Geology of the Maheshpur Colliery has been established by surface and sub surface data from Geological Report of 1) Kharkharee Block, 2) Dharmaband Block & 3) Opencast Block-III. Maheshpur Colliery is located in the west central part of Jharia Coalfield. The area is occupied by strata of Barakar formations containing Coking and Non-coking coal seams. The area is mostly under soil cover and good outcrops are rare.Strike & DipIn general, the strike of the formation is NE-SW and dip varies from 3° to 26° due south.FaultsSix faults have been interpreted in this area. The throw of the fault varies from 10m to 120m. However, faults having throw less than 5m could not be ruled out in the area.Igneous Intrusion / Pyrolitization The coal seams of the area have been intruded by two dolerite dykes:Maheshpur Dyke- 40m thick dyke located in the western part of the area dipping 80° / SE. Tundu Dyke- 30m thick dyke located in the central part of the colliery.Geology of the Block IV Colliery has been established by surface and sub surface data from Geological reports of (i) Opencast Block-IV (Seams VIIIC to I/II) & (ii) Opencast Block-IV. Kooridih Colliery is located in the western part of Jharia Coalfield. The area is occupied by strata of Barakar formations containing Coking and Non-coking coal seams. The coal bearing rocks of Barakar formation of Lower Permian age occur in the Colliery area under a thin cover of soil and/alluvium (5 to 10m).Strike & Dip In general the strike of the formation is E-W and the dip varies from 5° to 14° due south.FaultsTwo major faults are encountered in this area. However, faults having throw less than 5m could not be ruled out in the area.Jogidih Colliery is located in the western part of Jharia Coalfield. The area is occupied by strata of Barakar formations containing Coking and Non-coking coal seams. The coal bearing rocks of Barakar formation of Lower Permian age occur in the Colliery area under a thin cover of soil and/alluvium (5 to 10m).Strike & DipIn general the strike of the formation is E-W and swerves to N-S in the southcentral part. Dip varies from 2° to 12° due south. FaultsOne major fault is encountered in this area. However, faults having throw less than 5m could not be ruled out in the area.Igneous Intrusion The coal seams of the area have been intruded by three dolerite dykes: 1. Maheshpur Dyke- 40m thick dyke ocated in the western part of the area dipping 80° / SE. 2. Tundu Dyke- 30m thick dyke located in the S-W corner and joins the Maheshpur Dyke in the colliery.3. Jogidih Dyke- 20m thick dyke, runs almost N-S and forms the eastern boundary.Akashkinaree Colliery is located in the western part of Jharia Coalfield. The area is occupied by strata of Barakar formations containing Coking and Non-coking coal seams. The coal bearing rocks of Barakar formation of Lower Permian age occur in the Colliery area under a thin cover of soil and/alluvium (5 to 10m). A dyke trending E-W is present in this area. By and large the coal seams are free from pyrolitisation.Strike & DipIn general the strike of the formation is E-W and the dip varies from 7° to 16° due south. FaultsNo fault is encountered in this area. However, faults having throw less than 5m could not be ruled out in the area.
