In Complex Geology
From soft soil layers to hard rock formations,
Balancing efficiency and cost-effectiveness
TOP 01: Soft Soil Formations
Soft soil layers, such as silt and clay, are characterized by high water content and low
strength. In these types of formations, rotary drilling picks must possess excellent
cutting performance to rapidly break up and excavate the soil. Generally speaking,
picks designed for soft soil formations have sharper tip shapes, allowing them to slice
easily into the soil layers and minimize cutting resistance.
TOP 02: Hard Rock Formations
In stark contrast to soft soil layers, hard rock formations—such as granite and
basalt—have extremely high hardness, posing severe tests to the performance of
rotary drilling picks. In hard rock drilling, the picks must not only withstand enormous
impact forces but also exhibit outstanding wear resistance and chipping resistance.
Value Propositions of Mailinmaite Hard Rock Picks:
• Design: Mailinmaite hard rock picks utilize a conical tip that concentrates force,
making it easier to cut into hard rock. The body is manufactured using an integral
forging process, increasing impact resistance by over 40% compared to standard
picks. Furthermore, the pick shape is more robust, and the tip angle is
meticulously engineered to enhance rock-crushing capability.
• Material: Premium virgin tungsten carbide is used, delivering exceptional
hardness and wear resistance to effectively withstand rock abrasion.
TOP 03: Complex & Mixed Formations
In real-world engineering, it is far more common to encounter complex mixed
formations, where soft soil, hard rock, and other strata with varying properties
alternate frequently. Under these circumstances, rotary drilling picks require much
stronger adaptability. A wear-resistant coating wards off abrasion from fine sand,
while carbide buttons absorb the impact of gravel, working in tandem to protect the
tool.
