About Us

ZOK II" Sp. z o.o. is a leading company in the construction and modernization of methane drainage stations, with prominent projects at 1 Maja, Marcel, Staszic, Wesoła, and Brzeszcze. Since our inception, we have been dedicated to geological exploration, resulting in the extraction of tens of kilometers of drill core. Utilizing drilling rigs from reputable manufacturers like OMAG and Atlas Copco, we achieve over 95% core recovery using the latest technologies.

ZOK II is a market leader in directional drilling in Poland. This technique allows us to change the trajectory of the drilled borehole, providing functional positioning and course. Directional drilling serves as a cost-effective and efficient alternative to traditional drainage roadways. It can also be utilized for:

• Draining water reservoirs.
• Creating piped holes to shortcut main pipelines.
• Inerting fire fields.
• Conducting directed research and core test boreholes for precise geological analysis.

• Drilling Rigs: Over 40 different rigs at our disposal.
• Methane Borehole Efficiency: Capable of drilling up to 12,000 meters per month.
• Technological and Core Borehole Efficiency: Capable of drilling up to 600 meters per month.
• Methane Drainage Maintenance: Ongoing maintenance services for five different mines..

ZOK II offers comprehensive services related to methane drainage system design and implementation, including:

• Designing Methane Drainage Systems: Boreholes, pipeline installation, and methane drainage stations both on the surface and underground.
• Underground Drilling: Drainage holes for the demethanation of longwalls and roadways.
• Core Drilling: Achieving 95% efficiency, using technological and large-diameter holes with raise boring technology and RVDS accuracy.
• Pipeline Construction and Disassembly: Methane drainage pipelines.
• Gas Intake Regulation: Using drainage holes and pipelines.
• Operation of Methane Drainage Stations: Both underground and surface stations.

Our services are available 24/7, ensuring continuous operation and maintenance.

We employ high-class specialists who utilize advanced technologies to ensure safe coal extraction. Our efforts eliminate risks such as methane accumulation, inflammation, and explosions. As of September 30, 2023, our team included 292 employees, the majority of whom possess underground qualifications. Among them, 67 specialists with supervisory and management qualifications have extensive experience in drilling and methane extraction from underground excavations.
