We utilize the open-pit mining method, which facilitates access and extraction of marble blocks from our marble mine, reducing the risk of accidents caused by collapsed mine roofs, mine floods and the leakage of harmful gases. Compared to underground mining, our open-pit mining operations generally do not involve the use of explosive materials or hazardous chemicals, thereby significantly reducing safety and environmental pollution concerns.
We are committed to following environmentally responsible practices and have adopted measures to minimize the impact and risk of our operations on the environment.
We utilize water with drilling, cutting and sawing activities, water sprays at material transfer points, and water trucks to spray the roads during dry periods to reduce dust from mining operations.
The mine site has also been designed to recycle used water for production activities and dust suppression. Production water and rain falling on the mine area are drained to a central sump where the water is settled and cleared of sediment before being recycled back into ongoing production activity.No toxic or hazardous substances are contained in the drainage water.
We have a limited amount of tailings because our Zhangjiaba Mine is highly utilizable and, as a result, we do not incur additional handling costs.
Methods of noise control include use of silencers, noise and vibration dampening and absorbing materials, isolation and enclosure of noisy equipment, and regular equipment maintenance. We also undertake regular noise, water and air quality monitoring as well as an ongoing reclamation and re-planting program for disturbed areas.
We are confident in our ability to further enhance our safety and environmental protection capabilities, meet the increasingly strict safety and environmental protection standards imposed by the PRC Government and reduce any exposure to potential incremental costs or contingent liabilities relating to safety and environmental protection.
