1. Introduction. According to the latest report by the Department of Minerals and Energy, the Highveld and Witbank coalfields account for approximately 66% of the remaining coal reserves in South ically, the no. 2 Seam in the Witbank Coalfield was the main target for exploitation, but its reserves have declined significantly over the last 2 decades, leading to the no. 4 Seam Cited by: The investigations were based on 14 channel samples covering a 40 × 20 km2 area in the Witbank results indicate that the coals in the No. 2 seam were formed at the stage of major. Abstract. Petrographical and palynological coal-quality investigations relating to variations in one of the best-known and well-researched coalfields in Africa, the Witbank coalfield, and one of the most commercially important seams within this coalfield, the No. 2 seam Cited by: Coal from the No. 2 seam was collected from a single area of elevated basement (pre-Karoo strata) topography (interpreted from unpublished mine plans) within the Ogies region in the Witbank coalfield of the Karoo Basin, South Africa. At this location within the sample mine, the exact location of which cannot be given due to commercial constraints, the roof of the coal was exposed and accessible; none .
Abstract A suite of techniques, including coal petrology, micropalynology, mesofossil analysis, and macroscopic appearance has been used to examine the Early Permian, South African, Witbank Basin. The no. 4 Seam in the Witbank Coalfield is no exception, and it can be described as containing higher inertinite content and minerals compared to the no. 2 Seam in the same Coalfield.

[SCIENCE] To tackle the problem, conservationists have begun using a slew of new gadgets to protect the archipelago’s rare and threatened wildlife.
Reviews at 10 year intervals appear to be constants in the proposed method are valid only for the Witbank No. 1, 2 and 4 seams and the Highveld No. 2 and 4 uctionIt is well known that over time, coal pillars are prone to scaling, and thus are progressively reduced in size and consequently subjected to increased load and. 2. Leraatsfontein becomes Witbank in Actual systematic mining at Witbank only started in when Samuel Stanford,together with the Neumann Group,established the company Witbank Colliery Limited, and sank the first shaft on the farm Witbank. Earlier the farm was generally known as Swartbosch although the official name was Leraatsfontein. The No. 4 Seam Sequence (Fig. 9) comprises the succession incorporating the immediate roof of the No. 2 Seam to the top of the No. 4 Seam, and equates to the Coalville GSS of Le Blanc Smith. opencast mine at Ogies, Mpumalanga. The mine is part of the South African Witbank Coalfield and accesses the No. 2 and 4 Seams with some 5 Seam material.
