MINING TAMPING SUPPLIER FREE STATE
Specialist tamping and stemming supply for the Free State Goldfields and Free State coal-mining operations.
OGM Supplies manufactures and supplies bulk and capsule tamping products used in blast-hole charging across South Africa’s underground mining operations. In the Free State, our tamping and stemming products support two very different mining environments: the deep-level narrow-reef gold mines of the Free State Goldfields, and the underground coal operations that feed Sasol’s Free State plants. Both depend on consistent, SANS 120:2009-compliant tamping to help confine explosive energy safely inside the blast hole.
TAMPING SUPPLY FOR THE FREE STATE GOLDFIELDS
The Free State Goldfields, centred on Welkom and Virginia, has been in production since the 1940s and remains one of South Africa’s most significant narrow-reef gold mining regions. Harmony Gold operates Tshepong and Phakisa near Odendaalsrus, Target near Allanridge, Masimong at Riebeeckstad, Joel near Theunissen, and Bambanani at Welkom. Sibanye-Stillwater’s Beatrix operation, between Welkom and Virginia, has a life of mine extended to 2031.
Deep, narrow-reef stoping places specific demands on tamping and stemming products: shot holes are often smaller in diameter, working faces are confined, and blasting crews need dimensionally consistent products that seat correctly every time. OGM Supplies manufactures to a consistent specification, so blasting teams across the Goldfields get the same product performance shift after shift.
SUPPORTING FREE STATE COAL OPERATIONS
North of the Goldfields, in the Fezile Dabi district around Sasolburg, Sasol Mining’s Sigma Mooikraal Colliery continues to supply coal to Sasol’s Free State utility plants. Underground coal mining carries its own blasting profile, different from narrow-reef gold, and stemming products need to suit the hole geometry and ground conditions typical of coal seam extraction. OGM Supplies supplies both bulk and capsule tamping formats, so procurement and blasting teams can match the product to the application.

FREQUENTLY ASKED QUESTIONS
Do you deliver tamping and stemming products to mines in the Free State Goldfields?
Yes. OGM Supplies delivers regularly to mines and blasting contractors around Welkom, Virginia, Odendaalsrus, Allanridge, Theunissen, and Riebeeckstad, as well as to Sasolburg and the northern Free State coal-mining area.
Do tamping requirements differ between the Free State’s narrow-reef gold mines and its coal operations?
Yes. Narrow-reef gold mining around Welkom and Virginia typically needs smaller, dimensionally consistent tamping products suited to confined stoping faces, while coal mining around Sasolburg works larger blast hole diameters. OGM Supplies manufactures both bulk and capsule formats to suit either application.
What is the typical lead time for orders delivered into the Free State Goldfields versus Sasolburg?
Lead times depend on order volume and product specification. Sasolburg, directly across the Vaal River from our Vereeniging base, is typically the faster turnaround, while Welkom and the wider Goldfields add extra transit time. Contact us with your required delivery date and we will confirm turnaround for your order.
Can tamping products be custom-sized for narrow-reef stoping faces?
Yes. OGM Supplies offers custom blends and sizing to match the smaller shot hole diameters and confined working faces typical of narrow-reef gold mining in the Free State Goldfields.
Do you supply both bulk and capsule tamping formats?
Yes. We manufacture and supply both bulk and capsule tamping products, so mines can select the format that best matches their blasting application.
What accreditations does OGM Supplies hold?
OGM Supplies holds BEE and MASC accreditation. Full accreditation documentation is available on request or via our Accreditations page.
Do you supply mines directly, or only through blasting contractors?
Both. We supply mines directly as well as accredited blasting contractors operating across the Free State.
