Dolomite Investigations

Geotechnical Assessment

Dolomite drilling requires a thorough geotechnical assessment to evaluate the stability and characteristics of the dolomite rock. Factors such as rock density, strength, porosity, and permeability need to be considered.

Location and Depth

The location and depth of drilling play a crucial role in dolomite investigation. Different areas may have varying dolomite formations, and the depth of drilling will determine the extent of exploration required.

Water Table

The proximity of the water table to the drilling site is important, as dolomite can be susceptible to dissolution and collapse when in contact with water. The water table level should be assessed to prevent potential hazards.

Environmental Impact

Drilling in dolomite areas may have environmental implications. It is important to assess potential impacts on groundwater quality, land stability, and the surrounding ecosystem.

Safety Measures

Proper safety measures should be implemented during dolomite drilling to ensure the well-being of workers and prevent accidents. This includes using appropriate drilling techniques, monitoring ground conditions, and conducting regular safety inspections.

South African Legislation about Dolomite Drilling:

In South Africa, dolomite drilling is regulated under various legislation and guidelines to ensure safe practices and prevent hazards associated with dolomite formations. Here are some relevant regulations:

The National Environmental Management Act

This legislation establishes guidelines for environmental management and impact assessments, which apply to dolomite drilling projects. It requires environmental authorisations to be obtained before conducting drilling activities.

The Mineral and Petroleum Resources Development Act

This act governs the exploration and exploitation of mineral resources in South Africa, including dolomite. Companies require mining rights or permits to engage in dolomite drilling for commercial purposes.

The Occupational Health and Safety Act

The OHS Act specifies health and safety regulations for workplaces, including drilling operations. It ensures that adequate safety measures are in place to protect workers during dolomite drilling activities.


In South Africa, building regulations take dolomite stability into account. They provide guidelines for construction and structural design in dolomite areas to ensure the safety of buildings and prevent potential collapses.
