What Wilson Mining Services Pty. Limited does

Wilson Mining Services Pty. Limited is an Australian specialist mining services contractor founded in 1990 and headquartered in Gateshead, NSW, with a secondary office in Mackay, QLD. The company delivers cavity filling, strata consolidation, secondary support installation, and ventilation control device services to underground coal mining operators across the Hunter Valley (NSW) and Bowen Basin (QLD), with additional work in New Zealand. It operates as a wholly-owned subsidiary of Mastermyne Group Limited following an August 2019 acquisition, deploying approximately 85 specialized crew members on either routine site contracts or emergency campaign deployments.

The company's core offering is built on proprietary chemical injection technology, most notably the ROCSIL FOAM phenolic resin family (LS1 cavity fill and HD20 high-strength variants) which expands up to 35x original volume and hardens in approximately five minutes. Complementary product lines include Marithan polyurethane (PUR) systems for strata consolidation, Fenoflex phenolic resin for reduced-health-risk injection, Marisil E organomineral silicate resin, and the Micon Explosion Resistant Seal (ERS) ventilation control system rated to 50 PSI overpressure. Wilson Mining is the exclusive Australian supplier of Weber Mining (France) PUR and silicate technology and of Micon Group (US) explosion-resistant seals, and operates supporting equipment including Clark Series 5000 crawler drill rigs and a 1000L bulk chemical handling system that replaces traditional 20L drum logistics. Multiple product lines hold NSW DPIE polymeric process licences, and the company maintains ISO 9001, ISO 14001, and ISO 45001 certifications.

Wilson Mining generates revenue by providing specialized labor and proprietary chemical products directly to mining operators under multi-year commercial contracts and emergency mobilization engagements. Go-to-market is enterprise field sales with crews deployed on customer mine sites rather than product resale, and the customer base includes major Australian underground coal operators such as BMA (BHP Mitsubishi Alliance), South32, Vale, Bulga Underground Operations, Austar Coal Mine, Cornwall Coal, North Goonyella, and Solid Energy. Pricing is quote-based and not publicly disclosed. Following the 2019 acquisition, Wilson Mining operates as a Mastermyne Group business and continues to expand its product line, with recent launches including Marisil E (2020), the FRAS Gas Drainage Stand Pipe/Plug range (2025), and ongoing development of Stratanet polypropylene roof mesh.

Core offering

Wilson Mining Services is a specialized underground coal mining services contractor that develops, supplies, and applies proprietary chemical injection products (cavity fill, strata consolidation, ventilation control) for mine ground support. The company deploys specialized work crews directly to mine sites in NSW and QLD to deliver cavity filling, strata consolidation, secondary support installation, and sealing of underground heating and fire events, using its own ROCSIL FOAM, Marithan PUR, Fenoflex, Marisil E, and Micon ERS product lines alongside Clark drill rigs and bulk chemical handling systems.

Product overview

Wilson Mining Services is a specialized underground coal mining services company offering a portfolio of chemical products for cavity fill, strata consolidation, and ventilation control. The core product lines include ROCSIL FOAM (phenolic resin cavity fill in LS1 and HD20 variants), Marithan Polyurethane (PUR) and Fenoflex (phenolic resin) for strata stabilization, and Marisil E (silicate resin). The company also provides Micon Explosion Resistant Seals for ventilation and water bulkhead applications, plus supporting equipment including Clark drill rigs and bulk chemical handling systems.

Products and services

• ROCSIL FOAM LS1 Industry-leading two-component phenolic resin cavity fill product used for cavity filling, air and gas sealing, fire fighting, and stabilization of highly fractured strata in underground coal mines. Expands up to 35 times original volume, hardens in approximately 5 minutes, and is applied at up to 50 m3/hour. LOBA approved and applied over 1300 times in Australia and NZ.
• ROCSIL HD20 High-strength two-component phenolic resin product developed specifically for mine plug seals rated to 50 PSI overpressure loading for blast event sealing, air and gas sealing, and firewall erection at safe distances in underground coal mines. Expands 20x original volume.
• Fenoflex Flexible two-component phenolic resin strata injection system for strata consolidation providing major improvements in safety and productivity versus polyurethane injection. Features maximum exotherm of 60°C regardless of volume, 600kg hole limit (3x polyurethane), fire resistant, antistatic, and contains no isocyanates.
• Marithan Polyurethane (PUR) Flexible two-component polyurethane strata injection resin systems (N and S variants) particularly well suited for strata consolidation of fractured ground in underground coal mines. System N stabilizes and confines fractured strata; System S handles water-bearing strata and stops water migration with low viscosity for penetration into fine cracks.
• Marisil E Two-component elastic organomineral resin strata consolidation system comprising silicate and modified polyisocyanate. Sets fast, penetrates cracks and fissures, creates an elastic bond capable of retaining integrity after rock movement in both dry and wet conditions. Non-foaming with very short setting time.
• Micon Explosion Resistant Seal (ERS) Benchmark ventilation and water bulkhead seal for the Australian mining industry. Polymer core with expansion properties, explosion tested design rated for 20, 50, and 120 psi overpressure. Incorporates composite structure with special high-tech polymer material and concrete block, and tolerates up to 10% roadway convergence without diminishing pressure rating.
• Micon HB (High Bond) Seal New ventilation control device development featuring PUR-glued masonry blocks with thinner PUR/gravel core thickness compared to standard Micon ERS. Reduces materials requirements and cost while retaining convergence and water resistance features.
• Gas Drainage Stand Pipe/Plug FRAS-rated gas drainage piping range including copper piping, hose over plugs, groutable plugs, with or without water traps. Standpipe can be fitted and sealed in the same operation using expansion Rocsil Foam that expands 35 times its original liquid volume. FRAS and licensed for underground coal mining use.
• Clark Series 5000 Mobile Drill Rigs Compressed air powered, crawler tracked drill rigs for secondary support and specialized drilling in underground coal mines. Capable of vertical, horizontal or angled drilling with 360° mast rotation.
• Bulk Chemical Handling System Bulk chemical handling system developed for step-change improvement in handling chemicals in underground coal mines. Chemicals supplied in 1000L intermediate bulk containers (IBCs) instead of 20L drums, with redesigned bulk handler pods transporting up to 3 IBCs (37.5% more chemical per bulk handler). Closed system reduces chemical exposure and eliminates drum handling.
• Cavity Filling Service On-site cavity filling service deploying specialized work crews to underground coal mines to fill roof cavities, seal air and gas pathways, fight fires, and stabilize highly fractured strata using ROCSIL FOAM LS1 and HD20 chemical systems.
• Strata Consolidation Service On-site strata consolidation service deploying specialized work crews to inject Marithan PUR, Fenoflex, or Marisil E resin systems into fractured strata to stabilize ground and seal water-bearing zones in underground coal mines.
• Secondary Support Installation Service On-site secondary support installation service using Clark Series 5000 mobile drill rigs for vertical, horizontal or angled drilling to deliver specialized bolting and support in underground coal mines, compliant with NSW Mines Department guidelines MDG1, MDG22, MDG35 and MDG41.
• Sealing Underground Heating and Fires Service Emergency on-site service deploying specialized work crews to seal underground heating events and mine fires in underground coal mines, using ROCSIL foam for temporary seals and Micon ERS for permanent explosion-resistant barriers.
