Our Columbia customer got a coal mining project and needed an environmentally friendly solution to accommodate the large amount of coal extracted from the mining site. The main site is approximately 454,500 square feet (42,224 square meters) designed to prevent toxic chemicals from coal and by-products from penetrating into the soil.
The project’s estimated service life is ten years, and the unique location of the mine means that the installation site will be exposed to complex environmental conditions. In northern Columbia, the region’s summer months are as high as 95°F (35°C) and winter months are below -60°F (-51°C). In addition, during heavy snow, the site may experience snow loads of up to 120 inches (300 cm). These are all difficult for construction.
The BPM team designed a detailed construction plan. First, the roadbed was smooth, and a 450 gsm non-woven geotextile was placed on it, then with landfill liner systems for second layer, and finally 18 inches (46 cm) of soil was covered. The landfill liner systems is composed of 1mm HDPE geomembrane liner by professional welding and installation because of its superior physical properties, low number of cold cracks and accelerated installation.
BPM’s experienced construction team shortened the construction cycle and saved customers a lot of money. North Columbia will be snowfall in September, so expedited installation reduced the risk of prolonged weather delays, customers are satisfied, and hope to maintain a long-term relationship with BPM.
