The non-mechanical properties of rocks, such as thermal conductivity, electrical resistivity, and acoustic velocity, can play a significant role in exploration drilling. These properties affect how rocks interact with external forces and help determine the best drilling techniques and equipment for specific conditions.

1. Thermal Conductivity

Thermal conductivity refers to the ability of a rock to conduct heat. This property is important when drilling in hot environments or when using drilling fluids that require temperature management. Rocks with high thermal conductivity, such as granite, require equipment capable of handling high-temperature conditions, such as the Portable full-hydraulic core drilling rig, which is built to withstand heat and provide consistent performance.

2. Electrical Resistivity

Electrical resistivity is a measure of a rock’s ability to resist the flow of electrical current. This property is particularly useful in mineral exploration, as it can help identify areas rich in certain minerals. Understanding the resistivity of rocks helps in selecting drilling equipment that minimizes interference and optimizes core sampling, such as the core drilling and sampling rig.

3. Acoustic Velocity

Acoustic velocity refers to the speed at which sound waves travel through a rock. It can be used to determine the porosity and density of rocks, providing insights into how easily they can be penetrated. Acoustic velocity is particularly relevant when working with porous or fractured rocks. For these conditions, the Portable bore sampling rig is ideal as it allows for accurate measurements and efficient core sampling.

In conclusion, the non-mechanical properties of rocks, such as thermal conductivity, electrical resistivity, and acoustic velocity, provide essential information that helps in making informed decisions about exploration drilling methods and equipment.
