip and Strike
The general strike of the formation is NNW-SSE and the dip of the strata generally varies from 5° to 10° towards SW. However, the average gradient of seam within the proposed zone of highwall mining is 1 in 10.

Faults
The proposed zone of work is not free from faults. There are fault F2 & F3 passing through the designated area proposed for Highwall mining. However, the faults have not been encountered till now while mining.

Crushers and Mills

Milling equipment has not been reported.

Summary:

The coal from mines has been crushed in Feeder Breaker. After crushing the coal to (-) 100 mm coal is transported to different sidings.

Processing

Summary:

Coal production of the Kuya mine is linked to different power houses (Power plants of DVC and other companies) and washeries (Bhojudih washery & Dugda washery) through CK (West), BNR siding and Burragarh siding and rest quantity is transported through road to MPL, RTPS and E- Auction etc. The present lead for coal transportation from face to surface is 1 to 2 km. C. K. West Siding is 3 to 4 km and BNR Siding is about 10 km from the coal dump. Feeder breaker exists in KOCP and 3 Nos. of feeder breaker in C. K. West Siding.
