Underground Hardrock Mines


Underground Hardrock Mines

Ground stability is integral in keeping underground hard rock mines productive and profitable.

Weak strata can have expensive consequences for hard rock mining companies. It can cause equipment to malfunction, which can reduce productivity or even bring operations to a standstill. It can cause also hazardous movement of mine walls and floors and, in extreme cases, mine collapse.

Underground voids and cracks can cause water ingress, which damages site infrastructure and can pose safety risks.  

Mainmark is an expert in ground engineering and we specialise in solving geotechnical problems in underground hard rock mines.

Our proven solutions deliver engineered outcomes that strengthen and consolidate ground, and our highly experienced team knows how to meet the advanced requirements of modern underground mining methods.

We can:

  • strengthen, stabilise, and consolidate weak rock strata using our Teretek engineered resin solution or specialised urea silicate resin injection technologies
  • fill underground voids and seal unused shafts using resin injection technologies or our proprietary lightweight cementitious fill solution, Terefil
  • rehabilitate damaged oil, gas, water, and chemical pipelines using Primus Line
