Marchioni pointed out that coal has a lot of porosity and can hold a lot of gas. “Permeability is the problem with CBM,” he explained. He compared CBM with natural gas, saying, “If you can find the (natural) gas, you can probably get it out.” That’s not always the case with CBM.
China came during Marchioni’s television interview. China nearly always does end up a topic of discussion, when talking about CBM. Because China’s coal mines account for approximately 80 percent of coal mining fatalities, China has campaigned to reduce the number of deaths. China’s state-owned CBM company, China United Coalbed Methane Company, has continued granting CBM concessions to foreign-owned companies to help vent the methane from their coal mines. “The Chinese government is pushing very hard to have their coal mines degassed,” Marchioni said. He explained that the Chinese were beginning to drill for methane before starting their coal mining operations.
